When should you add Python to PATH?

• If you only have one version of Python installed, then you can safely add Python to PATH.
• If you need multiple versions of Python installed on the same computer, then it is advised not to add Python to PATH.

If you want to add python.exe to the PATH, then check mark the option.

Numbers and Math

Here’s a simple Python program that meets the instructions from the image:

num1 = 25000000        # without underscores
num2 = 25_000_000      # with underscores

print(num1)
print(num2)

Explanation:

• 25_000_000 is the same as 25000000 in Python—underscores just make large numbers easier to read.

• The program prints num1 and num2 on separate lines as requested.
