Function: startswith

The startswith() function checks if a string begins with a specified substring. It returns true if the string starts with the given substring, and false otherwise. This comparison is case-sensitive.

For case-insensitive matching, you can combine startswith() with the lower() or upper() functions.

Syntax:

<string>.startswith(<string>)

Example:

var.log_message = "Error: Connection refused."

case var.log_message.lower().startswith("error"):
    return DEBUG, "Log message indicates an error."
