Tuple Functions In Python

 A tuple is a sequence of inflexible Python objects. Tuples are sequences, just like lists. The main difference between the tuples and the lists is that the tuples can not be changed unlike lists. Tuples use hiatuses, whereas lists use square classes.

Creating a tuple functions in python is as simple as putting different comma- separated values. Voluntarily, you can put these comma- separated values between hiatuses also. For illustration −

tup1 = ('physics', 'chemistry', 1997, 2000)

tup2 = (1, 2, 3, 4, 5 )

tup3 = "a", "b", "c", "d"

The empty tuple is written as two parentheses containing nothing −

tup1 = ();

To write a tuple containing a single value you have to include a comma, even though there is only one value −

tup1 = (50,)

Streamlining Tuples

Tuples are inflexible, which means you can not modernize or change the values of tuple rudiments. You're suitable to take portions of the being tuples to produce new tuples as the following illustration demonstrates −

#!/usr/bin/python3

tup1 = (12, 34.56)
tup2 = ('abc', 'xyz')

# Following action is not valid for tuples
# tup1[0] = 100;

# So let's create a new tuple as follows
tup3 = tup1 + tup2
print (tup3)

When the above code is executed, it produces the following result −

(12, 34.56, 'abc', 'xyz')

Like string indices, tuple indices start at 0, and they can be sliced, concatenated, and so on.

To pierce values in tuple, use the square classes for slicing along with the indicator or indicators to gain the value available at that indicator. For illustration −

#!/usr/bin/python3

tup1 = ('physics', 'chemistry', 1997, 2000)
tup2 = (1, 2, 3, 4, 5, 6, 7 )

print ("tup1[0]: ", tup1[0])
print ("tup2[1:5]: ", tup2[1:5])

When the above code is executed, it produces the following result −

tup1[0]:  physics
tup2[1:5]:  (2, 3, 4, 5)
