test

This subroutine attempts to ping google’s servers. If this is successfully it means there is currently an internet connection to your PC. This is not run in a thread, so therefore there is a 1 second timeout. This means that if there isn’t an internet connection available it doesn’t slow down Pycraft’s startup too much.

• Args:

  • None

• Keyword Args:

  • None

• Output:

  • (bool): This subroutine will return True if an internet connection can be established. If an internet connection could not be established, nothing is returned.
