[Solved] Not Sure How To Make A Counter [closed]

  1. Count how many of each alphabetic character.

Use a dictionary:

It is best to think of a dictionary as an unordered set of key: value pairs, with the requirement that the keys are unique (within one dictionary). A pair of braces creates an empty dictionary: {}. Placing a comma-separated list of key:value pairs within the braces adds initial key:value pairs to the dictionary; this is also the way dictionaries are written on output.

e.g {"Key1" : "Value 1", 1 : 2, "Key3" : 4, 5 : "Value5"}

In this case, for counting, we could set up the dictionary to be like this:
{character : # of times it has shown up} e.g {"a" : 7, "b" : 29}

How would we use a dictionary as a counter? Well, you see, they have this cool feature. If the Value of a Key is an int() or float(), you can use it like an int or float! 

>>> example = {'letter' : 13}
>>> example['letter'] += 10
>>> example['letter'] 
23
>>> example['letter'] *= 1.02
>>> example['letter']
23.46

Knowing this, we could iterate through all the letters in a list or paragraph and either add them to the dictionary and set their value to 1 (if they have’t been added) OR, if they have been added, just += 1 to their value.
