How do I count the character in a string

Question

I want to count how many characters are there in a string but not occurences. For example:

test_list=("aabbccddee")

I want the result to be 5 because there are 5 characters:

(a,b,c,d,e)

I tried using len function and count and also

from collections import defaultdict

Does this solve your problem?

from collections import Counter

given_string = "aabbccddee"
result = Counter(given_string)
print(len(result))

Use set in python.

len(set("aabbccddee"))
# returns 5

‍sets in Python do not contain repeated members (nor are they ordered) like sets in math. Another syntax to define a set is like a dictionary without keys:

set_example = { 1, 2, 2, 3, 3, 3 }
# set_example is { 1, 2, 3 }

Try this one:

your_str = 'aabbccddee'

result = len(set(your_str))
print(result)

An alternative to set():

len(dict.fromkeys(test_list))
#5
