You can append the elements of one list to another with the "+=" operator. Note that the "+" operator creates a new list.
a = [1, 2, 3]
b = [10, 20]
a = a + b # Create a new list a+b and assign back to a.
print a
# [1, 2, 3, 10, 20]
# Equivalently:
a = [1, 2, 3]
b = [10, 20]
a += b
print a
# [1, 2, 3, 10, 20]
If you want to append the lists and keep them as lists, then try:
result = []
result.append(a)
result.append(b)
print result
# [[1, 2, 3], [10, 20]]

Apart from + operator there's another way to do the same i.e. extend()
a = [1, 2, 3]
b = [10, 20]
a.append(b) # Output: [1, 2, 3, [10, 20]]
a.extend(b) # Output: [1, 2, 3, 10, 20]
You can use these 2 functions for manipulating a list as per your requirement.

I want to make a program which takes 3 inputs and prints them at last. But I don't know how to make it.
PSEUDO-CODE:
id = 0
ARRAY id_list
ARRAY name_list
WHILE id < 3 {
INPUT name
APPEND name TO ARRAY name_list
id += 1
APPEND id TO ARRAY id_list
WHILE id == 3 {
PRINT (ARRAY ELEMENT id_list[0] and ARRAY ELEMENT name_list[0])
PRINT (ARRAY ELEMENT id_list[0] and ARRAY ELEMENT name_list[1])
PRINT (ARRAY ELEMENT id_list[0] and ARRAY ELEMENT name_list[2])
BREAK

So if I have
x = [1, 2, 3] then x.append(4) will be [1, 2, 3, 4]
However, the code itself is unaffected by the code. So that's what I'm looking for right now. Possible how to write to an array in another file.
THANKS!

x.append() will modify the list, I don't understand what you mean by "code itseld is unaffected"

Technically these are lists, not arrays (might lead to confusion), but I digress. So if I'm reading this correctly, you want to modify code in another file. You... probably shouldn't, as self-modifying code is rarely, if ever, a good idea. Instead, if you want persistent data, use something like a JSON file and store changes to that.
