Find the number of characters in the Python list factor

names=["Mr. Kim", "Jadoo", "IU", "Darius", "Hani"]
print(len(names[0]))

I ran it and found 12
What I want is to print out the number of characters in the 0 of the list names I don't know what's wrong
Obviously, print(names[0]) makes "Kim" appear well;

Surprisingly, The Python version is 2 or 3, and whether it was compiled to support UCS-4 when compiling Python.The reason why this might not be surprising is that byte lengths can be different for all seemingly one Unicode character.

What is common sense in the programming industry is: One letter letter is 3 bytes. Therefore, "Kim" is 12 bytes.

Test the following by running it in multiple environments:

print(len("a") # 1 byte
print(len("̈") # 2 bytes
print(len("A") # 3 bytes
print(len("household") # 3 bytes
print(len("😂") # 4 bytes
print(len("🤷🏻♂️") # 17 bytes (U+1F937 + U+200D + U+2642 + + U+FE0F)

names=["Kim"], "Kim Plum", "IU", "Darius", "Hani"]
print(len(names[0]))

I think the reason why there is 12 in is because Python treats one word in Korean as 3 bits. But I think it's version 3 from the past

If you want to do it with the number of characters,

print(len(names[0])/3)

I think you can do it with that
