Two variables, x and y, supposedly hold strings of digits. write code that converts these to integers and assigns a variable z the sum of these two integers. make sure that if either x and y has bad data (that is, not a string of digits), z will be assigned the value of -1.

# string of digits

x = '456'

# string of digits

y = '789'

# check whether the variable x and y contains integer values or not

if(str.isdigit(x) and str.isdigit(y)):

     # convert the x value into integer

     tmpX = int(x)

     # convert the y value into integer

     tmpY = int(y)

     # sum of x and y

      z = tmpX + tmpY

# If x and y contains bad data

else:

      # assign value of z as "-1"

      z = -1;

      print('Not a string of digits')

#Display the result on the screen

print('Sum is',z)

Variable:

char: Character data type, example Z

int: numbers or integers, example 29

float: decimal number, example 2.1

double: decimal number too, but the capacity is bigger, for example, 2.1

String: a collection of characters that make up the text, for example, Hello World!

boolean: data types that are only true and false
