Simplifying multiple "or" conditions in if statement.

[DeaD_EyE]

if ('Ed' or 'Bob') in s:

This code checks always if 'Ed' in s:

The or operator is a binary operation, which is checking for trueness.
A str object with the length 0 is False. All other str objects are True.
With your code you'll always get 'Ed' after evaluating the expression.

What you want to do:

s = 'BobTom'

for name in ('Bob', 'Ed'):
    if name in s:
        print('Name {} is in {}'.format(name, s))

If you want to check if any of the names is in the string, you can write it more compact:

any(name in s for name in ('Bob', 'Ed'))

If you want to check if all the names are in the string, you can use the built-in function all:

all(name in s for name in ('Bob', 'Ed'))
