Python string find

Question

I want to find a certain substring inside a string. The string is stored in a list of strings. How can i do it?

An example would helpful - what does the data look like, what does the search string look like, and what results do you want? — RichieHindle

So you're searching for all the strings in a list of strings that contain a certain substring? This will do it:

DATA = ['Hello', 'Python', 'World']
SEARCH_STRING = 'n'
print [s for s in DATA if SEARCH_STRING in s]
# Prints ['Python']

Edit at Andrew's suggestion: You should read that list comprehension as "Make a list of all the strings in the list DATA where SEARCH_STRING appears somewhere in the string."

+1 Very Pythonic! It might be best to explain your example though as a newcomer to Python might not be familiar with list comprehensions.
