Thanks for contributing an answer to Stack Overflow! Does Python have a string 'contains' substring method? * @brief Adds a state to the state machine, * @param probe A function pointer to the state's init function, * @param enter A function pointer to the state's enter function, * @param run A function pointer to the state's run function, * @param exit A function pointer to the state's exit function, * @param name A string representation of the state's name, * @brief Sets the callback function for the state machine.
