Using For in Python

Yes, using a data strip is the idiomatic way of doing it in Python and does not have the for you know in other languages. What you can do is use while , is almost equal to for traditional.

x = 0
while x < 3:
    print(x)
    x += 1

Idiomatic form:

for x in range(0, 3):
    print(x)

See running on ideone .

Python has else for for which is useful and rare in other languages.

Complementing the answer, note that you can use range or xragne in the idiomatic form reported in the previous answer.

Using the range pre-allocates all items to be iterated in memory, which can be a problem if the numbers are too large. In these cases it is more recommended to use xrange, which acts as a generator, allocating objects on demand.
