Remove the last N elements of a list

Question

Is there a a better way to remove the last N elements of a list.

for i in range(0,n):
    lst.pop( )

Answer 1

This is one of the cases in which being pythonic doesn't work for me and can give hidden bugs or mess. None of the solutions above works for the case n=0. Using l[:len(l)-n] works in the general case:

l=range(4)
for n in [2,1,0]: #test values for numbers of points to cut
    print n,l[:len(l)-n]

This is useful for example inside a function to trim edges of a vector, where you want to leave the possibility not to cut anything.
