[英]Why doesn't my code dont work on my pc, but does on others?
当我运行此代码时,它会要求我输入。 但是当我输入例如y
,它给了我一个 objectnotfound 错误,当我输入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 中的其他人,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.

我在 32 位 Windows 10 Pro 上使用最新的 32 位版本的 Visual Studio Code。 我也在 Python IDLE 中尝试了该代码,这似乎也不起作用。
您正在定义一个函数而不是调用它,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
结果而不是print
它。 你可能想print(sum(nums) / len(nums))
代替。
我还强烈建议添加一个文本提示来更容易地区分你的程序和你的 shell,例如
float(input('Please enter a number: '))
