Answer 1

This should work.

   from collections import Counter
   with open('myfile.txt', 'r') as f:
       words = f.read().split()
       counts = Counter(words)

   print counts["test"] #counts just of exact string "test"
   #find all strings containing test (e.g 'atest', 'mytest')
   print sum([val for key,val in counts.iteritems() if "test" in key])
