Hello Group,
I'm Rajiv working as web developer in bangalore.
Objective:
We need to convert the list containing integers and nested list of integer
in it
e.g.) x = [[1, 2, [3]], 4]
into a flat list format
e.g.) result = [1, 2, 3, 4]
MyAnswer using Recursive function:
def flat_it(List):
result = []
for item in List:
if type(item) is int:
result.append(item)
else:
result += flat_it(item)
return result
print flat_it(x)
This actually works, but I tried to optimize this with List comprehension
like the following code, but it never worked
def flat_it(List):
return [item if type(item) is int else flat_it(item) for item in List]
print flat_it(x)
This returns result without flatting like what i passed in argument [[1, 2,
[3]], 4]
please help.
