如何将多个分组字段传递给一个参数

function processGroups(groups) {
  for (let i = 0; i < groups.length; i++) {
    // 处理每个分组字段
    console.log(groups[i]);
  }
}

const groups = ['group1', 'group2', 'group3'];
processGroups(groups);

def process_groups(groups):
    for key, value in groups.items():
        # 处理每个分组字段
        print(key, value)

groups = {'group1': 'value1', 'group2': 'value2', 'group3': 'value3'}
process_groups(groups)

public static void processGroups(String groups) {
    String[] groupArray = groups.split(",");
    for (String group : groupArray) {
        // 处理每个分组字段
        System.out.println(group);
    }
}

String groups = "group1,group2,group3";
processGroups(groups);
