The code block creates a list of tuples which holds the name and Density values of materials. The program written in python 3 goes thus ;
name = input()
#accepts name input from user
name = [n for n in name.split()]
#split the inputs
density = input()
#accepts density inputs
density = [int(d) for d in density.split()]
#split the density inputs
currMat = list(zip(name, density))
#combines the inputs into a list of tuples
requestedMaterial = currMat
#assigns to another variable
print(requestedMaterial)
A sample run of the program is attached
