如何找到python方法所需的参数数量

Question

I want to find how many arguments required for any methods. In a general way.

For example:

import queue

data_queue = queue.PriorityQueue() 

Want to know how many arguments needed for 'data_queue'

Answer 1

As @jonrsharpe mentioned, call the help method. Just:

import queue

data_queue = queue.PriorityQueue() 

help(data_queue)
