List Comprehension to exclude first row
#6
(Jun-11-2018, 09:13 AM)perfringo Wrote: You are totally correct!

OP asked: "how could I use list comprehension to create a list that exclude the first row that contains header?"

There are also non-redundant ways of using list comprehension:

without_header = [v for i, v in enumerate(my_list) if i > 0]
or

without_header = [row for row in my_list if my_list.index(row) > 0]

A person asking question sometimes over-complicates possible solution due to lack of knowledge (not a sin). Those who know better may show a better way - instead of showing a wasteful code just to prove the point - and that is a sin Hand

Since slicing produces a list, it's somewhat obvious that slice may be used as a source for list comprehension.
Test everything in a Python shell (iPython, Azure Notebook, etc.)
