Here it is:

from itertools import permutations
import re

caracteres = ['A', 'B', 'C', 'D']

for i in permutations(caracteres,2): # 2 elementos
    i = re.sub(r'\W',"",str(i)) # Retirando outros caracteres que não sejam letras
    print(i)

print()
for i in permutations(caracteres,3): # 3 Elementos
    i = re.sub(r'\W',"",str(i))
    print(i)

print()
for i in permutations(caracteres,4): # 4 Elementos
    i = re.sub(r'\W',"",str(i))
    print(i)
