why my python read makes so many new lines?

I want to do the following, I want to read a txt file line by line and then print the input to the console, So i have the following input.txt:

1
2
3

and the python code looks like this:

file = open("input.txt")

for line in file:
    print line

why I get a output like:

1

2

3

and not:

1
2
3

how to avoid this?

The print function in Python3 lets you suppress the line ending. In Python2.6+ you can import the print function from the __future__ module

from __future__ import print_function # required for Python2
file = open("input.txt")

for line in file:
    print(line, end="")

for line in file:
    print line

print prints some text and then also prints a '\n' new line after it. You can use a trailing comma to stop this:

for line in file:
    print line,

Or just .rstrip() it:

for line in file:
    print line.rstrip('\n')
