Demonstrating the difference between using walrus operator and not using walrus operator with simple example

walrus_example.py

#!/usr/bin/python3
# Prior to Python 3.8
# Assigning a value to variable and then evaluating the expression in different lines
python_version = 3.7
print(f'Python version with walrus operator? : {python_version >= 3.8}')
print(f'Applicable for Python version: {python_version}')

# Reset variable
python_version = None

# Python 3.8
# Both evaluating the expression and then assign the value to the variable in the same line
print('Python version with walrus operator? :', (python_version := 3.8) >= 3.8)
print(f'Applicable for Python version: {python_version}')
