Simple Question

I'm looking for the simplest code to check if an imputed file contains an imputed string. If the the file does contain the sting, I would like the Python shell to print: 'Yes', and if not, to print: 'No'.

Thanks

print(('No','Yes')[goal in text_to_be_searched])

You can choose how you populate the goal and the text_to_be_searched strings. source is a file name.

Code:

>>> with open(source,'r') as pf:
...     text_to_be_searched = pf.read()
... 
>>> import sys
>>> goal = sys.stdin.read()[:-1]
mighty
mouse
^D
>>> print(('No','Yes')[goal in text_to_be_searched])
No
>>>
