I am learning to use python and there is one thing that I can not do, I want to make a loop for when I ask a question, just let me put one of these letters a, b, c, d, e that in the first run, after that ask me again which letter I want to choose, but now I can choose 5 more that is% a, b, c, d, e, f, g, h, i, j and in the next print 5 more letters and so on until I reach 25 letters.

I paste down what I have done, it works well, it does not let me put numbers or the other letters, the problem is when I put two letters (for example hj ) peta if you could help me or do it in some other way than I would like to thank you.

cuantas_frutas_coger = 5
letra = 97 #Es la letra a en ASCII
jugador = '1'
while not jugador.isalpha() or ord(jugador) > letra+cuantas_frutas_coger:
    print ('Elige una letra entre a y ', chr(letra+cuantas_frutas_coger))
    jugador = input('')

I do not know if I've explained myself well, it's a game in which you first have to take 5 letters, if you win there are 10, if you win again 15 and only that piece is missing. Thanks.

Regarding the reading of data, you can do one of these two things.

Take only the first letter of the player's response. So, if you write "aj", the "j" would be discarded:

while not jugador.isalpha() or ord(jugador) > letra+cuantas_frutas_coger:
    print ('Elige una letra entre a y ', chr(letra+cuantas_frutas_coger))
    jugador = input('')
    jugador = jugador[0]

Do not validate an entry that has several letters, and force the player to repeat the entry if he / she puts more than one:

while (len(jugador) > 1 or
       not jugador.isalpha() or
       ord(jugador) > letra+cuantas_frutas_coger):
    print ('Elige una letra entre a y ', chr(letra+cuantas_frutas_coger))
    jugador = input('')
    jugador = jugador[0]

As for how the game continues, it has not been clear to me. I suppose that this data entry should be part of another loop in which the variable cuantas_frutas_coger is incremented but I do not understand with what criteria. In any case, your question was limited to data entry, right?
