First point : this is not a string, but a list of strings. I suppose it
comes from a file.readlines() call. If you want the whole file content
as a single string, use file.read() instead - but take care of big files...

Or just use str object's methods...
f = open('mylogfile.log')
for line in f:
if "Request" in line:
print "got one"
