python return list without specific element code example

Example: python return list without element

I assume you mean that you want to create a new list without a given element, 
instead of changing the original list. One way is to use a list comprehension:

m = ['a', 'b', 'c']
n = [x for x in m if x != 'a']
n is now a copy of m, but without the 'a' element.

Another way would of course be to copy the list first

m = ['a', 'b', 'c']
n = m[:]
n.remove('a')
If removing a value by index, it is even simpler

n = m[:index] + m[index+1:]
