All of this has been done before - see the "Linked list" series by @JDeBolt. ( One of the folds may be missing. )

Consistency would be nice. Your function names are all over the place and your argument order is not consistent ( or standard ) either.

Why is listMapTwoParams limited to lists of the same length?

Why can't lists be infinite? You're missing the best feature of linked lists because you're letting yourself be restricted by a strict language. ( Actually, best feature and the only feature that makes it worthwhile doing this anyway. If we have already arrays, why would we have linked lists with worse performance? )

If you have doubts on what exactly should a function return, look at the provided example test cases. If you still have doubts, feel free to ask!

The description should clearly explain the task with all the requirements.

The output should be a tuple.

If days part of the output should be in range [1; 31), then the timestamp must have days > 1 too.

4865-39-02-13-82-28
y = 4865, m = 39, d = 2, h = 14
y = 4868, m =  3, d = 2, h = 14

[4868, 3, 2, 14] should equal [4868, 3, 1, 14]


43845770626718

[4388, 11, 11, 15] should equal [4388, 11, 10, 15]


61979031284159

[6204, 7, 1, 4] should equal [6204, 6, 31, 4] - 31 days in June?!

Your solution is incorrect.

if isLeapYear(y) and m >= 2 and d != 0:
    if d > 1:
        d -= 1
    else:
        m = range(12)[m-1]; d = DPM_LY[m]

What the hell is this? For 0000-99-00-00-00-00 it returns [8, 3, 1, 0], for 0000-99-01-00-00-00 it returns [8, 2, 31, 0], and for 0000-99-02-00-00-0 it returns [8, 3, 1, 0] again!

Days per month should represent the real life situation

Either your solution or the description is completely wrong:

• Days are supposed to be converted into months assuming that the calculation is performed since the start of the year - in a string 0000_99_01_00_00_00 the 01 is the first of January, not the first of April
• Leap years are ignored
• Seconds are ignored

The information about HH is missing from the input specs.

Hi,

No random tests.

Function parameter str is the same as a built-in.
