Python Tuples, Operations

To get number of specific elements (by value), we can use count() function:

tuple_names = ("Samantha", "Madonna", "Michael")

result = tuple_names.count("Samantha")

print("Number of Samantha's: ", result)

Result: 

Number of Samantha's:  1
>>> 

We can locate position of specific element (by value) using index() function:

tuple_names = ("Samantha", "Madonna", "Michael")

pos = tuple_names.index("Madonna")

print(pos)

Result: 

1
>>> 

If we grab value from keyboard, it's easy to find first location, and total number of elements:

tuple_names = ("Samantha", "Madonna", "Michael")

x = input("Enter name to check: ")

print("Number of them: ", tuple_names.count(x))
print("First occurence at position: ", tuple_names.index(x))

Result: 

Enter name to check: Madonna
Number of them:  1
First occurence at position:  1
>>> 

Tuples are easy to work with.
