OLG4P 0.1

Convert python script into python one-liner

One-Liner Generator for Python

A simple script that converts python scripts into one-liner.

Install

pip install OLG4P

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('')

Generated:

[(itertools := __import__('itertools')), (random := __import__('random')), [(__ol_assign_tmp_nxazjlgisn := (0, 2)), (y := __ol_assign_tmp_nxazjlgisn[0]), (h := __ol_assign_tmp_nxazjlgisn[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())]]

Limitation

This script requires python3.9+. Many statements are not convertable.
Here are the statements that have already been implemented.

statement	example
Expr	print((1+1)*2)
Assign	a=1 a,b=b,a
AugAssign	a*=1
If	if a==0: ... elif a>1: ... else: ...
For	for i in range(10): ... else: ...
While	while a<100: ... else: ...
Break	break
Continue	continue
Pass	while 1: pass
Import 1	import math import os,sys import numpy as np
FunctionDef	def func(a,*args): ...
Return	return None

Remarks:

1. 'from-import' is not implmented.

Dependencies

• CPython >= 3.9
