How in Pandas Dataframe and Python can extract the specific text string after a given word?

I would like to extract the text inside the range "text: ….." from this dataframe and create another column with that value.

This is my Pandas Dataframe

issues_df['new_column'] = issues_df['fields.description.content'].apply(lambda x: x['text'])

However, it returns the following error:

issues_df['new_column'] = issues_df['fields.description.content'].apply(lambda x: x['text'])
TypeError: Object 'float' is not writable.

Any suggestions?

Thanks in advance.

>Solution :

Problem is NaN in column, you can try .str accessor

issues_df['new_column'] = issues_df['fields.description.content'].str[0].str['content'].str[0].str['text']
