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

Printing to the terminal in Python 3 is usually "line buffered". That is, the whole line is only printed to the terminal once a newline character is encountered.

To resolve this problem you should either print a new line at the end of the for loop, or flush stdout.

eg.

for entry in categories:
    print(entry, ", ", end='')
print(end='', flush=True) # or just print() if you're not fussed about a newline

However, there are better ways of printing an array out. eg.

print(", ".join(str(entry) for entry in categories))
# or
print(*categories, sep=", ")
