How to insert a list into a cell with Python Pandas?

Sometimes, we want to insert a list into a cell with Python Pandas.

In this article, we’ll look at how to insert a list into a cell with Python Pandas.

To insert a list into a cell with Python Pandas, we can assign the list we want to insert to the location in the data frame we want to insert it in.

For instance, we write:

import pandas as pd

df = pd.DataFrame(data={'A': [1, 2, 3], 'B': ['x', 'y', 'z']})

df.at[1, 'B'] = ['c', 'd']

We create a data frame by using the DataFrame class with a dictionary.

Then we assign the list ['c', 'd'] into the location [1, 'B'] with:

df.at[1, 'B'] = ['c', 'd']

Therefore, df is now:

   A       B
0  1       x
1  2  [c, d]
2  3       z
