如何在Python中打印方法的返回值？ [英] How to print return value of method in Python?

问题描述

class Queue():
    def __init__(self):
        self.items = []

    def isEmpty(self):
        return self.items == []

    def Enqueue(self,item):
        return self.items.insert(0, item)

    def Size(self):
        return len(self.items)

    def Dequeue(self):
        return self.items.pop()

Q = Queue()    
def Hotpot(namelist,num):

    for name in namelist:
        Q.Enqueue(name)

    while Q.Size() > 1:
        for i in range(num):
           Q.Enqueue(Q.Dequeue())
        Q.Dequeue()
    return Q.Dequeue() # I would like to print and see what is getting removed, I tried with x = Q.Dequeue(), print x and print Q.Dequeue() but im getting "None"



print Hotpot(['A','B','C','D','E','F'],7)

Hi Team，
我正在尝试检查Queue的代码，这里我想打印哪个值正在删除每个循环。虽然打印我没有任何东西，但请帮助我为我的期望做些什么改变。

Hi Team, I am trying above code for checking Queue, here I would like to print which value is removing each cycle. While printing I am getting none oly, please help me what changes I have to do for my expectation.

推荐答案

如果你想要知道要返回什么，你需要在本地保存，打印你保存的内容，然后返回你保存的内容。类似于：

If you want to know what's goingto be returned, you need to save it locally, print what you saved, then return what you saved. Something like:

    x = Q.Dequeue()
    print(x)
    return x
