l0n0lc 0.8.1

一个将python函数翻译为c++函数并运行的jit编译器

将python函数翻译为c++函数并运行

1. 安装

pip install l0n0lc

2. 运行hello_world.py

uv run tests/hello_world.py
# 输入: b'1\n2\n100\n101\n'

输出map: 
c 3 
a 1 
b 2 
输出list: 
0 134 
1 3 
2 2 
Hello World 13 3 
test_other_fn 10 
test编译的函数 39 
请输入>>>输入的 1 小于等于100 
请输入>>>输入的 2 小于等于100 
请输入>>>输入的 100 小于等于100 
请输入>>>结果: 241

3. 查看输出文件
