How to replace an element of a nested list by the values of a dictionary, if the key matches?

Question

I have a list:

lst = [[1,0],[20,0],[21,1],[22,3],[24,2]]

Also a dict

dct = {0:"Balco",1:"Greg",2:"Palm",3:"New"}

I want to replace the 2nd element of nested list with the values that match from the dictionary.

So, the expected new list will be:

lst = [[1,"Balco"],[20,"Balco"],[21,"Greg"],[22,"New"],[24,"Palm"]]

Answer 1

A simple for loop should work:

for item in lst:
    item[1] = dct[item[1]]

print(lst)

Or, using list comprehension for a one-liner:

result = [[item[0], dct[item[1]]] for item in lst]
