How to separate list elements with comma in pandas

I have this dataframe:

d = {'col1': [1, 2,3,4,5], 'col2': [6,7,8,9,10]}
df = pd.DataFrame(data=d)
print(df)

which looks like this:

   col1  col2
0     1     6
1     2     7
2     3     8
3     4     9
4     5    10

I then transform the col1 into a list:

a = df['col1'].values
print(a)

which looks like this:

[1 2 3 4 5]

I’d like to get the elements in list a to look like this:

[1,2,3,4,5]

How can I do that in pandas?

>Solution :

Just make it a list 🙂

list(df['col1'])
