How to find location of multiple elements in the DataFrame

There are several ways to find the location of multiple elements in a DataFrame. Below are three common approaches.

Using isin()

The code snippet creates a list of target students you want to find. It then uses the isin() method on the 0th column to select rows. Finally, it retrieves the index of those rows using the .index attribute.

Output:

         0   1      2    3
0    Ankit NaN  Delhi  NaN
1  Swapnil NaN  Delhi  NaN
2      NaN NaN    NaN  NaN
3      NaN NaN  Delhi  NaN
4      NaN NaN    NaN  NaN

In this article, we will see how to find the position of an element in the dataframe using a user-defined function. Let’s first Create a simple dataframe with a dictionary of lists.
