Which works fastest in python?

Question

can you please tell me which code works fastest in python?
a='1'
b='2'
print (a,"is not equal to", b)
print (a+"is not equal to"+b)
print ("{0} is not equal to{1}".format(a, b))

Answer 1

not really sure why you need the speed of a print statement, but I would bet on the first one as the second and third need to do some string operations before passing a single value to print. However that guess relies on the assumption that print itself has a clever way of handling multiple arguments 😀. If you need to know for sure put each print in a loop with few thousand iterations and time the loops to get an average as single statements performance can vary depending on your system state at the moment of execution.

Answer 2

Nikolay Nachev does python have a concept of flushing the output to stdout somewhat independently of the actual print statement as in C? Perhaps not as python is generally interpreted?

Answer 3

by taking the tests,
1st-{0} is not equal to {1}
2nd-a+"is not equal to"+b
3rd-a,"is not equal to", b
