Hello, I am a student trying to figure out Python. I am getting errors that I
don't know how to fix. What do you do after you get the error message and
something is highlighted? Does that have to be deleted? Anyway, here is what I
mean...
def main():
print
#initialize variables
playerOne = 'No Name'
playerTwo = 'No Name'
#call to inputNames
playerOne, playerTwo = inputNames(playerOne, playerTwo)
#while loop to run program again
while endProgram == 'no':
#initialize variables
winnersName = 'NO NAME'
p1number = 0
p2number = 0
#call to rollDice
winnerName = rollDice(p1number, p2number, playerOne, playerTwo,
winnerName)
#call to displayInfo
winnerName
endProgram = raw_input('Do you want to end program? (Enter yes or no):
')
When posting a question, you should always specify the Python version
and OS, though it probably doesn't matter here.
As others have said, please paste the exact error message. This is a
text mailing list, so any highlighting you may have tried to include is
lost on most of us. Please post in a text message, not html, as many
things can go wrong in the re-interpretation, especially in any source code.
I pasted your code into a text editor, saved the file, and ran it a
terminal window in Python 2.7 under Linux,
davea@think2:~/temppython$ python glen.py
File "glen.py", line 25
endProgram = raw_input('Do you want to end program? (Enter yes or
no): ')
^
IndentationError: unexpected indent
davea@think2:~/temppython$
As you can see the callstack shows the line that has a problem, and
shows s a specific error message. The problem is that you indented a
line improperly. You only add to the indentation within a function, an
if/else statement statement block, class, with clause, etc. Ordinary
statemdents have to line up with the ones before, not counting comments.
If you line up the endProgram line with the previous winnername line,
this particular error will go away. But you have others.
I notice you mix spaces and tabs for indentation, which is dangerously
confusing. You should stick to one or the other, and I prefer spaces.
I configured my text editor (emacs) to turn any tabs into 4 spaces, so
that I won't get into trouble.
in some places you only indent by one space. That's hard to read and you
can wind up with problems from that. Better to stick with 4, though
some people seem to prefer 2.
Next problem is:
davea@think2:~/temppython$ python glen.py
File "glen.py", line 44
elif p1number > p2number:
^
IndentationError: unindent does not match any outer indentation level
This error is because the elif clause does not line up with the if clause.
But a bigger problem in that portion of code is that you're apparently
starting a new function, but never define it. No def line follows the
comment: #this function displays the winner
If you add that def xxx(): line, and indent the if, then the elif will
line up as expected.
After fixing that, the next error is:
Traceback (most recent call last):
File "glen.py", line 51, in <module>
main()
File "glen.py", line 15, in main
while endProgram == 'no':
UnboundLocalError: local variable 'endProgram' referenced before assignment
That comes because you have a while statement that refers to the
variable endProgram, which has not been yet bound to a value. You need
endProgram = "no"
before that if statement.
In each of these cases, the error message tells you pretty closely
what's wrong, and where. You will need to learn to read the error
messages, the tracebacks.
Your next problem is one of program logic, and I leave it to you.
