I have a Dataframe that look like this (small version):

```
    A   B   C
0   125 ADB [AF:12]
1   189 ACB [AF:78, AF:85, AF:98]
2   148 ADB []
3   789 ARF [AF:89, AF:85, AF:12]
4   789 BCD [AF:76, AF:25]

```

How can I see if some of the items in column "C" are in a list?
knowing that when I do type(df.C) I get `class 'pandas.core.series.Series'`

if for example the list is:

```
['AF:12', 'AF25']

```

The expected output would be:

```
    A   B   C                        D
0   125 ADB [AF:12]                  True
1   189 ACB [AF:78, AF:85, AF:98]    False
2   148 ADB []                       False
3   789 ARF [AF:89, AF:85, AF:12]    True
4   789 BCD [AF:76, AF:25]           True

```

I have tried `df['D'] = df['C'].isin(list)`
but get False everywhere probably because "C" is a list of list.

Is there a way to get around that?

Any help would be greatly appreciated
