Python: avoid new line with print command

Question

When I use the print command, it prints whatever I want and then goes to a different line. For example:

print "this should be"; print "on the same line"

Should return:

this should be on the same line

but instead returns:

this should be
on the same line

More precisely I was trying to create a program with if that told me whether a number was a 2 or not

def test2(x):
    if x == 2:
        print "Yeah bro, that's tottaly a two"
    else:
        print "Nope, that is not a two. That is a (x)"

But it doesn’t recognise the last (x) as the value entered, and rather prints exactly: "(x)" (the letter with the brackets). To make it work I have to write:

print "Nope, that is not a two. That is a"; print (x)

And if e.g. I enter test2(3) that gives:

Nope, that is not a two, that is a
3

So either I need to make Python recognise my (x) inside a print line as the number; or to print two separate things but on the same line.

IMPORTANT NOTE: I am using version 2.5.4

Another note: If I put print "Thing" , print "Thing2" it says "Syntax error" on the 2nd print.

Answer 1

In Python 3.x, you can use the end argument to the print() function to prevent a newline character from being printed:

print("Nope, that is not a two. That is a", end="")

In Python 2.x, you can use a trailing comma:

print "this should be",
print "on the same line"

You don’t need this to simply print a variable, though:

print "Nope, that is not a two. That is a", x

Note that the trailing comma still results in a space being printed at the end of the line, i.e. it’s equivalent to using end=" " in Python 3. To suppress the space character as well, you can either use

from __future__ import print_function

to get access to the Python 3 print function or use sys.stdout.write().

Answer 2

Utilize a trailing comma to prevent a new line from being presented:

print "this should be"; print "on the same line"

Should be:

print "this should be", "on the same line"

In addition, you can just attach the variable being passed to the end of the desired string by:

print "Nope, that is not a two. That is a", x

You can also use:

print "Nope, that is not a two. That is a %d" % x #assuming x is always an int

You can access additional documentation regarding string formatting utilizing the % operator (modulo).

Answer 3

You simply need to do:

print 'lakjdfljsdf', # trailing comma

However in:

print 'lkajdlfjasd', 'ljkadfljasf'

There is implicit whitespace (ie ' ').

You also have the option of:

import sys
sys.stdout.write('some data here without a new line')

Answer 4

In Python 2.x just put a , at the end of your print statement. If you want to avoid the blank space that print puts between items, use sys.stdout.write.

import sys

sys.stdout.write('hi there')
sys.stdout.write('Bob here.')

yields:

hi thereBob here.

Note that there is no newline or blank space between the two strings.

In Python 3.x, with its print() function, you can just say

print('this is a string', end="")
print(' and this is on the same line')

and get:

this is a string and this is on the same line

There is also a parameter called sep that you can set in print with Python 3.x to control how adjoining strings will be separated (or not depending on the value assigned to sep)

E.g.,

Python 2.x

print 'hi', 'there'

gives

hi there

Python 3.x

print('hi', 'there', sep='')

gives

hithere

Answer 5

If you’re using Python 2.5, this won’t work, but for people using 2.6 or 2.7, try

from __future__ import print_function

print("abcd", end='')
print("efg")

results in

abcdefg

For those using 3.x, this is already built-in.
