1.  **print**

print('here')
    # 可以发现某段逻辑是否执行
    # 打印出变量的内容

1.  **assert**

assert false, 'blabla'
    # 如果条件不成立，则打印出 'blabla' 并抛出AssertionError异常

1.  **debugger**

可以通过 pdb、IDE等工具进行调试
    调试的具体方法这里不展开
    python中有两个内置方法在这里也很有帮助

**vars**

vars(), 同locals()
    vars(obj), 输出 obj.__dict__

**locals**

执行locals()之后, 返回一个字典, 包含(current scope)当前范围下的局部变量

**globals**

执行globals()之后, 返回一个字典, 包含(current scope)当前范围下的全局变量
