Program debugging method and device

The invention discloses a program debugging method and device, and belongs to the technical field of program development. The method comprises the steps that an execution graph of a program is displayed to a user through a graphical user interface (GUI), the execution graph comprises one or more execution nodes, and each execution node represents execution steps of the program; receiving a display node adding instruction sent by a user; based on the display node adding instruction, adding a display node at the output end of a target execution node in the one or more execution nodes; starting program debugging according to an instruction of a user; and providing output data of the target execution node in the debugging process for a user by utilizing the display node. According to the method, the function that a program development platform carries out visual debugging on the program based on the execution graph of the program is enriched. 本申请公开了一种程序调试方法及其装置，属于程序开发技术领域。该方法包括：通过图形用户界面GUI向用户展示程序的执行图，执行图包括一个或多个执行
