To add dictionary items in a pandas column, you can first create a pandas DataFrame and then assign the dictionary as a value to a specific column. For example, you can create a DataFrame like this:
import pandas as pd
data = {'col1': [1, 2, 3, 4],
'col2': [{'key1': 'value1'}, {'key2': 'value2'}, {'key3': 'value3'}, {'key4': 'value4'}]}
df = pd.
