List2= [“123 Apple”, “123 Plane”, “122 Pizza” ]

Answer 1

I would merge the two lists. You can use + to do it:

a = [1,2,3]
b = [4,5,6]
c = a + b
print(c) #[1,2,3,4,5,6]

Answer 2

- Create an empty dictionary first

- Run a for loop on the combined list of the two

- For each element do
- Slice first 3 character of the element and check if that slice exists as key in dictionary

- If it does, update dictionary item by adding a slice of the element (starting from 4th character) to the item value

- Otherwise create a new dictionary item with 3 first characters slice as item key, and rest of the element (starting from 4th character) as the item value

* You can also opt to split the element rather than using slicing, if you are sure that each splitted element will result only in two chunks.

List1 = [ "123 Kevin", "122 Mark" ]
List2 = [ "123 Apple", "123 Plane", "122 Pizza" ]
mydict = {}
for el in List1 + List2:
dkey = el[ : 3 ]
if dkey in mydict:
mydict[ dkey ] += el[ 3 : ]
else:
mydict[ dkey ] = el[ 3 : ]

for k, v in mydict.items():
print( f"{k} {v}")
