Which of the statements below is true about indentation in Python?

• Indentation only matters in for loops. Then, everything must be indented one level.

• Indentation never matters in Python. You can align your code any way you like, but indentation makes your code easier to read.

• Indentation always matters in Python. Every statement must be aligned correctly.

• Indentation only matters in functions. Then, everything must be indented one level.

IV. Statements in a for loop do not need to be indented

V. It is not possible to have the range value count 6, 12, 18, 24
