I really can't figure how to add a string or any data type to a dictionary?

Question

Given a string as input, you need to output how many times each letter appears in the string.
You decide to store the data in a dictionary, with the letters as the keys, and the corresponding counts as the values.
Create a program to take a string as input and output a dictionary, which represents the letter

count.

Sample Input
hello

Sample Output
{'h': 1, 'e': 1, 'l': 2, 'o': 1}

Answer 1

Musharraf ,

here are some basic tasks about dictionaries that are required to solve the exercise:

letters = {} # create an empty dict
print(letters)
letters['a'] = 1 # add a new key 'a' to the dict with the value of 1
print(letters)
letters['a'] = letters['a'] +1 # modify the value of an existing key 'a' by increasing it by 1
print(letters)
if 'a' in letters: # check if a key already exist
print("found")
# do something
else:
print("not found")
# do something else

Answer 2

If this is for the project module.
You just loop over the letters in the text. (for-in)
Check if the letter is in the dictionary. If it is then add 1 to its value. If not then add it to the dictionary with a value of 1. Output the dict after the loop.
I suggest you review the for loop section and dictionaries. If you have any further issues, post a link to your code attempt and explain what your issue(s) are.

Answer 3

You can use OrderedDict for the purpose
