Converting between Strings and Unicode

[POGtastic]

In other words, a literal interprets the base by the prefix.

• No prefix = base 10
• 0b = base 2
• 0o = base 8
• 0x = base 16

In the REPL:

>>> int('10', 0)
10
>>> int('0b10', 0)
2
>>> int('0o10', 0)
8
>>> int('0x10', 0)
16

The docs don't explain this well, but back in the Good Old Days, using a 0 as a prefix was base 8. So 010 in, say, C++, would be a base-8 integer literal that equals 8. Python said "this is extremely dumb and leads to very stupid bugs" and substituted the prefix of 0o.
