• In case you have not found:-  
• The very first step towards Python Programming would be to download the tools required to run the python language. We will be using Python 3 for the course. You can download the latest version of Python depend on Python officail website so download from https://www.python.org/downloads/
• Note :- If you are using Windows OS, then while installing Python make sure that "Add Python to PATH " is checked. 
• Getting an IDE for writing programs:  
• You can use any IDE of your choice, however you are recommended to use VS-Code,  
• You can download it from https://code.visualstudio.com/

 Python Write 1st Program :  

• Python is an interprested programming language, this means that as a developer you write Python (.py) files in a text edito and then put those files into the pytgon interpreter to be executed.  
• The way to run a python file is like on the command line
• Where "text.py" is the name of your python file. 

D:\Learning File\Notepad\Python>

• Let's write our first python file called text.py which can be done in any text editor. 

print ("Hello Dear Freinds Welcome to TechnologySecret") 

• Sample as that. Save your file. Open your command line, navigate to the directory where you saved your file, and run. 
• How to run let's see :  

D:\Learning File\Notepad\Python>python text.py 

• The Output should read: 

Hello Dear Freinds Welcome to TechnologySecret

 Python Command Line : 

• To test a short amount of code in python sometimes it is quicktest and easiest not to write the code in a file. This is made possible because Python can be run as a command-line itself. 
• Type the following on the Windows, Mac , or Linux command Line. 
• D:\Learning File\Notepad\Python> python
• Or if the "python" command did not work, you can try "py": 
• D:\Learning File\Notepad\Python> py
