I need your help with the next problem, i need that a python recieve an string "EEEEDDSGES" and the output would by the sum of charactes that repeat in line, E 4 D 2 S 1 G 1 E 1 S 1

my code is the next,

diccionario = {}
contador = 0
for palabra in cadena:

    if palabra.upper() in diccionario:
        diccionario[palabra.upper()]  = 1
    else:
        diccionario[palabra.upper()] = 1
for palabra in diccionario:
    frecuencia = diccionario[palabra]
    print(palabra, end=" ")
    print(frecuencia) ```

the output is ,

S,S,d,f,s
S 1
S 2
d 3
f 4
s 5

Try itertools.groupby:

from itertools import groupby

s = "EEEEDDSGES"

for v, g in groupby(s):
    print(v, sum(1 for _ in g))

Prints:

E 4
D 2
S 1
G 1
E 1
S 1

I'm sorry I don't understand what this language is, but I guess I understand what you are trying to do. I have changed the variable names for my comprehension.

s="EEEEDDSGES"

letters={}

for i in s:
  i=i.upper()
  try:
    letters[i] =1
  except(KeyError):
    letters.update({i:1})
    
for i in letters: print(f"{i}: {letters[i]}", end=" ")
