3. 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 
测试所有操作: 
vector-> 0 = 2 
vector-> 1 = 13 
vv: 1 
测试while: 
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
