First, we have to install the pyPdf module, as follows:

pip install pyPdf

Now, we will write a metadata_example.py script and we will see how we get the metadata information from it. We are going to write this script in Python 2:

import pyPdf
def main():
            file_name = '/home/student/sample_pdf.pdf'
