Creating and Indexing Lists

Creating and Indexing Lists

A list stores many values, in order, in one variable. It is written in square brackets, and the values can be of any type. Lists use the same indexing and slicing as strings, but unlike strings they are mutable: an element can be changed in place.

marks = [78, 91, 65, 88, 70]
print(marks[0], marks[-1])  # 78 70
marks[2] = 68               # change the third mark
print(marks[1:3])           # [91, 68]
print(len(marks), sum(marks), max(marks), min(marks))   # 5 395 91 68

To read a whole line of numbers into a list: nums = list(map(int, input().split())). A for loop visits every element: for m in marks:.

marks = list(map(int, input().split()))
total = 0
highest = 0
print("Total:", total)
print("Highest:", highest)
print(f"Average: {0:.2f}")
