Python3 has built-in functions

This section describes the built-in functions in Python3.

Python debugging method

1、print

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

2、assert

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

3、debugger

Debugging can be done with tools such as pdb and IDE.

The specific method of debugging is not expanded here.

There are two built-in methods in Python that are also helpful here:

• locals: After executing locals(), returns a dictionary that contains local variables under the current scope.
• Globals: After performing globals(), returns a dictionary that contains global variables under the current scope.
