Print statements without new lines in python?

Question

I was wondering if there is a way to print elements without newlines such as

x=['.','.','.','.','.','.']

for i in x:
    print i

and that would print ........ instead of what would normally print which would be

.
.

Thanks!

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.

Note that this will only work in Python 3 or when you have `from __future__ import print_function` at the beginning of your file. – omz Aug 25 '12 at 17:15
@omz Yes that is correct - I was just adding a note about that while you were posting your comment. – Levon Aug 25 '12 at 17:17

import sys
for i in x:
    sys.stdout.write(i)

or

print ''.join(x)

I surprised no one has mentioned the pre-Python3 method for suppressing the newline: a trailing comma.

for i in x:
    print i,
print  # For a single newline to end the line

This does insert spaces before certain characters, as is explained here.

As mentioned in the other answers, you can either print with sys.stdout.write, or using a trailing comma after the print to do the space, but another way to print a list with whatever seperator you want is a join:

print "".join(['.','.','.'])
# ...
print "foo".join(['.','.','.'])
#.foo.foo.

For Python3:

for i in x:
    print(i,end="")
