You can just do

>>> 'script executed in {:.2f} seconds'.format(elapsed_time)
'script executed in 0.12 seconds'

In your original code, you have two fields {}

, but only gave one argument, so it gave the error "tuple index out the range".

You have created two format fields:

print('script executed in {time}{1:.2f} seconds'.format(time=elapsed_time))
#                         ^1    ^2

but gave only one argument str.format

:

print('script executed in {time}{1:.2f} seconds'.format(time=elapsed_time))
#                                                       ^1

You need the number of format fields to match the number of arguments:

print('script executed in {time:.2f} seconds'.format(time=elapsed_time))
