如何纠正未定义TypeError字符串

我们必须询问用户在一个月内使用了多少分钟，并将其乘以0.10，以获得他们在分钟上花费的时间。
代码：
mins = input("How many minutes have you used this month? ")
minsprice = float(mins)*0.10
print ("You have used",round(mins,2),"GBP worth of minutes this month.")它返回以下错误：
Traceback (most recent call last):
File "C:\Users\User\Downloads\assessment.py", line 23, in
print ("You have used",float(round(mins,2)),"GBP worth of minutes this month.")
TypeError: type str doesn't define __round__ methodStack Overflow用户

我想你打错了。你写mins。它应该是minsprice最后一行。这就是错误发生的原因。试试这个
mins = input("How many minutes have you used this month? ")
minsprice = float(mins)*0.10
print ("You have used",round(minsprice,2),"GBP worth of minutes this month.")页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
