Splits values into two groups according to a function, which specifies which group an element in the input list belongs to.
If the function returns True, the element belongs to the first group; otherwise, it belongs to the second group.
Use list comprehension to add elements to groups, based on fn.
def bifurcate_by(lst, fn):
return [
[x for x in lst if fn(x)],
[x for x in lst if not fn(x)]
]
bifurcate_by(
['beep', 'boop', 'foo', 'bar'],
lambda x: x[0] == 'b'
) # [ ['beep', 'boop', 'bar'], ['foo'] ]
