python - Replace an item in a list based on user input -

-

i'm noob please excuse me.

there 3 lists

  1. a list of letters l = ['a','b','c','d','e']
  2. a list of numbers n = ['1','2','3','4','5']
  3. a list of number strings list = ['124','351']

these steps wish achieve

  1. request letter user e.g. a
  2. find letter in letter list l , record numerical position e.g. [0]
  3. use same numeric position in list of numbers n , record number that's there e.g. 1
  4. replace instances of number found in non-letter strings list e.g. ['124','351'] becomes ['a24','35a']
  5. ask user next letter until number strings become letters.

what have achieved far first 4 steps. after step 4 thought check if number strings still contained numbers , if go step 5. can't seem work out how code check if number strings contain more number. note: number list not limited numbers. contain math symbols e.g. + or -

l = ['a','b','c','d','e'] n = ['1','2','3','4','5'] list = ['124','351']  print ("enter letter")  # there number in list # if yes following else print list  # ask letter user letter = input ("enter letter: ")  # confirm whether letter correct or not if letter in l: # find position of letter in list     position = (l.index(letter)); # make variable called number value @ same position in n list     number = n[position]; # replace numbers in list letter entered     list = [item.replace(number, letter) item in list]; # print list numbers replaced     print (list, "\n");     print ("please guess again. \n");     letter = input ("enter letter now: ") # repeat until list contains letters else:     print ("that not correct");     print ("please guess again. \n");     letter = input ("enter letter now: ")

i hope ok. if need further please let me know

l = ['a','b','c','d','e'] n = ['1','2','3','4','5'] n_strings = ['124','351'] # don't use list variable name  while not all( x.isalpha() x in n_strings): # keep going until alpha chars      print ("enter letter")     # there number in list     # if yes following else print list      # ask letter user     letter = input("enter letter: ")      # confirm whether letter correct or not     if letter in l:     # find position of letter in list         position = (l.index(letter));     # make variable called number value @ same position in n list         number = n[position];     # replace numbers in list letter entered         n_strings = [item.replace(number, letter) item in n_strings];     # print list numbers replaced         print (n_strings, "\n");         print ("please guess again. \n");         letter = input("enter letter now: ")     # repeat until list contains letters     else:         print ("that not correct");         print ("please guess again. \n");         letter = input("enter letter now: ")

you change logic , shorten code.

while true:     if all(x.isalpha() x in n_strings ):         print("all guessed correct {}".format(n_strings)) # if alpha print final n_string , break out of loop         break     print n_strings         letter = input("please enter letter: ")     if letter in l:     # find position of letter in list         position = (l.index(letter));         number = n[position];         n_strings = [item.replace(number, letter) item in n_strings];         print (n_strings, "\n");     # repeat until list contains letters     else:         print ("that not correct");         print ("please guess again. \n");
