Hi all,
Had a simple problem that turned into an interesting solution and I
thought I would share it here.
I had a list of tuples that I needed to get the first value from and
generate a list.
tuple_list = (
('John', 'Doe'),
('Mark', 'Mason'),
('Jeff', 'Stevens'),
('Bat', 'Man')
)
# what I'd do in C or other procedural languages
result_list = []
for item in tuple_list:
result_list.append(item[0])
# the first Pythonic attempt using comprehensions
result_list = [x[0] for x in tuple_list]
# the final functional way
[result_list, _] = zip(*tuple_list)
I really like how Python allows me to do what I feel is the most
natural solution (for a seasoned procedural programmer) while allowing
a satisfying path towards a more functional approach.
Cheers,
James
