Syntax error iterating over tuple in python

Question

I am new to Python and am unsure of the best way to iterate over a tuple.

The syntax

for i in tuple
    print i

causes an error. Any help will be much appreciated! I am a ruby programmer new to python.

This is the sort of question that makes google users hate SO. The title sounds so useful (and something one would google), but the question is so trivial and un-informative. — tacaswell, Oct 02 '13 at 02:54

That is an error because the syntax is invalid, add a colon:

for i in tup:
    print i

Also, you should not use tuple as the name for a variable, as it is the name of a built-in function.

One really nice way to avoid using reserved names for variables is to use Pylint (http://www.pylint.org/) to check your code every time you save. I use Aptana with Pydev and Pylint to do this. – Carl Oct 02 '13 at 02:42

for i in my_tuples_name:
    print i

You don't iterate over the keyword tuple, you iterate over your variable.

You seem to have forgotten a colon.

for i in my_tuple:
    print i

EDIT: And I didn't notice you were iterating over the keyword tuple, as noted. by F.J. and Jakob Bowyer.
