Shouldn´t I just add a element to the list. I have done it by append. Even renamed the list.

Log
0 #input len
1 #output len
Test Passed
Random Tests
Log
2 #input len
3 #output len
3 should equal 4

Quote: "Could you please check the length of input and output (after receiving the output)? The output should have one extra value than input."

How to insert 1 value in the test and then 2 in the random tests? I just can pass one of both tests.

Test Passed
Log
[]
[12]

Random Tests
Log
[36, 76] #input
[36, 76, 12] #out
3 should equal 4

Can somebody help me to understand what I had to do?
First I thought I should just return 'True', but it doesn´t matter what I return. The first test will always pass and some tests always fail.

The description is kind of strange and logically wrong.
isLeapYear(2000), True, 'Year 2000 was a leap year!' but 2000 is divisible by 100. So it should be no leap year.Also 1100 is divisible by 4, so is should be a leap year.
You should add the order of the rules or something to specify when to use which rule.

The description is wrong: (Python)
no strings will be passed into the list.

Test failed due to:
['o', 'l'] should equal False

Try to change the example to one of the test cases. First I thought I always had to take 5 L. Just change to "water" var.

Ok I couldn´t finde some helpfull link. Perhaps I could finish this Kata later.

But here it makes no difference. Are there cases with an different solution? I only know or and | is a different with bigger numbers.

Is there a rule when to use "and" and when "&" ?

Perhaps because the tasks aren´t that hard (python). Just copy the code and run it line by line with printing each new part. Best practice would be with a comment.
