Question

我试图为我的最终项目使用GUI编写GPA计算器。我对其中的一些进行了编码，然后卡在其中。

import  math

x = int(input('How many courses are you taking this year?'))

marklst = []

i = 1

while i <= x:
    y = int(input('What is your mark for this class?'))
    marklst.append(y)
    i += 1

percentage_calculation = sum(marklst)/(x)

print(percentage_calculation)

for percentage_calculation in range(x,y):
    print('Your GPA is 1')

for percentage_calculation in range(w,z):
    print('Your GPA is 2')

for percentage_calculation in range(o,p):
    print('Your GPA is 3')

有没有一种更快的打印GPA的方法，而无需编写10行以进行（x，y）范围内的percent_calculation

我认为，只要将for更改为if，就可以正常工作。

如果您正在寻找一种较短的方法来代替此部分：

x = int(input('How many courses are you taking this year?'))

marklst = []

i = 1

while i <= x:
    y = int(input('What is your mark for this class?'))
    marklst.append(y)
    i += 1

您可以执行以下操作：

marklst = input("Please enter your marks for this year seperated by commas:")
# Let's suppose the user entered 5,4,3,5,4 which will give you a string
# Then you can split and cast them to ints
marklst = [int(mark) for mark in marklst.split(",")]

# Your percentage calculation will be 
percentage_calculation = sum(marklst)/(len(marklst))

我想您仍然必须具有if语句才能进行比较和打印。

在y行范围内为x加10的更快方法
