类型错误：无法在第10行连接'str'和'float'对象

Question

print("\n\nThis is a basic program to find the letter grade for a student.")
student = input("What is the students name? : ")
test1 = input("What is the first test grade " + student.capitalize() + " recieved? : ")
test2 = input("What is the second test grade " + student.capitalize() + " recieved? : ")
test3 = input("What is the third test grade " + student.capitalize() + " recieved? : ")
averageTest = (int(test1) + int(test2) + int(test3))
print(student.capitalize() + " recieved an average test grade of " + ((averageTest) / 3))

我正在写一个基本等级的计算器程序，不能解决这个问题

TypeError: cannot concatenate 'str' and 'float' objects

我还有很多东西要写，我被困在这条线上 print(student.capitalize() + " recieved an average test grade of " + ((averageTest) / 3))

Answer 1

不能添加字符串和数字（float）。相反，在使用另一个字符串添加浮点数之前，请先将其转换为字符串。你可以用

str(x)

在您的情况下，这将是：

^{pr2}$
