In this kata, your task is to create a function that takes a single list as an argument and returns a flattened list. The input list will have a maximum of one level of nesting (list(s) inside of a list).
```python
# no nesting
[1, 2, 3]
# one level of nesting
[1, [2, 3]]
```
---
# Examples
```python
>>> flatten_me(['!', '?'])
['!', '?']
>>> flatten_me([1, [2, 3], 4])
[1, 2, 3, 4]
>>> flatten_me([['a', 'b'], 'c', ['d']])
['a', 'b', 'c', 'd']
>>> flatten_me([[True, False], ['!'], ['?'], [71, '@']]) 
[True, False, '!', '?', 71, '@']
```
Good luck!
def flatten_me(lst):
    res = []
    for i in lst:
        if type(i) is list:
            res += i
        else:
            res.append(i)
    return res

def flatten_me(lst):
    res = []
    for i in lst:
        if type(i) is list:
            res += i
        else:
            res.append(i)
    return res
