The Python PyQt5.QtWidgets.QSpinBox.blockSignals() function is used to temporarily block the emission of signals from a QSpinBox widget. By calling this function, any signal emitted by the QSpinBox will be ignored until the signals are unblocked. This is particularly useful when it is necessary to prevent signals from being processed temporarily, such as during a batch update, without disconnecting the signal and risking the loss of important data.
