I have the following list of lists (denoted by lol
):
[['365', '336', '365', 'E<;EjD'], ['365', '336', '365', 'E<;EkD'], ['365', '336', '365', 'E<;F0D'], ['0', '0', '335', 'E<;GaQ'], ['0', '0', '335', 'E<;GbQ']]
I am trying to convert lol
in such a way that each first three strings of a sub-list to be converted to int
and each last string of the same sub-list to be converted to datetime
(dateConverter()
is to convert string to daytime).
I am expecting to have as output the following:
[[365, 336, 365, '2021-12-11T21:58:20'], [365, 336, 365, '2021-12-11T21:58:20'], [365, 336, 365, '2021-12-11T21:59:20'], [0, 0, 335, '2021-12-11T22:0:20'], [0, 0, 335, '2021-12-11T22:1:20']]
I tried the following:
- I knew how to convert the first three strings to
int
.
[list(map(int, li[:-1])) for li in lol]
- I knew how to convert the last string to
daytime
.
list(map(dateConverter, [li[-1] for li in lol]))
- I did not know how to do that 2-in-1 using
map
function or any other way. I tried the following but did not work for me.
[list(map(int, dateConverter, li[:-1], li[-1])) for li in lol]

What about this?
lol = [['365', '336', '365', 'E<;EjD'], ['365', '336', '365', 'E<;EkD'], ['365', '336', '365', 'E<;F0D'], ['0', '0', '335', 'E<;GaQ'], ['0', '0', '335', 'E<;GbQ']] converted = [ [int(x) if i < 3 else date_converter(x) for (i, x) in enumerate(li)] for li in lol ]
