Variable assignment method, medium, device and computing equipment

The embodiment of the invention provides a variable assignment method, a medium, a device and computing equipment, the method is applied to a visual programming platform for displaying a programming interface, and the programming interface at least comprises a first area for displaying selectable variables and a second area for displaying selectable expressions. The method comprises the following steps: determining a to-be-assigned target variable in selectable variables by responding to a first operation instruction for a programming interface; the target variable is a multi-field variable; in response to a second operation instruction for the programming interface, determining a target expression corresponding to the target variable; according to the method, the target variable is assigned on the basis of the target expression, the multiple selectable multi-field variables and the multiple selectable expressions are displayed on the programming interface, multiple fields in the multi-field variables can be
