Running timeit in a for loop with index as input number

python, python-2.7, timeit

Solution

Use string formatting:

for i in range(1, 30):
    t = timeit.Timer('Fib({:d})'.format(i), 'from problem1 import Fib').timeit()
    print('The time for {i:d} is {t:0.2f}'.format(i=i, t=t))

Problem

Im trying to run timeit to time a python function like so: ``` for i in range(1, 30): print 'The time for ' + str(i) + ' is ' + str(timeit.Timer('Fib(i)', 'from problem1 import Fib').timeit()) ``` `global name 'i' is not defined` even though I have i defined in the start of the program as `global i` When I run timeit like so: ``` print timeit.Timer('Fib(5)', 'from problem1 import Fib').timeit() ``` it works. Any suggestions?
