What are some common errors when creating iterables in Python?

Some common errors include using incorrect syntax, forgetting to use parentheses for generators, and modifying the iterable while iterating.

Can you give me an example of incorrect syntax?

Sure! A common mistake is forgetting to use brackets for lists, like this: my_list = 1, 2, 3 instead of my_list = [1, 2, 3].

What about generator expressions? What mistakes should I avoid?

When using generator expressions, make sure to use parentheses. For example, gen = (x*x for x in range(5)) is correct, but gen = x*x for x in range(5) is not.

How can I avoid modifying an iterable while iterating?

To avoid this, you can create a copy of the iterable or use a list comprehension to generate a new list based on the original.
