我有一个“bad token”错误，谁能告诉我为什么？ （代码）

Question

Ideal= int(input("What grade do you want on your next assignment?"))

Current= int(input("What is your current grade in the class?"))
weight = int (input("What is the weight of the assignment (how much of your grade is it worth)?"))
print Ideal

print Current

print weight

Final_grade = Ideal − (( 1 − weight ) * Current)* weight

print "You will need to get a" , Final_grade , "on your next assignment to recieve a" , Current , "in this class"

Answer 1

错误是因为您的−字符实际上不是减号字符。 您可能从实际上没有减号的地方复制了这段代码。

这是正确的减号： -

尝试这个：

Ideal= int(input("What grade do you want on your next assignment?"))

Current= int(input("What is your current grade in the class?"))
weight = int (input("What is the weight of the assignment (how much of your grade is it worth)?"))
print Ideal

print Current

print weight

Final_grade = Ideal - (( 1 - weight ) * Current)* weight

print "You will need to get a" , Final_grade , "on your next assignment to recieve a" , Current , "in this class"

Output：

What grade do you want on your next assignment?5
What is your current grade in the class?4
What is the weight of the assignment (how much of your grade is it worth)?4
5
4
4
You will need to get a 53 on your next assignment to recieve a 4 in this class
