Python can not concatenate a string and an integer. They are considered two separate types of object. "i"*20 concatenates strings (20 i's). "i" + 20 attempts to concatenate a string and an integer. To get that to work you would have to convert 20 to a string "i" + str(20).

"i" * 20 is multiplying the string "i" 20 times "i" + 20 doesn't work because "i" is a string and 20 is a int .. you can not concatenate a string with a int nor add a int (number) with a sting . you can "i" + "20" so it will print "i20" ..meaning the 20 ..must be with "" so it will become a string as well
