How to Extract a Specific Value from a Dataframe Cell After Filtering?

Extracting a Single Value from a Dataframe Cell

In this scenario, you aim to extract a specific value from a cell within a dataframe. While you have successfully isolated the row containing the target cell using conditional filtering, you encounter an issue when attempting to retrieve the value directly from the dataframe.

To obtain the desired float number, follow these steps:

1. Utilize iloc to access the first (and only) row of the dataframe as a Series:

<code class="python">sub_df = df[(df['l_ext']==l_ext) & (df['item']==item) & (df['wn']==wn) & (df['wd']==1)]
val = sub_df.iloc[0]</code>

2. Access the desired value using the column name:

<code class="python">specific_value = val['col_name']</code>

By following these steps, you can successfully extract the specific value from the targeted cell.
