[ANSWERED] Runtime

Question

How do I measure how long a program runs?
---
I got a task to write a word-guessing program. It can just list all the characters, but it is known that the testing program that tests my program uses a word from a file with a certain name. The file is like a dictionary - seems that it is the set of all possible words of my language.
So the question is -- which way the test server spends less time guessing the word - if I just list all the chars in alpabethical order or try to pre-guess using the file given?

Answer 1

import datetime
a=datetime.datetime.now()
#run code
print("Time taken",datetime.datetime.now()-a)

Answer 2

import time
start_time = time.time()
main()
print("--- %s seconds ---" % (time.time() - start_time))
