How do I parse a string to a float or int in Python? 22 answers

Your line should be pi_float = float(pi_string)

float(pi_string) is a float value, you can not assign to it, because it is not a variable.

如果pi_string = "3.1415926" float()方法将为您执行此操作。

>>>pi_float = float(pi_string)
>>>type(pi_float)
<class 'float'>
