prefixes = json.load(f)
return prefixes['prefix']
client = commands.Bot(command_prefix=get_prefix, case_insensitive=True)
通过使用
try
,except
我们可以在出现任何错误时运行代码块
当公会已经拥有设置.json
时,它会返回前缀!否则它将为该公会创建一个新的settings.json!。
注意:将一些值设置为数据dict!将一些值存储到创建的settings.json中
def get_prefix(client, message):
try:
with open(f'Data/{message.guild.id}/settings.json', 'r') as f:
prefixes = json.load(f)
return prefixes['prefix']
except:
data = {'prefix':'!'}#data is dict to save something on it
with open(f'Data/{message.guild.id}/settings.json', 'w') as f:
json.dump(data, f)
return data['prefix']
client = commands.Bot(command_prefix=get_prefix, case_insensitive=True)
