How to count word “test” in file on Python?

Question

I have a file consists of many strings. Looks like

sdfsdf sdfsdfsdf sdfsdfsdf test gggg uff test test fffffffff sdgsdgsdgsdg sdgsdgsdgsdg uuuttt 5

Answer 1

It will count number of tests in the whole file:

f = open('my_file.txt', 'r')
num_tests = len([word for word in f.read().split() if word == 'test'])
f.close()

Note that it will NOT match words like tester, tested, testing, etc.... If you want to also match them, use instead:

f = open('my_file.txt', 'r')
num_tests = len([word for word in f.read().split() if 'test' in word])
f.close()
