Why is case sensitivity important in Python variable names?

• It allows for more creative variable names.

• It makes the code run faster.

• It is a requirement for all programming languages.

• It helps Python distinguish between different variables.

What is the PEP 8 recommendation for naming variables?

• Use camelCase for variable names.

• Use all uppercase letters.

• Use all lowercase letters and separate words with underscores.

• Use numbers at the beginning of variable names.

Why is it important to choose meaningful variable names?

• To reduce the file size of the code.

• To make the code easier to understand and maintain.

• To ensure the code runs without errors.

• To make the code look more professional.

How did older computers influence variable naming practices?
