Python: for loop - print on the same line [duplicate]

Answer 1

Use end parameter in the print function

print(new_item, end=" ")

There is another way to do this, using comprehension and join.

print (" ".join([function(word) for word in split]))

Answer 2

The simplest solution is using a comma in your print statement:

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

Note that there's no trailing newline; print without arguments after the loop would add it.

Answer 3

As print is a function in Python3, you can reduce your code to:

while item:
    split = item.split()
    print(*map(function, split), sep=' ')
    item = input('Enter a sentence: ')

Demo:

$ python3 so.py
Enter a sentence: a foo bar
at foot bart

Even better using iter and partial:

from functools import partial
f = partial(input, 'Enter a sentence: ')

for item in iter(f, ''):
    split = item.split()
    print(*map(function, split), sep=' ')

Demo:

$ python3 so.py
Enter a sentence: a foo bar
at foot bart
Enter a sentence: a b c
at bt ct
Enter a sentence: 
$
