[issue25673] unittest assertLessEqual not working properly with lists

[kehlert]

New submission from kehlert:

I attached a file that explains the issue. Basically, assertLessEqual only 
seems to compare the first elements of the two lists and ignores the others. 
Thus a test can pass when it shouldn't.

[issue25673] unittest assertLessEqual not working properly with lists

[Ezio Melotti]

Ezio Melotti added the comment:

This is how comparison works for sequences and it's not a bug:

>>> a = [1, 2]
>>> b = [2, 1]
>>> a <= b
True
>>> a = [2, 1]
>>> b = [1, 2]
>>> a <= b
False
