i++ In python showing me error

Question

I cant use i++ in python. My code is

i=0
while i<10:
   print i
   i++

But it works fine if I replace i++ with i=i+1 it works. What have I done wrong

"What have I done wrong": You have used `++` in a python program. — Antti Haapala -- Слава Україні, Mar 02 '15 at 10:37

There is no ++ operator in python. You must use

i += 1

i+=i+1 is not equal to i++ – Md. Mahamudul Hasan Khan Mar 02 '15 at 10:34
I have noticed, right after:) But thanks for reminding:) – Beri Mar 02 '15 at 10:38
Even `i += 1` is not the same what you expected `i++` to do. Integers are immutable in Python. With `i += 1` you create a new integer behind the scenes. – Matthias Mar 02 '15 at 10:50

It's just that i++ isn't supported in python. Replace that loop as follows:

i=0
while i<10:
   print i
   i += 1 # add 1 to i.

Or, even better (in case you are indeed using loops that way):

for i in range(0, 10):
    print i

Please take a look here for a list of all operators.
