a scanner for python3.6

Ok so this took a while, and I did find a really neat tool to strip punctuation from stackOverflow.

So far, I think I got everything covered.  It will take any dictionary, and any sentence and return a list of tuples of the words and numbers and things not found in either of those will be listed as 'error' in the returned tuple.

# a scan method:

from lexicon import game_lexicon

import re

# scan a dictionary and return tuples from it in a list

def scan(some_dict, some_sentence):

# empty tuple list

tuple_list = []

# try it, so if it fails, the scan function doesn't throw error

try:

#user_input = input(" give me a sentence...>")

# make the sentence Lower Case

sentance = some_sentence.lower()

# strip out the punctuations with re module and sub

cleansentance = re.sub(r'[?|$|.|!]',r'',sentance)

# split up the clean sentance

some_list = cleansentance.split()

print(some_list)

except:

print("input not testable.")

# take each word from the user_words list and do something:

for word in some_list:

# I can't use word as a key unless I say it's the key

key = word

#print(key) <--test print

# set success to False so words are only added when success is not True

success =False

try:

#first try and see if it is a number that the user entered

int(word) == word

#print(f"the integer {word} is accepted.") <--- test print

# add the number to the tuple_list if it is a number

tuple_list.append(('number', word))

# set success to True so number is not added to error tuples

success = True

# if it is not a number, check the dictionary

except ValueError:

# for the key or word in the dictionary put it in a tuple list with the value

for key in some_dict:

# define value

val = some_dict.get(key)

# if word is in the dictionary key, add to tuple_list with value

if word in val:

#print(f"word {word} FOUND!")

#print(f"{word} was found in {key} list")

tuple_list.append((key, word))

# set success to True so it is not added to error tuple

success = True

else:

# I'm not sure what to put in this else clause... so CARROTS!

carrots = 'carrots'

#print(f"word not found in {key}")

# i need a way to create tuples of errors that are not found in the lexicon

finally:

# if success is not true for the word that it's testing, add it as an error tuple in list

if not success:

tuple_list.append(('error', word))

else:

# I don't know what to put here, so CARROTS!

carrots = 'carrots'

#print("This word added to tuple list.")

# print it off, later version will be 'return' tuple-list

print(tuple_list)

sentance = input("Give me a test string:")

scan(game_lexicon, sentance)
