问题描述

当我运行此代码时,它要求我输入。但是,例如y,当我输入时,它给了我一个“objectnotfound 错误”,当我输入时h,它给了我一些比整个代码更长的列表。

我尝试将此代码发送给 Python Discord频道中的其他人,并且似乎对他们有用。

def average() -> float:
    nums = []
    while True:
        try:
            nums.append(float(input('')))
        except ValueError:
            return sum(nums) / len(nums)

当我输入y

PS C:\Users\NPC> 7
7
PS C:\Users\NPC> 5
5
PS C:\Users\NPC> 1
1
PS C:\Users\NPC> 51.56
51,56
PS C:\Users\NPC> y
y : The term 'y' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

当我输入h

我在 32 位 Windows 10 Pro 系统上使用最新的 32 位版本的 Visual Studio Code。我还在 Python IDLE中尝试了该代码,但这似乎也不起作用。

解决方案


您正在定义一个函数但没有调用它,因此当您运行代码时,它会在您输入任何内容之前完成运行。您的输入将直接发送到 PowerShell,而不是您的程序。

将此添加到脚本的底部:

average()

正如其他人指出的那样,在您的except分支中,您return的结果而不是结果print。你可能想print(sum(nums) / len(nums))改为。

我还强烈建议添加一个文本提示,以便更轻松地区分您的程序和您的 shell,例如

float(input('Please enter a number: '))
