将值作为列表添加到字典键

add value to dictionary key as list

是否可以将字典的键值视为列表?

如何向该列表附加新值?

#my dictionary
mydic = {}

#my key
username = "praveen"

#my value
user_accessKey = "tmp1"
user_accessKey2 = "tmp2"

如何使用我的键和值构建这样的字典?

print (mydic)
{"praveen":["tmp1","tmp2"]}

简单的字典赋值

mydic[username] = [user_accessKey, user_accessKey2]

附加值(感谢@wjandrea 的建议):

mydic.setdefault(username, []).append(new_value)

最简单的就是直接做:

mydic = {username: [user_accessKey, user_accessKy2]}
