Question

grade = 0.0
grade = input("Please enter your gpa")
    def grade_give(grade):
        if grade > 0.9:
            print("A")  
        elif grade > 0.8 and grade < 0.9 :
            print("B")
        elif grade >0.7 and grade < 0.8:
            print ("C")
        elif grade >0.6 and grade <0.7:
            print ("D")
        elif grade >0.5 and grade <0.6:
            print ("E")
        elif grade >0.4 and grade <0.3:
           print ("F")
        else:
           print("Bad score")

grade_give(grade)

出现的错误是grade_give中的文件“/Users/pradyu/Desktop/py.py/function.py”，第4行如果等级＆gt; 0.9： TypeError：'＆gt;' 'str'和'float'的实例之间不支持

Answer 1

输入的输入是一个字符串。将其转换为浮动。

FILE * binfile = fopen("b2.bin", "rb");

或在函数

中执行此操作

grade = input("Please enter your gpa")
grade = float(grade)
#carry on

关于python if-else语句的这个简单代码是错误的吗？
