回答by Dean Fenster
Your line should be pi_float = float(pi_string)
你的线路应该是 pi_float = float(pi_string)
float(pi_string)
is a float value, you can not assign to it, because it is not a variable.
float(pi_string)
是一个浮点值,你不能赋值给它,因为它不是一个变量。

The method float()
will do this for you if pi_string = "3.1415926"
.
该方法float()
会为你如果做到这一点pi_string = "3.1415926"
。
>>>pi_float = float(pi_string)
>>>type(pi_float)
<class 'float'>
