Python Lists
In Python, a list is like a smart container that can hold many items at once — numbers, text, or even a mix of both. Lists are:
Ordered: Items stay in the same sequence you put them.
Changeable: You can update, add, or remove items after the list is created.
Enclosed in square brackets: Use
[]and separate items with commas.
Example 1:
numbers = [4, 7, 7, 1, 3, 9]
colors = ["Orange", "Purple", "Teal"]
print(numbers)
print(colors)
Output:
[4, 7, 7, 1, 3, 9]
['Orange', 'Purple', 'Teal']
You can repeat values, and Python will store them exactly as given.
Example 2:
A single list can hold different types of values — strings, numbers, floats, or even booleans.
student_info = ["Areeba", 20, "BS Computer Science", 3.65]
print(student_info)
Output:
['Areeba', 20, 'BS Computer Science', 3.65]
Why Lists Are Useful?
Think of a list like a backpack. You can put:
Books (strings),
Water bottle (float),
ID card (number),
And still add more things later!
Lists are essential for managing related data — especially when you want to loop, sort, or filter information.
