Formatizer provides literal string formatting for Python versions older than 3.6. This replaces the need for substitution using % or the format function.

Formatizer is covered by unit tests and Flake8 compliance. Please note that this library does use eval to perform its expression processing.

Quick Start

Install Formatizer in your virtualenv as follows:

pip install formatizer

And now, go ahead and use the f function similarly to PEP 498:

from __future__ import print_function
from formatizer import f

GREETING = 'hi'

def main():
    name = 'Fotis'
    print(f('My name is {name}, I say {GREETING} and 1 + 2 is {1 + 2}'))

if __name__ == '__main__':
    main()

All local and global variables will be recognised by the f function and complete Python expressions are also allowed between the braces much like Python 3.6.
