我们可以通过两种方式使用 LangChain Core 对象: 命令式:即。直接调用它们,例如:model.invoke(...) 声明式,带有LangChain表达式语言(LCEL) 或者两者兼而有之!例如:LCEL 序列中的一个步骤可以是自定义函数。 合作包 当整合的长尾在langchain-community,我们将流行的集成拆分为它们自己的包(例如:langchain-openai,...
Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results. Local variable declarations are syntactic sugar because of the difficulty humans have with deeply nested method calls. A method chain is also ...
multiprocessing is for parallel execution within Python, while subprocess manages external processes. To execute multiple commands in sequence using subprocess, you can chain them by using pipes or running them consecutively.Read on to learn how to use Python’s subprocess module to automate shell tas...
上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。

You can use this function as an argument to the raise keyword, as you do in the above example.The from clause is also optional in the raise syntax. It allows you to chain exceptions together. If you provide the from clause, then another_expression must evaluate to another exception class ...
Speed up the generated __eq__ methods significantly by generating a chain of attribute comparisons instead of constructing and comparing tuples. This change arguably makes the behavior more correct, but changes it if an attribute compares equal by identity but not value, like float('nan'). #13...
18、The presence of the yield x keyword in function body means that this is not a normal function. It is a special kind of function which generates values one at a time. You can think of it as a resumable function. Calling it will return a generator that can be used to generate succe...
