Hello there! In this article we are going to create a programmer way to write an application. We will write an application using Python.

Ideation

So, as you all know that we have a specific format to write an application. In this post, I've chosen a leave application. Firstly, what we want is the sample of the application. Then, we are going to format the sample of the application with the important information. And at the end, we'll create a new file to output the text application and save it.

Prerequisites

A basic knowledge of file handling and string formatting.

The way I am going to make the program is using file handling in Python with string formatting. But you can also just make the use of string formatting to modify the program.

How?

Firstly I saved a very raw and simple sample of application written in a file named, "letter.txt". I've used a simple format. Modify the file as per your requirements.

the Principal

{school_name}

Subject: Sick Leave Application

I am {name} of {class_name} of your institute. I am writing this application to inform you that I am suffering from {reason} and therefore, I want sick leave from school. I got this infection last night and I will not be capable to come to the office for from {start_date} for a several days. As advised by my doctor, I should take rest and recover appropriately before continuing work. The report from the doctor is also attached for your reference.

Kindly grant me a leave for {no_days} days.

Yours Sincerely,

{name}

Note: Just keep the data that is to be changed with the application inside "{ }" brackets. And use a single unique word to define the information used inside it. We are going to change this information using string formatting

Now create a Python script file, say "letter.py" and start to code.

Coding

Firstly, we are using the template saved in our file, "letter.txt". So, we'll have to use it, open and read the content inside it. We are going to use the concept of file handling here.

  letter = open("letter.txt", "r")
  text = letter.read()

In these two lines, I've opened the file, in read mode (because we don't want to modify the file) and then I've read the content inside the file using read function and stored it in a variable, text.

Now, we have got the format in the text variable. Now, just replace those reference variables written inside the "{ }" brackets with the required data.

We're going to make the user input the required data. So, let's make some variables to let the user input some data.

  name = str(input("Enter your name: "))
  school_name = str(input("Enter your school's name: "))
  class_name = str(input("Enter the class: "))
  reason = str(input("Enter the reason for being absent: "))
  start_date = str(input("Enter the date from which leave starts: "))
  end_date = str(input("Enter the date from which leave ends: "))
  no_days = str(input("Enter the no. of days: "))

Note: I've used the same word references stored in the file inside "{ }" brackets. You can also do the same to remove any confusion.

Now, everything is well setup for us.

At last, We have to change the content in the text variable.

  temp_str = f"{text}".format(name=name, school_name=school_name,
  class_name=class_name, reason=reason, start_date=start_date,
  end_date=end_date, no_days=no_days)

I've created a variable and then changed its content with the text content of text variable, using string formatting. And after that in the same variable I've replaced the references with the variables.

This is a bit complicated to see as I've combined two steps in one. But, just look at it once and you will get it easily. If not, separate the two steps and print them one by one and see the difference.

At the end, close the opened file, "letter.txt".

  letter.close()

Now, you have created your application using python. Print the "temp_str" variable and see the output.

Here, we are going to make a new output file to save the application.

So, we'll again use the concept of file handling.

  output = open("output.txt", "w")

  output.write(temp_str)

  output.close()

Congratulations! You have created a Python program to create your own application.

Code:

print("""

         ___         ___   ___            ___

|    |  |     |     |     |   |  |\\  /|  |

|    |  |__   |     |     |   |  | \\/ |  |__

| /\\ |  |     |     |     |   |  |    |  |

|/  \\|  |___  |___  |___  |___|  |    |  |___

""")

letter = open("letter.txt", "r")

text = letter.read()

name = str(input("Enter your name: "))

school_name = str(input("Enter your school's name: "))

class_name = str(input("Enter the class: "))

reason = str(input("Enter the reason for being absent: "))

start_date = str(input("Enter the date from which leave starts: "))

end_date = str(input("Enter the date from which leave ends: "))

no_days = str(input("Enter the no. of days: "))

temp_str = f"{text}".format(name=name, school_name=school_name, 

class_name=class_name, reason=reason, start_date=start_date,

 end_date=end_date, no_days=no_days)

letter.close()

# print(temp_str)

output = open("output.txt", "w")

output.write(temp_str)

output.close()

This article will teach you how you can test your typing speed, but in programmer style, with Python. Check how fast you can type by making your own software to calculate the basic things needed to get the idea of your typing speed. We are going to use PyGame for making this software. You can also make this with Tkinter or other GUI. But PyGame is a bit useful for making these kind of GUIs, so I used it.

Download a suitable landscape background image you want for this app and rename that to "bg.jpg". Download a cartoon png from anywhere, or follow this link. Rename the character to "char.png".

Make a text file named typing.txt containing the collection of some sentences, e.g.,

The quick brown fox jumps over the lazy dog
Anyone who lives in Antarctica is their for a scientific research station.

Save all these files at one location on your device, inside the same directory (folder).

Install PyGame

pip install pygame

Type this command in your terminal: cmd, bash, etc.. and press enter (run).

Code

Import modules

 import pygame

This is how the software looks...

When you are working with PyQt5, you are using the default OS style of application. The design looks very simple for apps. So, if you are making a cutom app, you will cuystomise the top bar in few cases to have a better design. So, when you are customising the design, you will see that the window has no longer been movable. Thus, you need to write the logic to make the window movable again.
The default Window app style looks like this

The code for doing this is given below...

PyQt5 draggable window Code


class movable(QtWidgets.QWidget):
    def __init__(self):
        super(movable, self).__init__()
    def mousePressEvent(self, event):
        if event.button() == QtCore.Qt.LeftButton:
            self.dragPosition = event.globalPos() - self.frameGeometry().topLeft()
            event.accept()
    def mouseMoveEvent(self, event):
        if event.buttons() == QtCore.Qt.LeftButton:
            self.move(event.globalPos() - self.dragPosition)
            event.accept()

You will have to first make a class like this. Then you have to pass the class as parameter in the main window code. Like this...


class mainWindow(movable, Ui_Form):
    def __init__(self):

Here UI form is the form of the design.

So, I think that's it for this post. See you in the next...

Make your own Python IDE + Text Editor like Notepad:

July 17, 2021, 4:33:43 PM (MrDev in a deep thought)

If you have used Python, you must be aware of the Python shell (the IDLE). We have one place where we write the code and to run the code, we need to switch between the windows. Some brilliant mind will say (with a sarcastic sound) "He calls himself a programmer and he is talking about IDLE... Lol hahaha."

Shut up! Okay? I use IDEs but something that you have made, even its worse than what you think that was worse, you will like that! And a programmer builds things. This is his work.

Now in this project, I created my own IDE with python using Tkinter.

Now let me assume that some of you are from Mars and they don't know what IDEs actually are? So basically, IDE stands for Integrated Development Environment. It provides a collection of different things needed for coding and creates an environment for coding fast. Well its obvious that I could not make something at once that can directly challenge VS code (one of the leading IDEs in). But I can make something more similar to a text editor (like Notepad). And basically, what we actually want in programming is a section to run the program and display the output. So, can't we combine the output and the editor part in the same window. So, it reduces our work to switch between the windows like we do in IDLE.

Well, that's all about the idea. I am going to create a new notepad. But don't laugh. Okay. It would have some more features than notepad. Believe me! Let's start!

Make your own Web Browser in Python using PyQt5. PyQt5 is a very powerful Python framework to make modern GUIs. With help of Python PyQt5 QtWebWidgets, it is very easy to amke your own custom web browser with a few lines of code.

PyQt5 Basic code


import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *

class MainWindow(QMainWindow):
    def __init__(self):
        # Main Window
        super(MainWindow, self).__init__()
        self.showMaximized()

app = QApplication(sys.argv)
QApplication.setApplicationName("Browser")
window = MainWindow()
app.exec_()

PyQt5 Browser code using QtWebEngine


import sys
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
from PyQt5.QtWebEngineWidgets import *

class MainWindow(QMainWindow):
    def __init__(self):
        # Main Window
        super(MainWindow, self).__init__()
        self.browser = QWebEngineView()
        self.browser.setUrl(QUrl('https://google.com'))
        self.setCentralWidget(self.browser)
        self.showMaximized()

        # nav bar
        navBar = QToolBar()
        self.addToolBar(navBar)

        backBtn = QAction("Back", self)     # back Button
        backBtn.triggered.connect(self.browser.back)
        navBar.addAction(backBtn)

        forwardBtn = QAction("Forward", self)   # forward Button
        forwardBtn.triggered.connect(self.browser.forward)
        navBar.addAction(forwardBtn)

        relBtn = QAction("Reload", self)    # Reload Button
        relBtn.triggered.connect(self.browser.reload)
        navBar.addAction(relBtn)

app = QApplication(sys.argv)
QApplication.setApplicationName("Browser")
window = MainWindow()
app.exec_()

The final look of the browser after the above code.

So, in the last post, I made a IDE + Text Editor in Python using tkinter library. Part 1 In this post, I am going to make the designs a little better now.

Few days ago, I decided to make the IDE a little better. So, I started working on it, as always. Seriously, I am a beginner at Tkinter. I don't know much about app designing. Probablly this is my first Tkinter app :) So yeah, the designs are not great but they look a bit better.
Here's a look of the app

So, If you want to use the IDE, download the exe file here...

Presently, Pyhton is one of the most popular languages in the world. Its design philosophy emphasizes code readability with its use of significant indentation. Python is an interpreted high-level general-purpose programming language. Its language constructs as well as its object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects. Thus it is widely used in many fields such as data science, AI, ML. Python frameworks such as django and flask are also a good choice for designing the backend side of a website. Also there are frameworks such as Tkinter and PyQt5 for designing apps gui.

Shut up! Okay? I use IDEs but something that you have made, even its worse than what you think that was worse, you will like that! And a programmer builds things. This is his work.

Now in this project, I created my own IDE with python using Tkinter.

Well, that's all about the idea. I am going to create a new notepad. But don't laugh. Okay. It would have some more features than notepad. Believe me! Let's start!

Finally, after adding a few things that clicked on my mind, I completed the IDE. This is the final look :)

So, I think that's it! If you want the code of this project, do let me know in the comments below! Right now, the link might not work.
