I might be wrong but should this test below

Test.assertEquals(findSuperMan("Hello, I am SxuxpxexrxMxaxn"), "Hi, SuperMan!", "s u p e r m a n is a SuperMan")

be written

Test.assertEquals(findSuperMan("Hello, I am SxuxpxexrxMxaxn"), "Are you crazy?", "s u p e r m a n is a SuperMan")

SxuxpxexrxMxaxn removing "x"s youre lesft with SuperMan and super man is secretive right?

The test case for python are not working...you have mixed up the function name find_super_man and findSuperMan....try testing any python codebase

yeah, in the first four best practices that currently passed, s='ssuuppeerrmmaann' is considered superman. so I'm puzzled. I chose the issue incorrectly, but I don't know how to turn the issue into a question.

Because in the first case that am is not part of the Superman hidden word and in the other, an is part of the hidden superman word.

The answer is no, it's not a superman, you have several pairs of superman letters there. And why is this an issue and not a question? I see that some solutions that currently passed, would fail a test like that.

"2. Because Superman usually careful to hide the word 'Superman' in a sentence, and each of the two letters are not continuous."
so, "ssuuppeerrmmaann" is superman ?

In basic test, s="Hello, I am SxuxpxexrxMxaxn" is superman, ingore "am"; but in random test, s="c gobinax fzdbyhmorolqyehpokwlduii s" is not superman, not ingore "na". I want to know why?
