Lists

Syntax:

fav_number=[prime_number, "PI", 3.1415]

Accesing the list items

print(fav_number[1]) #gives PI
print(fav_number[-1]) #gives 3.1415
print(fav_number)

Altering the data

fav_number[0]="12357.." #changes prime_number to 12357..
fav_number.append("Eulers number") #adds Eulers number to the list, can only add one data
fav_number.extend(["Eulers number", 0, 69]) #adds multiple data at the end

Lists inside a list

fruits=["Apple", "Mango", "Strawberry", "Banana"]
vegetables=["Spinach", "Tomatoes", "Celery", "Potatoes"]
fruits_veggies=[fruits, vegetables]

Notes:

• a single list can contain different data types
• to add something in a list, either use list_name+= data OR list_name.append(data)
