<｜begin▁of▁sentence｜>### Instruction:
As a User Experience (UX) designer working on a data analysis application, you need to integrate the ClassicPythonShell from igraph's app.shell module into the application's interface. This interactive Python command execution feature will allow users to perform advanced data analysis and manipulation directly within the application, enhancing usability and user satisfaction.
### Response:
from igraph.app.shell import ClassicPythonShell

# Initialize the Classic Python Shell
classic_shell = ClassicPythonShell()

# Use the shell in your application
# This is a placeholder for where you would use the shell, as it's an interactive component,
# the exact usage would depend on the application context.
classic_shell.mainloop()
