from itertools import combinations

lst = ["a" ,"b", "c"]
lengthOfStrings = 3
for i in combinations(lst, lengthOfStrings):
  print(i)

Here is what the above code is Doing:
1. We have a list of strings.
2. We want to find all the possible combinations of the strings in the list.
3. We want to find all the possible combinations of the strings in the list of length 3.
4. We use the itertools.combinations() function to find all the possible combinations of the strings in the list of length 3.
5. We print the combinations.
