Strange out put on CamelCase vs camelCase Why ???
I ran several test on words and sentences and my code worked yet when I ran the two versions of CamelCase mentioned above I received two different results. CamelCase converted to all lowercase and no underscores... camelcase 🤔 camelCase converted to all lowercase as well but correct form as camel_case 👍 As I mentioned, I ran other test from AbraCadAbra ( abra_cadabra 🤔) to DicTionAry ( dic_tion_ary 👍) to AntiDisEstablishMenTarianIsm ( anti_dis_establish_men_tarian_ism 👍 ) I thought this was odd as this a SnakeCase code and yet when execution gave two different results .. https://code.sololearn.com/c0Z2xn1iJ8We/?ref=app

BroFar the conditions that cause failure are:
1. The first letter is capitalized
and
2. Another letter in the word matches that first letter.
It will skip inserting the underscore because of the logic in line 4 where it checks for a match with the first letter.

Thanks Jay Matthews but why does that print statement have to be outside the for loop ?
It did correct both the CamelCase entry and the AbraCadAbra entry ..
print(x[0].lower(),end="")
understandable that x[0] comparison is not needed in the flow of the for loop.

Thank you Jay Matthews But still don't exactly understand the other oddities like why the no underscore in CamelCase and the second missing underscore in AbraCadAbra as _abra ..
The if condition was an 'and' not an 'or' so elif condition is isupper() boolean by itself.

Ah yes that makes totally sense.. Thanks Brian I see the error of my ways.

You're welcome, BroFar. I find that it can be hard to find a bug when I am overconfident that my good intentions translated to a good implementation. It's a good example to explain to newbies why testing is necessary.

why the multiple print(end='')?
surely it would be more efficient to build a string then print at the end?
s = ''
for c in input():
if c.isupper():
s += f'_{c.lower()}'
else:
s += c
s = s.lstrip('_')
print(s)
or one liner:
print(''.join(['_'+c.lower() if c.isupper() else c for c in input()]).lstrip('_'))
and because it's Python, there's a library for this. 😁

But there is always the edge case of multiple consecutive uppercase that is always messed up...
example: IOError or HTTPRequest

It's PascalCase and cameCase
