Add item to existing list and be able to print list for each item in range in new line

Question

Hi am new just started Computer Science at London Met we have programming in Python. In this code am trying to add items to already existing appended list list.append([student_name, student_age, student_sex]) from user input student_grade. How can i do this for each item in range. SO next time i print student_grade will be added to at the end of statement in form {each_item[3]} and 3 in the case will be student_grade ?

thanks in advance

from io import StringIO
import sys

number_student = int(input("How many students You want to add: "))

list = []
for i in range(0, number_student):
student_name = input("Whats Your name student? ")
student_age = input("Whats Your age student? ")
student_sex = input("Female or male? ")
list.append([student_name, student_age, student_sex])

comment withhash  student_1 = (student_name, student_age + "years old", student_sex)

for each_item in list:
print(f"Student name is {each_item[0]}, you are {each_item[1]} years old and you are {each_item[2]}")

student_grade = input("Add student grade: ")
list.extend(["student_grade"])
#list.extend([student_grade])

for each_item in list:
print(f"Student name is {each_item[0]}, you are {each_item[1]} years old and you are {each_item[2]}, and your grades are", student_grade)

Answer 1

You shouldn't be adding student_grade to list, you should be adding it to each_item, the list for the current student.

Then when printing the grade, you use each_item[3] to get it.

Also, don't use list as a variable name, because it's a built-in function. I've renamed it to student_list below.

number_student = int(input("How many students You want to add: "))

student_list = []
for i in range(0, number_student):
    student_name = input("Whats Your name student? ")
    student_age = input("Whats Your age student? ")
    student_sex = input("Female or male? ")
    student_list.append([student_name, student_age, student_sex])

#student_1 = (student_name, student_age + "years old", student_sex)

for each_item in student_list:
    print(f"Student name is {each_item[0]}, you are {each_item[1]} years old and you are {each_item[2]}")

    student_grade = input("Add student grade: ")
    each_item.append(student_grade)

for each_item in student_list:
    print(f"Student name is {each_item[0]}, you are {each_item[1]} years old and you are {each_item[2]}, and your grades are {each_item[3]}")
