How to count number of letter occurences in multiple strigns simultaneusly using Counter in Python? Is + correct to use?

Question

I am trying to count how many times particular letters occur in given strings. Am I using Counter correctly? The question is can I calculate it from two strings at once using +? It looks like working, but Im not sure if its correct. Example - to find how many times letters t r u e occur in strings

    name1 = input("What is your name? \n")
    name2 = input("What is their name? \n")
    
    from collections import Counter
    
    lowercase_name1 = str.lower(name1)
    lowercase_name2 = str.lower(name2)
    
    cntr_true = Counter(lowercase_name1 + lowercase_name2)
    total_letters_true = cntr_true["t"] + cntr_true["r"] + 
    cntr_true["u"] + cntr_true["e"]

    number = total_letters_true
    print(f"{number}")

Result:

What is your name? 
True 
What is their name? 
Tr ue
8

Answer 1

from collections import Counter
name1 = input("What is your name? \n")
name2 = input("What is their name? \n")
list1=list(str.lower(name1+name2))
res=Counter(list1)
print("Letter Count: ")
for key in res:
    print(key, ':', res[key])

This code will count occurance of each letter in name1 and name2

Below Code will print t r u e occurrence only and exclude rest of letters

from collections import Counter
name1 = input("What is your name? \n")
name2 = input("What is their name? \n")
list1=list(str.lower(name1+name2).strip())
res=Counter(list1)
print("Letter Count: ")
t=0
for key in res:
    if key=='t' or key=='r' or key=='u'or key=='e':
        t=t+res[key]
        print(key,':',res[key])
print("Total Counter Value: ",t) 

Output:
