Timeit timing a python function -

i trying time below function, shows me error, can't import name val_in_range, what's error, there other method better?

import timeit  x = 10000000  def val_in_range(x, val):     return val in range(x)  print (val_in_range(x,x/2))  timeit.timeit( 'val_in_range(x,x/2)', 'from __main__ import val_in_range, x',  number=10) 

output:

true traceback (most recent call last):   file "python", line 11, in <module>   file "<timeit-src>", line 3, in inner importerror: cannot import name 'val_in_range' 

replace timeit.timeit( 'val_in_range(x,x/2)', 'from __main__ import val_in_range, x', number=10)

with timeit.timeit(lambda:val_in_range(x,x/2), number=10)

you can print value directly using print statement.
