Converting between types in Python

Moving values between types with constructor calls.

answer = "42"
number = int(answer)
precise = float(answer)

count = 7
label = str(count) + " items"

pieces = list("abc")
unique = set([1, 1, 2, 3])
frozen = tuple([1, 2, 3])

digit = int("ff", 16)

How it works

1. int and float parse numbers out of strings.
2. str turns numbers back into text for display.
3. list, set, and tuple reshape any iterable.
4. int with a base parses hex like "ff".
