good tip, will try

I love it, but seem to fail the random tests. How could this be?
Time: 553ms Passed: 77 Failed: 27 Exit Code: 1

Hey, thank you for your reply,

I will keep on trying, best I got so far is

invalid literal for int() with base 10: 'a'

Time: 2553ms Passed: 57 Failed: 44 Exit Code: 1

# list of columns gotten with to_list()
tst_5 = [[3, 3, [0, 5, 6, 9, 10, 10, 6]]]

# my call to flatten to simulate the failed test
print(flatten(pd.DataFrame(data=tst_5[0], columns=list("A"))))

# returnable inside the function
{'A': [3, 3, 0, 5, 6, 9, 10, 10, 6]}
# tested with DataFrame() and DataFrame().to_dict() same fails

fails and outputs:

Wrong output: Expected:
    A
0   3
1   3
2   0
3   5
4   6
5   9
6  10
7  10
8   6

Actual:
    A
0   3
1   3
2   0
3   5
4   6
5   9
6  10
7  10
8   6

It fails even with a single column. Any help please?
Here is the dtypes output

A    int64
dtype: object

Nice one, can't wait for the python translation.
