Something I forgot to add. This idea of side-effects with the conditionals is
actually the whole point of the Python built-in functinos any() and all().
any() will evaluate a generator expression and stops when one of them
evaluates to True, and all() works the same, but stops when a False is

Yes.
I don't know how python actually does it but in a general
sense there is not much if any diffe

Hello,
Suppose we want some block of code to be executed when both '*a'* and
'*b'*are equal to say 5. Then we can write like :
*if a == 5 and b == 5:*
*# do something*
But a few days ago, I just involuntarily wrote a similar condition check as
:
*if a == b and b == 5:*
*# do something *

Welcome, and congratulations on starting with Python!
No forgiveness needed for asking questions or making mistakes; the
important thing is to learn from both.

This opens the file and reads all the lines but it
doesn't store the result anywher

Hi all!
I'm embarrassingly new at Python, so please forgive my probably simple
mistakes.
So I called readlines() on a file, and I'm wondering how I can check the
equality of a specific line with a raw_input set variable as a condition. For
example,
file = open('filename.txt,' 'r')
file.read
