Count indexes using “for” in Python

Question

I need to do in Python the same as:

for (i = 0; i < 5; i++) {cout << i;} 

but I don\'t know how to use FOR in Python to get the index

Answer 1

Just use

for i in range(0, 5):
    print i

to iterate through your data set and print each value.

For large data sets, you want to use xrange, which has a very similar signature, but works more effectively for larger data sets. http://docs.python.org/library/functions.html#xrange
