Convert python scripts into oneliner expression.

Convert python scripts into oneliner expression.

Usage

python3 -m oneliner [input file] -o [output file]

Or use python3 -m oneliner -h for help.

Example

InputFile:

import random
y,h=0,2
msg='hello_world'
while y<h*2:
    for x in range(len(msg)+2):
        print(random.choice('/\\'),end='')
    y+=1
    if y==h:
        print('\n %s '%msg)
    else:
        print('')

OutputFile:

[(importlib := __import__('importlib')), (itertools := __import__('itertools')), (random := importlib.import_module('random')), (__ol_assign_qqaleuwbod := (0, 2)), (y := __ol_assign_qqaleuwbod[0]), (h := __ol_assign_qqaleuwbod[1]), (msg := 'hello_world'), [[[print(random.choice('/\\'), end='') for x in range(len(msg) + 2)], y.__iadd__(1) if hasattr(y, '__iadd__') else (y := (y + 1)), print('\n %s ' % msg) if y == h else print('')] for _ in itertools.takewhile(lambda _: y < h * 2, itertools.count())]]

Install

pip install Oneliner-Py

Or
