Lists
The list is Python's most-used data structure — an ordered, mutable (changeable) collection that can hold items of any type, and grow or shrink as needed. Lists are central to almost every real Python program.
💡 Key insight
Unlike a C array, a Python list can mix types and change size at any point during the program.
Syntax
syntax
myList = [item1, item2, item3]
myList.append(item)
myList.remove(item)
myList[index]
myList[start:end]Example
.append() adds to the end, .remove() deletes the first matching item, and slicing [1:3] returns items at index 1 and 2 (not 3).
py
fruits = ["apple", "banana", "cherry"]
fruits.append("mango")
fruits.remove("banana")
print(fruits)
print("First:", fruits[0])
print("Slice:", fruits[1:3])output['apple', 'cherry', 'mango']
First: apple
Slice: ['cherry', 'mango']
