Python programs are executed line by line.

s = "C'est la vie"
# This is a comment
print(s)

This program has three lines containing two instructions:

1. First, we store the text C'est la vie (without quotations) in a variable named s.
2. The second line contains a comment, indicated with #, which is ignored during execution.
3. The third line prints whatever is stored in variable s.

The program will print the text C'est la vie.
