[Tutor] updating a print statement

[Bryan Fodness]

for line in file('test.txt'):
    the_line = line.split()
    if the_line:
        if the_line[0] == 'Index':
            index = float(the_line[-1])
            print ("\rIndex = %.3f  ") %index,
raw_input("\nExit")
Here is my output,

Index = 0.000   Index = 0.400   Index = 0.800   Index = 1.000
