Question

classes = input ("what class are you in ? class1, class2 or class 3? ")
if classes == ("class1"):
students = input (str("how many students are in your class "))
while int(students)>int(student):
name = input ("what is your name ")
score = input ("what is your score ")
student = student + 1
name_arr = [] 
name_arr.append(name)
name_arr.append(score)
print(name_arr)



elif classes == ("class2"):
students = input (str("how many students are in your class "))
while int(students)>int(student):
    student = student + 1
    name1 = input ("what is your name ")
    score1 = input ("what is your score ")
     name_arr = [] 
    name_arr.append(name)
    name_arr.append(score)
    print(name_arr)

    elif classes == ("class3"):
students = input (str("how many students are in your class "))
while int(students)>int(student):
    student = student + 1
    name2 = input ("what is your name ")
    score2 = input ("what is your score ")
     name_arr = [] 
    name_arr.append(name)
    name_arr.append(score)
    print(name_arr)

当我运行代码时，名称和分数逐个打印而不是一个大数组！[在此输入图像描述] [1]

我需要将所有名称和所有分数放在一个大数组而不是一个数组上

Answer 1

您需要在循环之外初始化数组：

name_arr = [] 
while int(students)>int(student):
    name = input ("what is your name ")
    score = input ("what is your score ")
    student = student + 1

    name_arr.append(name)
    name_arr.append(score)
    print(name_arr)

否则你只需将它设置回每个循环的空列表。

我认为这会对你有帮助

classes = input ("what class are you in ? class1, class2 or class 3? ")
MAIN = []
if classes == "class1":
    students = input (str("how many students are in your class "))
    student=0
    while int(students)>int(student):
        name = input ("what is your name ")
        score = input ("what is your score ")
        student = student + 1
        MAIN.append(name)
        MAIN.append(score)

elif classes == "class2":
    students = input (str("how many students are in your class "))
    student=0
    while int(students)>int(student):
        student = student + 1
        name1 = input ("what is your name ")
        score1 = input ("what is your score ")
        MAIN.append(name1)
        MAIN.append(score1)

elif classes == ("class3"):
    student=0
    students = input (str("how many students are in your class "))
    while int(students)>int(student):
        student = student + 1
        name2 = input ("what is your name ")
        score2 = input ("what is your score ")
        MAIN.append(name2)
        MAIN.append(score2)

将我的所有分数和名字放在一个大阵列中
