Count character occurrences in a given sentence using python

In this post we learn how count characters, special characters #*&@.... and spaces occurrences in a given word, phrase or sentence.

sentence = input ("Enter sentence :")

def count_characters(sentence):
  length = len(sentence)
  count = {'count':1}
  for i in range(length):
  if sentence[i] in count.keys():
  count[sentence[i] ] += 1
  else:
  count[sentence[i] ] = 1
  del count["count"]
  return count

- length is a number of characters in sentence including spcial character @ $ #... and spaces.

- creat dictionary keys are characters and values are count of characters.

- count in beging has key 1 if I put count empty it is occure an error in if statement .

- for loop all string sentence from first character sentence[0] to last character sentence[lenght-1] as string in python is an array and order start from zero not one.

- if element sentence[i] in keys if element sentence[i] in not in keys creat new keys neme's sentence[i] and put value by one increase this value.

- delete from dictionary key count.

result = count_characters(sentence)

for key in result :print(key , " : " , result[key])
