file.readlines() returns a list of lines. You can either call find on 
each
element in this list, like:

for line in myfile.readlines() :
     if line.find('my particular string') :
         do_something()

of just read in the whole file, if you are not interested in the 
particular
line, where 'my particular string occurs':

myfile.read().find('my particular string')
