now, let's proceed with the tutorial.
step 1: import the required libraries
start by importing the necessary libraries, including pandas. open your preferred python environment (such as jupyter notebook or a text editor) and create a new python script or jupyter notebook.

step 5: save the dataframe to a local csv file (optional)
if you want to save the downloaded data to a local csv file, you can use the to_csv method. for example:
