how count words "test". tried, have result

f = open("file") words =  0 s in f:     = s.find('test')     if > -1:         words += 1 print(words) f.close() 

and script counts strings contain word "test". how count words?

if want find matches:

with open("file") f:     numtest = f.read().count("test") 

if want find word matches:

with open("file") f:     numtest = f.read().split().count("test")
