Hey, I'm new to the Python world, but I do have experience in several
other languages. I've been running through a tutorial, and I decided that
I'd make a program that runs through a list, finds if there are any
duplicates. The program, doesn't work, but since its a first build I
wasn't too worried about it. I'd be highly impressed if I got the program
to run correctly in the first build, I want to debug it myself later.
What does worry me, is that I can't seem to get the program by a
certain spot. It keeps giving me the same error, and I don't know why.
The code:
ttllst=[4,3,45,3]
cnto=0
cntt=1
rept=-1
print cnto
print cntt
print ttllst[cnto]
print ttllst[cntt]
choice=raw_input("Begin? ")
if choice == "yes" or choice == "y":
while cnto<>len(ttllst)+1:
if ttllst[cnto]==ttllst[cntt]:
rept=rept+1
if cntt==len(ttllst):
print ttllst[cnto],"appears in the list",rept,"times."
cntt=-1
cnto=cnto+1
rept=-1
cntt=cntt+1
print "done."
After running the program I get error:
Traceback (most recent call last):
File "C:\Python24\Projects\repeatfinderlist", line 13, in -toplevel-
if ttllst[cnto]==ttllst[cntt]:
IndexError: list index out of range
Now, if I remove the while, and the If/choice lines like so:
ttllst=[4,3,45,3]
cnto=0
cntt=1
rept=-1
print cnto
print cntt
print ttllst[cnto]
print ttllst[cntt]
if ttllst[cnto]==ttllst[cntt]:
rept=rept+1
if cntt==len(ttllst):
print ttllst[cnto],"appears in the list",rept,"times."
cntt=-1
cnto=cnto+1
rept=-1
cntt=cntt+1
print "done."
I get no errors. The program doesn't work, granted, but I get no errors.
Can anyone tell me what I'm missing?
Thanks!
