Overview
Python tuple items can be looped through and accessed using a for loop or while loop.
For Loop
my_tuple = ("Ferrari", "Maserati", "Alfa Romeo")
for x in my_tuple:
print(x)
Output:
Ferrari
Maserati
Alfa Romeo
For Loop Using Index Number
You can also loop through the tuple items by referring to their index number, using the range() and len() funtctions.
my_tuple = ("Ferrari", "Maserati", "Alfa Romeo")
for i in range(len(my_tuple)):
print(my_tuple[i])
Output:
Ferrari
Maserati
Alfa Romeo
Note
Arrays count starting from zero NOT one. So item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on.
While Loop
Use the len() function to determine the length of the tuple, then start at 0 and loop through the tuple items by referring to their indexes by increasing the index by 1 after each iteration.
my_tuple = ("Ferrari", "Maserati", "Alfa Romeo")
i = 0
while i < len(my_tuple):
print(my_tuple[i])
i = i + 1
Output:
Ferrari
Maserati
Alfa Romeo
Python Notes:
- The most recent major version of Python is Python 3; however, Python 2 is still in use and quite popular, although not being updated with anything other than security updates
- Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses
- Python relies on indentation, using whitespace to define scope, such as the scope of loops, functions, and classes; other programming languages often use curly-brackets for this purpose
- Python string methods return new values, and DO NOT change the original string
- Python tuples are unchangeable after created (their items CANNOT be changed or re-ordered at a later point)
- Python sets are unordered (may appear in random orders when called), unchangeable (the value of individual items cannot be changed after creation), and unindexed (items cannot be referred to by index or key)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
