I don't understand the 3rd and 5th line of this code, can someone help me out please?

Question

words = input()
inpt = words.split(" ")
a = []
for i in inpt:
a.append(len(i))
num = max(a)

for j in inpt:
if num == len(j):
print(j)

Answer 1

3rd line: a=[]

Here we are taking an empty list

5th line: a.append(len(i))
Here we are adding the length of i in the list (a).

Answer 2

Are we adding the length of I to the list? .What's the use of the "append"?

Answer 3

append is used to add the specific element in that list, you can refer to the links:

edit]: oops, I didn't answered your first question, yes we are adding the length of the i in the list (length of input).
