Word Count Python Challenge. 

def word_count(string):
  new_list=string.split()
  unique=set(new_list)
  my_dict={}
  for unique in new_list:
    my_dict[unique]=new_list.count(unique)
  return my_dict

Give me your opinions on how you did it

Less code:

from collections import Counter

def word_count(word): l_word = word.lower().split() print Counter(l_word)

string = "erion jade erion jade jade jade erion eleksa eleksa eriona"
string_list = string.lower().split()
string_dict = {}

def word_count(word):
    for word in string_list:
        if word in string_dict:
            string_dict[word] = string_dict[word] + 1
            continue
        else:
            string_dict[word] = 1

    return string_dict

dict = word_count(string)
print(dict)

I did it without the use of Counter which Kenneth suggested. I looped through all words (after split to list) and added the word to the dict as a key if they did not already exist with a value of 1. If the key already existed, then I simply added 1 to the value already assigned to the key.

I did it like this:

def word_count(string):
    word_count = {}
    string = string.lower().split(" ")

    for word in string:
        if word in word_count:
            word_count[word] += 1
        else:
            word_count[word] = 1

    return word_count

print(word_count("I aint no tadpole I is what I is"))

  for word in sentence:
    if word not in blank:
      blank[word] = 1
    else:
      blank[word] += 1
  return blank

here's mine.

Look up Counter and you'll have even less code :)

def word_count(string):
    split_string = string.lower().split()
    my_dict = {}
    for word in split_string:
        word_occurence = 0
        while word in split_string:
            word_occurence += 1
            my_dict.update({word:word_occurence})
            split_string.remove(word)
    return my_dict

I didn't know about the Counter or count() so I ended up with this medieval solution

This should pass the challenge:

word_dict = {}
def word_count(string):
    string_list = (string.lower()).split()
    for item in string_list:
        if item in word_dict:
            word_dict[item] +=1
        else:   
            word_dict[item] = 1
    print(word_dict)        

word_count("I am that I am I that am  guy guy")

I try to do without a split or Counter. My code end like this (some kind of lines of code could be remove, but i want a new challenge =P)

def word_count(string): new_string = string.lower() list_of_string = [] new_string_to_see = [] for word in new_string: if not word.isspace(): new_string_to_see.append(word)

    else:
        end_string="".join(new_string_to_see)
        list_of_string.append(end_string)
        new_string_to_see = []

if not new_string[-1].isspace():
    end_string="".join(new_string_to_see)
    list_of_string.append(end_string)

count = 0
list_of_string.sort()

words = []
counts = []
i=len(list_of_string)-1   
while i>=0:
    count = 1
    words.append(list_of_string[i])
    j = i-1
    while list_of_string[i]==list_of_string[j]:
        count +=1
        j-=1
    counts.append(count)
    i=j 

dictionary = {}
i=0
for string in words:

    dictionary[string] = counts[i]
    i+=1
return dictionary

string_teste = "This code is so so so long for good sake." resultado = word_count(string_teste) print(resultado)
