在python中的字典列表中搜索前缀

Question

我目前有一个字典列表

list_of_dicts = [{"name": 'stfdahbancssc',"status":'running'},
                 {"name": 'stfdahbancssc',"status":'running'}]

我想检查如何匹配前缀 'stf' 并打印 stf 存在，否则 stf 不存在。

Answer 1

迭代字典，获取“名称”值，检查前缀，打印消息：

list_of_dicts = [{"name": 'stfdahbancssc',"status":'running'},
                {"name": 'stfdahbancssc',"status":'running'},
                {"name": 'none'}]

for idx,d in enumerate(list_of_dicts): 
    if d.get("name","").startswith("stf"):
        v = d["name"]
        s = d["status"]
        print(f"The {idx} dictionary has {v} as {s}")
        print("a")
    else:
        print(f"The {idx}. dictionary has no name starting with 'stf'.")    

输出：
