Variable operation method and device in graphical programming tool

Abstract

The invention discloses a variable operation method and device in a graphical programming tool, and the method comprises the steps: adding a variable logic graphical block corresponding to a variableto the graphical programming tool in advance, storing a code corresponding to the variable logic graphical block in a code storage unit, and enabling the variable logic graphical block to support a dragging operation; detecting a variable operation instruction, and analyzing the type of the variable operation; executing a corresponding operation on the variable logic graphical block according to an analysis result; and obtaining and executing a code corresponding to the operation according to the code storage unit, obtaining an output result of the code, and displaying the output result on a preview interface to finish the operation of the variable. According to the embodiment of the invention, the concept of variables is introduced to the field of graphical programming by children for thefirst time, the created programming work can temporarily store data by utilizing a variable tool, the realization of complex logic works can be supported, many unnecessary operations are reduced, thelearning cost of the variables is greatly reduced, and convenience is provided for children to learn programming.

Description

technical field [0001] The invention relates to the technical field of graphical programming, in particular to a variable operation method and device in a graphical programming tool. Background technique [0002] With the development and progress of society and the rapid development of computer science, programming has become an increasingly important basic ability for modern people, not just a full-time job for IT industry personnel. People of any age and any background have an increasing need to learn and experience programming. 4-7-year-old users have an increasing demand for learning programming, and children's graphical programming tools have emerged with the development of the times. The well-known graphic programming tools for children at home and abroad include: Little Rocket Children's Programming, Scratch JR, Tynker JR. Using these tools, users can independently complete programming with complex logic just by dragging and dropping programming components. [0003...
