Python Tuples
A tuple is a Python data type that stores multiple values, separated by commas and enclosed in parentheses. While tuples may seem similar to lists, they have key differences.
The main distinction is mutability: lists can be modified, but tuples cannot. For example, the .extend() method works on lists but not on tuples. Once created, a tuple's contents cannot be changed without creating a new one.
Tuples are also faster and more memory-efficient than lists, making them a good choice for storing fixed or sensitive data.
# Create tuple US_Info = ("USA", 9629091, 331002651) # Printing tuple print(type(US_Info))
Note
You can also transform an iterable object into a tuple with the
tuple()function.
# Create a list list_variable = [1, 2, 3] # Convert it into a tuple tuple_variable = tuple(list_variable) # Print the type of the converted variable print(type(tuple_variable))
Everything was clear?
