Why is print() not working anymore with python?

Question

in fact this should not be a problem because it\'s fairly basic. I just want to print out an array of categories, but in one line and separated by comma.

for ent         


        

Answer 1

Check categories isn't empty - that'd make it print nothing - also I'd consider changing your code to make use of the sep argument instead (depending how large categories is):

print(*categories, sep=', ')

eg:

>>> categories = range(10)
>>> print(*categories, sep=', ')
0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Then you don't have to worry about flushing/trailing separators etc...
