Tuples are immutable :

A tuple is a sequence of values. The values can be any type, and they are indexed by integers, so in that respect tuples are a lot like lists. The important difference is that tuples are immutable as well as a tuple is a collection which is ordered and unchangeable. In Python tuples are written with round brackets. For example : ("ayan","dev","apu","symul")

Creating and Accessing Values in Tuples :

Creating a tuple is as simple as putting different comma-separated values. Optionally you can put these comma-separated values between parentheses also. To access values in tuple, use the square brackets for slicing along with the index or indices to obtain value available at that index.

Example :

newtuple=("ayan","dev","apu","symul") print(newtuple) #print full tuple print(newtuple[1]) #print/return the item in position 1 (start with 0) input()

Output :

Note : Once a tuple is created, you cannot change its values. Tuples are unchangeable.

Loop Through a Tuple :

You can loop through the tuple items by using a for loop.

Example :

newtuple=("ayan","dev","apu","symul") for x in newtuple: print(x) #print the values one by one input()

Output :

Check if Item Exists :

To determine if a specified item is present in a tuple use the in keyword.

Example :

newtuple=("ayan","dev","apu","symul") if "dev" in newtuple: print("Yes, 'dev' is in the tuple") #Check if "dev" is present in the tuple input()

Output :

Tuples with methods :

python list have built-in methods, methods help us to manipulate tuple items.

Example :

newtuple=("ayan","dev","apu","symul") print(len(newtuple)) #Print the number of items in the tuple print(max(newtuple)) #Returns item from the tuple with max value print(min(newtuple)) #Returns item from the tuple with min value. input()

Output :

Tuples methods :

Python includes many built-in methods but here we just adding some of the following built-in methods to manipulate tuples :

• The len() method determine how many items a list has.
• The max() method returns item from the tuple with max value.
• The min() method returns item from the tuple with min value.
• The count() method returns the number of times a specified value occurs in a tuple.
• The index() method searches the tuple for a specified value and returns the position of where it was found.
