Answer to Question #293563 in Python for chrisking4real

Question

• In math notation, leading zeros are OK, as in 02. What happens if you try this in Python and why?

Answer 1

If Python sees an 8 or 9 after a leading zero, then it complains about an invalid octal number.

Python number 10 in each number base.

1. decimal 10 the one we use every day cannot have a leading zero
2. binary 0b1010
3. octal 012 must have a leading zero
4. hexadecimal 0x0A
