How to Suppress the Newline After a Print Statement

How can I suppress the newline after a print statement?

The question asks: "How can it be done in Python 3?"

Use this construct with Python 3.x:

for item in [1,2,3,4]:
    print(item, " ", end="")

This will generate:

1  2  3  4

See this Python doc for more information:

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

--

Aside:

in addition, the print() function also offers the sep parameter that lets one specify how individual items to be printed should be separated. E.g.,

In [21]: print('this','is', 'a', 'test')  # default single space between items
this is a test

In [22]: print('this','is', 'a', 'test', sep="") # no spaces between items
thisisatest

In [22]: print('this','is', 'a', 'test', sep="--*--") # user specified separation
this--*--is--*--a--*--test

How to print without a newline or space

In Python 3, you can use the sep= and end= parameters of the print function:

To not add a newline to the end of the string:

print('.', end='')

To not add a space between all the function arguments you want to print:

print('a', 'b', 'c', sep='')

You can pass any string to either parameter, and you can use both parameters at the same time.

If you are having trouble with buffering, you can flush the output by adding flush=True keyword argument:

print('.', end='', flush=True)

Python 2.6 and 2.7

From Python 2.6 you can either import the print function from Python 3 using the __future__ module:

from __future__ import print_function

which allows you to use the Python 3 solution above.

However, note that the flush keyword is not available in the version of the print function imported from __future__ in Python 2; it only works in Python 3, more specifically 3.3 and later. In earlier versions you'll still need to flush manually with a call to sys.stdout.flush(). You'll also have to rewrite all other print statements in the file where you do this import.

Or you can use sys.stdout.write()

import sys
sys.stdout.write('.')

You may also need to call

sys.stdout.flush()

to ensure stdout is flushed immediately.

Python: avoid new line with print command

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().

Print statements without new lines in python?

This can be easily done with the print() function with Python 3.

for i in x:
  print(i, end="")  # substitute the null-string in place of newline

will give you

......

In Python v2 you can use the print() function by including:

from __future__ import print_function

as the first statement in your source file.

As the print() docs state:

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

Note, this is similar to a recent question I answered ( https://stackoverflow.com/a/12102758/1209279 ) that contains some additional information about the print() function if you are curious.

Removing '\n' character from print statement

You can set the end parameter of print to be an empty string (or some other character):

print(details, file=userquiz, end='')

From the docs, you can see that it defaults to a newline:

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

Print objects to the text stream file, separated by sep and followed by end. sep, end, file and flush, if present, must be given
as keyword arguments.

This is what is being printed to the file currently.

How to Print in Python 2.7 without newline without buffering

Include this at the beginning of your file:

from __future__ import print_function

Then you can use both end and flush named parameters as if you were on Python 3. It seens you are missing the flush parameter:

print("We're doing something...",end='', flush=True)

If you can't or would not like to do that for some reason, you should end your legacy print statement with a sole comma. If you need the partial line to be printed, then you have to manually call sys.stdout.flush() soon after printing:

 print "We're doing something...",
 sys.stdout.flush()
 ...
 print "Done!"

How do I keep Python print from adding newlines or spaces?

import sys

sys.stdout.write('h')
sys.stdout.flush()

sys.stdout.write('m')
sys.stdout.flush()

You need to call sys.stdout.flush() because otherwise it will hold the text in a buffer and you won't see it.
