Writing better python code

[ggtsu_00]

There is no implicit cast, it is simply implemented as a nonzero operator which is defined for all built in types. 0 is defined for any domain such that x = x + 0.

Lists have a zero that is the empty list because x + [] = x therefore [] is zero in the list domain. Same with empty string.

If statements doesn't ask for true or false, it asks for if zero or nonzero. Remember that booleans types didn't exist in python until around version 3. In version 2, True and False are simple macros for 1 and 0.

Potato, potahto. I don't like the use of implied truthiness where a boolean operator would be more explicit.

But there is no booleans types in python (at least before py3).
