Python Day 1: Data Types



Complete the code in the editor below. The variables i, d and s are already declared and initialized for you. You must:

1. Declare 3 variables: one of type int, one of type double, and one of type String.
2. Read 3 lines of input from stdin (according to the sequence given in the Input Format section below) and initialize your variables.
3. Use the + operator to perform the following operations:

a. Print the sum of i plus your int variable on a new line.
b. Print the sum of d plus your double variable to a scale of one decimal place on a new line.
c. Concatenate s with the string you read as input and print the result on a new line.



  1. i = 4
  2. d = 4.0
  3. s = 'HackerRank '
  4. # Declare second integer, double, and String variables.
  5. a = int(input())
  6. b = float(input())
  7. c = str(input())
  8. # Read and save an integer, double, and String to your variables.
  9. # Print the sum of both integer variables on a new line.
  10. print(i+a)
  11. # Print the sum of the double variables on a new line.
  12. print(d+b)
  13. # Concatenate and print the String variables on a new line
  14. print(s+c)
  15. # The 's' variable above should be printed first.
