创建python列表并在输入字段中显示列表项
创建python列表并在输入字段中显示列表项
提问于 2020-06-16 04:35:43
你好，我是这里的编码新手(教科书第5章)，我想输入x的学生数量和每个学生的分数。最终，我会计算出每个学生的平均成绩，但现在我正为输入而苦苦挣扎。
number_students = int(input("Number of Students: ")) #get number of students
number_grades = int(input ("How many grades per student: ")) #get number of grades per student
student_list = [] #create empty student list
student_grade = [] #create empty grade list
for num in range(number_students):
student_list.append(input("Enter Student Name: ")) #create an array based on number of students
for num in range (number_grades):
student_grade.append(int(input("Enter grade for #enter student name here# "))) #create an array based on number of grades ```我无法在student_grade输入字段中显示学生的名字，其次，是否有更好的方法使成绩列表与正确的学生相对应，而不是有一个非常长的成绩列表？也许每个学生的名字条目都是一个列表，然后将分数列表嵌入其中？

您可以使用python字典：
number_students = int(input("Number of Students: ")) #get number of students
number_grades = int(input ("How many grades per student: ")) #get number of grades per student
student_list = {} #create empty student dictionary
for num in range(number_students):
name = input("Enter Student Name: ")
student_list[name] = []
for num in range(number_grades):
grade = input(f"Enter grade for {name} ")
student_list[name] += [grade]输出：
Number of Students: 3
How many grades per student: 2
Enter Student Name: Johnny
Enter grade for Johnny 80
Enter grade for Johnny 92
Enter Student Name: Manny
Enter grade for Manny 78
Enter grade for Manny 59
Enter Student Name: Sarah
Enter grade for Sarah 98
Enter grade for Sarah 89
{'Johnny': ['80', '92'], 'Manny': ['78', '59'], 'Sarah': ['98', '89']}Stack Overflow用户

一种方法是使用字典列表：
number_students = int(input("Number of Students: "))
number_grades = int(input ("How many grades per student: "))
for num in range(number_students):
student_name = input("Enter Student Name: ")
student_grades = []
for num in range(number_grades):
student_grades.append(int(input(f"Enter {student_name}'s grade")))
student_list.append({
'student': student_name,
'grades': student_grades
})
print(student_list[0]['student'])
print(student_list[0]['grades'])页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
