vscode中的代码提示自定义

设置->用户代码片段->python.json

{
	// Place your snippets for python here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	"Print to console": {
		"prefix": "ros2_node_py",
		"body": [
			"import rclpy",
			"from rclpy.node import Node",
			"",
			"class Mynode(Node):",
			"    def __init__(self):",
			"        super().__init__(\"my_node\")",
			"",
			"def main():",
			"    rclpy.init()",
			"    rclpy.spin(Mynode())",
			"    rclpy.shutdown()",
			"",
			"",
			"if __name__ == \"__main__\":",
			"    main()"
