DAPP流动性质押LP系统开发技术方案
佛萨奇源码,188合约1928系统8024,智能合约技术是通过数字货币实现还是通过账户实现,还值得探索。这方面不能单纯从技术角度看问题,更要从货币流通、货币发行的特点看问题。我的看法是,不排斥通过数字货币执行合约的方式,但应该限制在一些特定领域
if args['userId']in list(data['userId']):
#eva luate strings of lists to lists
data['locations']=data['locations'].apply(
lambda x:ast.literal_eva l(x)
)
#select our user
user_data=data[data['userId']==args['userId']]
#update user's locations
user_data['locations']=user_data['locations'].values[0]
.append(args['location'])
#save back to CSV
data.to_csv('users.csv',index=False)
#return data and 200 OK
return{'data':data.to_dict()},200
else:
#otherwise the userId does not exist
return{
'message':f"'{args['userId']}'user not found."
},40
这时候更奇怪的事情发生了,报错的位置甚至提前了,次至少from.b import f2没有报错,现在居然也报错了?
Traceback(most recent call last):
File"g:learner_lucode-grammarpythonfolder1a.py",line 3,in<module>
from.b import f2
ImportError:attempted relative import with no known parent package
报错原因是“尝试在没有已知父包的情况下进行相对导入”,明明我用from b import f2来导入没有问题呀,a.py和b.py同目录我导入加一个同目录的.又有什么问题呢?这些报错又都是什么意思呢?
