How to print spaces between values in loop?

While others have given an answer, a good option here is to avoid using a loop and multiple print statements at all, and simply use the * operator to unpack your iterable into the arguments for print:

>>> print(*range(5))
0 1 2 3 4

As print() adds spaces between arguments automatically, this makes for a really concise and readable way to do this, without a loop.

>>> for i in range(5):
...    print(i, end=' ')
...
0 1 2 3 4 

Explanation: the sep parameter only affects the seperation of multiple values in one print statement. But here, you have multiple print statements with one value each, so you have to specify end to be a space (per default it's newline).

Just add the space between quotes after the end. It should be:

end = " "

In Python 2.x, you could also do

for i in range(5):
    print i,

or

print " ".join(["%s"%i for i in range(5)])
