谁能告诉我我的代码有什么问题？我是新手，我不知道出了什么问题。 [英] Could anyone tell me what is wrong with my code? Im a newbie and I have no idea what is wrong.

问题描述

def cube(number):
    return number**3
    
def by_three(number):
    if number%3==0:
        cube()
        return cube.
    else:
        return False

我的尝试：



我需要创建一个多维给定数字的函数。然后我必须创建另一个名为by_three的函数，它检查它是否可被3整除。如果它是那么我必须通过第一个函数立方体，否则返回false。我是新手，几天前开始编码。我不知道我的代码有什么问题

What I have tried:

I need to create a function which cubes a given number. then i have to create another function called by_three which checks if its divisible by three. if it is then i have to cube it through the first function else return false. im a newbie and started coding just a couple of days ago.I have no idea what is wrong with my code

推荐答案

建议：按照教程学习python的基础知识。

您可能收到错误消息

Advice: follow tutorials to learn the basics of python.
You probably got error messages

def cube(number):
    return number**3
    
def by_three(number):
    if number%3==0:
        # you forgot to tell what you cube()
        cube()
        # here, cube is a variable that does not exist
        # the '.' at the end does not exist
        return cube.
    else:
        return False

有一个工具可以让你看到你的代码在做什么，它的名字是 debugger 。它也是一个很好的学习工具，因为它向你展示了现实，你可以看到哪种期望与现实相符。

当你不明白你的代码在做什么或为什么它做它做的时候，答案就是答案是调试器。

使用调试器查看代码正在执行的操作。只需设置断点并查看代码执行情况，调试器允许您逐行执行第1行并在执行时检查变量。



调试器 - 维基百科，免费的百科全书 [ ^ ]

27.3。 pdb - Python调试器 - Python 3.6.1文档 [ ^ ]

使用Python进行调试Python征服宇宙 [ ^ ]

pdb - 交互式调试器 - 本周的Python模块 [ ^ ]

调试器在这里显示你的内容代码正在做，你的任务是与它应该做的事情进行比较。

调试器中没有魔法，它没有发现错误，它只是帮助你。当代码没有达到预期的效果时，你就会接近一个错误。

There is a tool that allow you to see what your code is doing, its name is debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

Debugger - Wikipedia, the free encyclopedia[^]
27.3. pdb — The Python Debugger — Python 3.6.1 documentation[^]
Debugging in Python | Python Conquers The Universe[^]
pdb – Interactive Debugger - Python Module of the Week[^]
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
