Please help me fix this logical error

Question

I have written a code that concerts any emoji to heart.
It works fine. But I have come across some logical error I don't know how to fix.

In my code if you input more than one emoji it will behave weirdly.

I tried to fix it myself by adding some condition like:
If len(emoji) > 1:
print("I only convert EMOJIS to heart")

But this doesn't work on all emojis because

len("☺") #1

BUT

len("👩‍⚖️") #4

Although I have input only one emoji both the times..

I hope you understand my question and help me solve it.

Here's my code

Answer 1

Yeah, you are right. As I said before, Emojis are complex. They usually consist of smaller emojis. For instance, 👨‍👩‍👧‍👦 is actually, ['👨', '\u200d', '👩', '\u200d', '👧', '\u200d', '👦']. So, there’s no way to figure that out using pure python. The only solution that comes to my mind is having a dictionary of all available emojis and their corresponding smaller elements and compare them when you’re reading the input. Hope that helped.

Answer 2

emojis are not simple characters. A lot of them are actually compound, some more than 2, as you have discovered.

you can also do this for some characters. example, see how the e was modified

s = "cafe" + "\u0301"
print(s)

Answer 3

On line 27, change the condition to this:

if check and not check.isdigit() and not check.isalpha() and check not in list and not check.isspace() and len([e for e in check])==1:

“len([e for e in check])==1” will guarantee that it’s just one emoji no matter what the length of the emoji is.

Answer 4

Alex,

On your first suggestion:

It still doesn't work properly...

If I input
'👨‍👩‍👧‍👧'

It takes:
👨

Which is not what I expected...

On second suggestion:
If I input:
'👨‍👩‍👧‍👧'

It doesn't work at all😅
