No output in shell?

[g_109]

This is my first time posting in this forum so sorry in advance if i have done something wrong or not explained the problem clearly!

Hi,
so my python program to create a coffee ordering system was working great but has now suddenly stopped working. When I go to the shell and enter main() or define main () nothing happens. Literally no errors. nothing.

Here is the code:

Here is the output in the shell:

(sorry if the link doesn't work, but it just basically shows how it jumps a line down from where i type "main()" and then the chevrons disappear!)

Well first things first. Don't put caps in thread name and prefereably use a meaningful title instead of "I need help" and so.
Second, put your code in Python code tags, you can find help here.

Thankyou! I have edited my post accordingly, this is my first post so I know nothing about the rules.

Any suggestion of what to do??

[j.crater]

The rules may have been written when you registered or just before posting the thread, but that's fine, thanks for editing the post accordingly.

First, in last line (132), you have a trailing "]" which is no use.
In line 44 you have customerNum + 1, which won't do much because it doesn't store it to a variable.

The code then executes alright for me (gives welcome message and asks for name input). Although it's weird you didn't get any error messages.

Although it's weird you didn't get any error messages.

it just go in endless loop (of course, after removing the extra ] you mention - maybe it did come when tags were added)

At which point it does? Seems I missed that.

exactly at line 43-44 where you said. because they don't assign it, value always stays 0, so it doesn't exit the while loop

[j.crater]

Oh geez, too obvious for me to notice it seems :D Good one.

Thankyou both for the help! I really appreciate it! :)
