Question - the following lines are from one of the first pages of the tutorial. Code: >>> word = 'Help' + 'A'
>>> word
'HelpA'
>>> '<' + word*5 + '>'
'' Why does the last line have to have the " + "'s around word*5 to work? Code: >>> word*5
'HelpAHelpAHelpAHelpAHelpA'
>>> ''
''
>>> '<'word*5'>'

That's the page, it's like halfway down, section on concatenates.
Don't understand why '<' + word*5 + '>' works but '<'word*5'>' does not. |
Assuming I'm not a complete idiot:
The +s concat those strings. Without that it has no idea what you're trying to do. It'd be like typing
5 3*5 5
into a calculator. It doesn't know that you're trying to add them together.
For the user input problem, you can print out the usercmd to see what it receives from the input(). That or run it through a debugger to find out why it's not working. Maybe remove the ORs to see if it works without. It's been a long time since I used Python 2 even so I'm not 100% on the syntax at all.
