Python Tuple Operations

In Python,there are 5 basic operations: finding length, concatenation, repetition, membership and iteration operations can be performed on any sequence may be it is a string, list, tuple or a dictionary.

To find length of a tuple, we can use len() function. This returns the number of elements in the tuple.

student = (30, 'Abhinav Siddarth', 74,85,56,52,36)

len(student)

We can concatenate or join two tuples and store the result in a new tuple. For example, the student paid a fees of Rs. 25,000.00 every year for 4 terms, then we can create a 'fees' tuple as:

fees = (25000.00,)*4 #repeat the tuple elements for 4 times.

print(fees)

Difference b/w fees = (25000.00,)*4 and fees = (25000.00)*4

Now, we can concatenate the 'student' and 'fees' tuples together to form a new tuple 'student1' as:

student1 = student+fees

print(student1)

Membership in Tuple

name='Abhinav Siddarth'

name in student1


Functions to Process Tuples

Function Example Description
len() len(tpl) Returns the number of elements in the tuple.
min()min(tpl)Returns the smallest element in the tuple.
max()max(tpl)Returns the biggest element in the tuple.
count()tpl.count(x)Returns how many times the element 'x' is found in tpl.
index()tpl.index(x)Returns the first occurrence of the element 'x' in tpl. Raises ValueError if 'x' is not found in the tuple.
sorted()sorted(tpl)Sorts the elements of the tuple into ascending order.sorted(tpl,reverse=True) will sort in reverse order.
