how to have python check for certain word/phrase for raw input

[PythonNotSoGuru]

Hi everyone i was just wondering if there is anyway to have python check for a specific word or phrase in a raw input value. If you could please provide a small example code chunk to help me along that would be great. I have no idea how this would be attempted so any suggestions would be terrific.

platform windows

if word in raw_input("Ente r a sentence: "):
print "found word"
else:
print "word not found"
