Write a python program that asks the user to enter a stringcontaining numbers separated by commas, e.g., s = '1.23,2.4,3.123',Your program should then calculate and print the sum of the numbersentered. Hint: you need to iterate over the string searching forthe commas, i.e. their index. The first number is obtained byslicing between the start of the string and the index of the firstcomma. The second number is between the last comma and the nextone, and so on. For this program do not use the standard stringfunctions.
