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?

Answer 1

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.”
