i++ In python showing me error [duplicate]

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

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

i += 1

i+=i+1 is not equal to i++

I have noticed, right after:) But thanks for reminding:)

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.

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.
