Skills Required

• Setup python development environment
• Basic Printing in Python

Please make sure to go through all the skills mentioned above to understand and execute the code mentioned below

Main Code

When a line in python starts with #, python will not execute the line.
So you can write any thing in a comment.

For example consider the following python code

# This is a comment which won't be executed
# Let's print Hello World!
print('Hello World!')

• The first two lines in the above code are comments, since they start with #
• Hence the first 2 lines will not be executed by python

Multi-line comments example are shown below. Multi-line comments are useful to write comments in more lines

"""  
This is a comment  
written in  
more than just one line  
"""
print('Hello World!')

Run this in Visual Studio Code

• Create a folder in your PC
• Open this folder in Visual Studio Code using menu File->Open Folder
• Open File Explorer
• Create a python file by any name, say hello.py and write the following

# This is a comment which won't be executed
# Let's print Hello World!
print("Hello world!")

• Run the code using menu Run -> Run Without Debugging
• You should see Hello world! printed in the terminal
• Notice the the first 2 lines are not executed since they are comments
