When i did number =3 and list=[string,0,[1+2+number],4.2] and print ([2]*[2]) then why there was an error

Question

It was the programm of python in topic of string.
number = 3
things = ["string", 0, [1+ 2+ number], 4.56]
print(things[1])
print(things[2])
print(things[2]*[2])

Answer 1

You can't multiply two lists.

print(things[2]) # [6] (list with one element)
print(things[2][0]*[2][0]) # = 6*6

Answer 2

Makes sure the second argument is also things[2] and not just [2]

Answer 3

I did not get, actually i have edited code and multiply [2]*[2] and i have changed [1,2,number] to [1+2+number].

Answer 4
