  Proposed question:
  
  How can I use Python to generate an RSA public/private key pair and save them to files in PEM format?
  
  Detailed Response:
  
  To generate an RSA public/private key pair and save them to files in PEM format using Python, you can utilize the `Crypto.PublicKey.RSA` module. Below is a Python script that accomplishes this task:
  
  
  from Crypto.PublicKey import RSA
  
  def generate_key_pair():
      key = RSA.generate(2048)
      pub_key = key.publickey().export_key().decode()
      with open('public.pem', 'w') as file:
          file.write(pub_key)
      
      priv_key = key.export_key().decode()
      with open('private.pem', 'w') as file:
          file.write(priv_key)
  
  generate_key_pair()
  
  
  This script generates a 2048-bit RSA key pair, exports the public key and saves it to a file named `public.pem`, and exports the private key and saves it to a file named `private.pem`.
output:     return key
