merging sublist into single list in python

[snippsat]

Just to use yield from

def flatten(seq):
    for item in seq:
        if isinstance(item, list):
            yield from flatten(item)
        else:
            yield item

>>> list1 = [ 'New', ['Group Name Details'], ['Group Name'], ['Person Phone Number'], ['Father Name']]
>>> [word for line in flatten(list1) for word in line.split()]
['New', 'Group', 'Name', 'Details', 'Group', 'Name', 'Person', 'Phone', 'Number', 'Father', 'Name']

>>> data = ['Andre Müller', ['hallo', '123'], [[[[['foo bar']]], 'bat']], 12]
>>> list(flatten(data))
['Andre Müller', 'hallo', '123', 'foo bar', 'bat', 12]
