Convert tuple to float value in Python

When it is required to convert a tuple to a float value, the 'join' method, 'float' method, 'str' method and generator expression can be used.

Generator is a simple way of creating iterators. It automatically implements a class with '__iter__()' and '__next__()' methods and keeps track of the internal states, as well as raises 'StopIteration' exception when no values are present that could be returned.

The 'float' method converts a given element to float data type.

The 'str' method converts the given element into string data type.

Below is a demonstration of the same −

Example

Live Demo

my_tuple_1 = ( 7, 8)

print ("The first tuple is : " )
print(my_tuple_1)

my_result = float('.'.join(str(elem) for elem in my_tuple_1))

print("After converting the tuple to float, the tuple is : ")
print(my_result)

Output

The first tuple is :
(7, 8)
After converting the tuple to float, the tuple is :
7.8

Explanation

• A tuple is defined and is displayed on the console.
• The '.' operator and 'join' method is used to join the two elements in the tuple as a decimal number.
• This result is assigned to a variable.
• It is displayed as output on the console.
