# How to create installers for your Python application?🤔

## Requirements
1. Debian operating system.
2. Windows operating system with Python 3, pip and inno setup installed.

## Creating inno setup installer (on windows)
In order to create an installer, we must convert the application script to executable. We can do this using pyinstaller.  
Step 1: create a directory `my_app`.  
Step 2: Create a new file `my_app/app.py` and copy the following contents to it:
```
import tkinter as tk

root = tk.Tk()
tk.Label(master=root, text="Hello world", font=("Arial", 30)).pack()
root.mainloop()
``` 
Step 3: Navigate to `my_app` directory and run the following command in CMD:  
```
pip install pyinstaller
pyinstaller --onefile app.py -w
```
Step 4: Wait for the command to complete and open inno setup compiler.  
Step 5: On the inno setup welcome screen, click "Create a new script file using the Script Wizard" and hit ok.  
Step 6: Follow on screen instructions (main executable file is in `my_app/dist/app.exe`).  
Step 7: Compile the script and done!

## Creating deb package (On Debian OS)
Just like windows, we must create an executable from our script for deb package.  
Step 1: Create a directory `my_app`  
Step 2: Create a new file `my_app/app.py` and copy the following contents to it:
```
import tkinter as tk

root = tk.Tk()
tk.Label(master=root, text="Hello world", font=("Arial", 30)).pack()
root.mainloop()
```
Step 3: Navigate to `my_app` directory and run the following command in terminal:
```
pip install pyinstaller
pyinstaller app.py -w
```  
Step 4: wait for it to complete and create the following directories.  
```
my-app_1.0.0/DEBIAN
my-app_1.0.0/my_app
my-app_1.0.0/usr/share/applications
```  
Step 5: Create a file `my-app_1.0.0/DEBIAN/control` and copy the following contents into it.  
```
Package: my-app
Version: 1.0.0
Architecture: all
Maintainer: [Your name]
Copyright: [year] [Your name]
License: MIT
Homepage: [homepage url]
Description: My deb package.
```  
Step 6: Create a file `my-app_1.0.0/usr/share/applications/my-app.desktop` and copy the following contents into it.  
```
[Desktop Entry]
Type=Application
Exec=/my_app/app
Hidden=false
NoDisplay=false
Name=My app
Comment=My app.
```  
Step 7: Copy all files and folders from `my_app/dist` to `my-app_1.0.0/my_app`  
Step 8: navigate to the parent directory of `my-app_1.0.0` and execute the following command:  
```
dpkg-deb --build my-app_1.0.0
```  

Step 9: Wait for it to complete and done! You will find a deb package named `my-app_1.0.0.deb`
