### simple coding help, using the if and or functions

hello,
im brand new to python so im doing some simple exercises and i am stuck on one.

this is the code:

Code: Select all
>>> words= ["pizazz", "python", "zebra", "pizza"]
>>> for x in words:
...     if x[0] in 'z':
...         print x
...
zebra
>>> for x in words:
...     if x[-1] in 'z':
...         print x
...
pizazz
>>> for x in words:
...     if x[0] or x[-1] in 'z':
...         print x
...
pizazz
python
zebra
pizza

when i try to print all the words beginning or ending in z, python prints all the words. I am using python 2.7.2
Thank you for any help,love,
Rainy

### Re: simple coding help, using the if and or functions

Code: Select all
if x[0] or x[-1] in 'z':

This evaluates to True when any of these evaluates to True:
• x[0]
• x[-1] in 'z' -- you probably want to use == here instead of in

Solution:
Code: Select all
if x[0] == 'z' or x[-1] == 'z':
