List- Basics

student_number = []
student_name ["mark","rob","Jessica"]

Index is used to access elements in a list
for example:
student_name[0] == "Mark"
student_name[1] == "rob"
student_name[-1]="Jessica"

Student_name[0] ="James"
student_name ["James","rob","Jessica"]

Add element to a list:
student_name.append("mark")
student_name ["James","rob","Jessica","mark"]

Checking element in list:
"mark" in student_name == True
