Error when generating dictionary from 2 lists












-1















I have some code that takes a string input,
translates it to a list of integers using a dictionary
then generates a dict from that list and a list of the alphabet
(I would like to use the alphabet list as the key)



alphabet = ['a','b','c','d','e','f','g','h','i','j','k','l','m','p','q','r',
's','t','u','v','w','x','y','z',' ','.','-','-',',','!','?']

def gen_dict() :
key_dict = {'a':'00', 'b':'01', 'c':'02', 'd':'03', 'e':'04', 'f':'05',
'g':'06', 'h':'07', 'i':'08', 'j':'09', 'k':'10', 'l':'11',
'm':'12', 'n':'13', 'o':'14', 'p':'15', 'q':'16', 'r':'17',
's':'18', 't':'19', 'u':'20', 'v':'21', 'w':'22', 'x':'23',
'y':'24', 'z':'25', ' ':'26', '.':'27', '-':'28', ',':'29',
'!':'30', '?':'31'}
print(key_dict)
p= 0
key = key.lower()
for character in key:
keyint.append(key_dict[message[p]])
p += 1
letter-num_dict = {k:v for k,v in zip(alphabet,keyint)}
print(letter-num_dict)
key = input()
gen_dict()


but the program won't even run,
instead it gives the error message:




letter-num_dict = {k:v for k,v in zip(alphabet,keyint)}
^ SyntaxError: can't assign to operator




I couldn't find anything else online getting this error message for similar reasons so any help is appreciated.

  • Python cannot use variable names with an operator in them: letter-num_dict is as invalid as, say, 10 or a+b, for a variable name.

    Variables cannot have a dash (-) as a part of the name, as Python interprets that as the minus operator. Change it to an underscore instead: letter_num_dict
