remove last element of list within a Series

I've tried different variations of pop, remove, and del with no success thus far. I'm not finding any documentation that addresses this particular issue. Thanks in advance

listoflists = [['a', 'b', 'c', 'd'],['e','f','g','h']]

series1 = pd.Series(listoflists)

->

0      [a, b, c, d]
1      [e, f, g, h]
dtype: object

I want to remove the last element of each list within the series to get:

0      [a, b, c]
1      [e, f, g]
del immutability series nested-lists pandas

You can use .apply() with lambda:

series1.apply(lambda x: x[:-1])

From each list we take all elements except of the last one.

Output:

0    [a, b, c]
1    [e, f, g]
