带字符串的for循环有什么问题？(What is wrong with this for loop with a string? [closed])

带字符串的for循环有什么问题？(What is wrong with this for loop with a string? [closed]) Start= 1 End= 10 change=0.5 for Start in range(Start,End,change) : print(Start)

这段代码有什么问题？ 我在学校工作，似乎无法使用字符串的for循环。

Start= 1 End= 10 change=0.5 for Start in range(Start,End,change) : print(Start)

What is wrong with this code? I was working at it in school and can't seem to use the for loop with a string.

最满意答案

Python range支持浮点increment ，因此错误：

DeprecationWarning: integer argument expected, got float

所以你在0.5的值需要是一个整数，你可以用数学来得到相同的输出

Start= 2 End= 21 change=1 for Start in range(Start,End,change) : print(Start*0.5)

Python range wont support floating point increment, Hence the error:

DeprecationWarning: integer argument expected, got float

So your value at 0.5 needs to be an integer, and you can use mathematics to still get same output

Start= 2 End= 21 change=1 for Start in range(Start,End,change) : print(Start*0.5)
