How Can I Avoid Newlines and Spaces When Printing in Python?

Avoiding Newlines and Spaces in Output Strings

When using the print function in Python, it often adds a newline or space between the output values. To prevent this and achieve uninterrupted printing, consider using the sep and end parameters.

Python 3

In Python 3, specify end='' to eliminate newlines:

print('.', end='')

To remove spaces between arguments, use sep='':

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

To control both parameters simultaneously:

print('.', end='', sep='')

Python 2.6 and 2.7

For Python 2.6 and 2.7, you have two options:

1. Import Python 3's print function:

from __future__ import print_function

This allows the use of the Python 3 solution mentioned above.

2. Use sys.stdout.write() (recommended for Python 2):

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

This writes directly to the standard output stream, ensuring immediate printing. However, you may need to call sys.stdout.flush() to guarantee immediate output.
