str.join(iterable)ΒΆ
It puts all the elements of iterable into one string named str.
Thats not what the documentation says...
So it returns a string.
Thats true.,
When trying to understand how a function works, or debug these kinds
of
errors use the >>> prompt to experiment. It's the definitive way of
seeing what
Python will do.
For example try:
"123".join([5,6,7])
Can you see what Python has done?
Use the >>> prompt it is one of the most powerful tools you have.
