Count the number of filtered characters and character frequencies of a string | Python

Counting the number of filtered characters means we count the characters of a string after removing its duplicates. Besides, we also return the character frequencies of a string using dictionaries and loops in python.

First, we will iterate through the string and proceed with our process by adding the key and values with some if-else statement rules.

If we want to get the result irrespective of upper or lower cases then we can change the whole string into the upper case or lower case.
If we want the result as uppercase characters and their frequency then change the whole string to uppercase else change it to lowercase.
So for this, I create a variable and iterate through that.
string2 = string.upper()
for i in string2:

output for the above case : {G:2, O:2, L:1, E:1}
You can do string.lower() for the output {g:2, o:2, l:1, e:1}
