Tuples in Python
Tuple Basics
Tuples are immutable data structures in Python, meaning their elements cannot be modified after creation. Tuples are defined using parentheses () and can contain elements of different data types. Unlike lists, tuples do not support item assignment, as they are immutable.
Tuple Operations
Accessing elements in a tuple is done using indexing, similar to lists. Tuples do not have methods like append() or insert() to modify their contents. Tuples can be concatenated using the + operator to create a new tuple. Tuples can be repeated using the * operator.
Tuple Unpacking
Tuple unpacking allows you to assign multiple variables at once from the elements of a tuple. This is done using the * operator to capture the remaining elements in a list.
Examples
## Creating a tuple T = ('Amsterdam', 'Paris', 'Karachi') ## Attempting to modify a tuple ## element T[1] = 'Zurich' # TypeError: 'tuple' object does not support item assignment ## Creating a list and converting it to ## a tuple cities = ['Berlin', 'Lahore', 'Paris', 'Karachi', 'Mumbai'] R = tuple(cities) print(R) # Output: ('Berlin', 'Lahore', 'Paris', 'Karachi', 'Mumbai') ## Concatenating and repeating ## tuples W = ('Berlin', 'Amsterdam', 'Zurich', 'Karachi', 'Mumbai') T = W + ('Dhaka',) print(T) # Output: ('Berlin', 'Amsterdam', 'Zurich', 'Karachi', 'Mumbai', 'Dhaka') T = T * 5 print(T) # Output: ('Berlin', 'Amsterdam', 'Zurich', 'Karachi', 'Mumbai', 'Dhaka', 'Berlin', 'Amsterdam', 'Zurich', 'Karachi', 'Mumbai', 'Dhaka', 'Berlin', 'Amsterdam', 'Zurich', 'Karachi', 'Mumbai', 'Dhaka', 'Berlin', 'Amsterdam', 'Zurich', 'Karachi', 'Mumbai', 'Dhaka', 'Berlin', 'Amsterdam', 'Zurich', 'Karachi', 'Mumbai', 'Dhaka') ## Tuple unpacking Regions = ('South Asia', 'Central Asia', 'Middle East', 'South East Asia') SA, CA, *MS = Regions print(SA) # Output: South Asia print(CA) # Output: Central Asia print(MS) # Output: ['Middle East', 'South East Asia'] ``` ## Data Types in Tuples Tuples can contain elements of different data types, such as strings, integers, and floats. python a = 'String' b = 18 c = 18. ## Membership Testing You can use the in operator to check if an element is present in a tuple. ```python if 'Karachi' in T: print('Yes') else: print('No') if 'Kabul' in T: print('Yes') else: print('No') ```
