blocks|key|3195406|text|您可以使用Python+3参数和返回值注释指定有关函数参数的类型信息。如果您使用的是Python+2，还可以在函数的docstring中指定信息。PyCharm理解标准库中二进制模块的文档字符串所使用的格式，例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3195407|"""
foo(int,+string)+->+list

Returns+the+list+of+something

You can specify the type information about the parameters of the function using Python 3 parameter and return value annotations. If you're using Python 2, you can also specify information in the function's docstring. PyCharm understands the format used by docstrings of binary modules in the standard library, for example:

<pre><code>"""
foo(int, string) -&gt; list

Returns the list of something
"""
</code></pre>

blocks|key|276183|text|为了让PyCharm识别一个对象的实例并检索它的所有方法，我们必须使用以下语句。但我认为这两者都是浪费编程和运行时间的可怕方式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|276184|assert+isinstance(instanceX,+ClassOfInstanceX)++
instanceX.{#list+of+method/properties+appears}|code-block|syntax|javascript|276185|或者，您也可以使用类名来调用方法或属性，每次您想调用它并将实例传递给self参数时。但这对我来说太冗长了，尤其是对于嵌套类|276186|ClassOfInstanceX.{#list+of+method/properties+appears}
+++++#+then+you+will+have...
ClassOfInstance.method(instanceX,+args...)|276187|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

In order for PyCharm to recognize an instance of an object and retrieve all its methods, we have to use the following statements. But I think that both is a terrible way of wasting programming and run time.

<pre><code>assert isinstance(instanceX, ClassOfInstanceX) 
instanceX.{#list of method/properties appears}
</code></pre>

Alternatively, you can also use the class name will recall the method or property everytime you want to invoke it and pass in the instance to the self parameter. But this is too verbose, for my liking, esp for nested class

<pre><code>ClassOfInstanceX.{#list of method/properties appears}
 # then you will have...
ClassOfInstance.method(instanceX, args...)
</code></pre>

You can install the library via pyCharm "package manager".

Go to Settings -> Project Interpreter -> Python Interpreters

<img src="https://i.stack.imgur.com/IjnsS.png" alt="Package list">

And in the Packages list, click on install and search for the library you want to install

<img src="https://i.stack.imgur.com/HC8oc.png" alt="Install package">

Once installed, auto-complete will be available on editor.

Hope this is what you are looking for.

When I'm using a 3rd party l
ibrary such as <a href="http://code.google.com/p/boto/" rel="noreferrer">boto</a>, PyCharm seems to be able to auto-complete quite nicely

<img src="https://i.stack.imgur.com/rsKkH.png" alt="enter image description here">

However, as soon as I define a function of my own, auto-complete breaks down inside that function. I understand why, since I can't give the function any type information about its arguments, so it can't guess how to auto-complete. Is there a way around this issue?

Edit

I tried using the docstring (for Python 2), but still no auto-complete

<pre><code>def delete_oldest_backups(conn, backups_to_keep, backup_description):
 """
 delete_oldest_backups(EC2Connection, int, string)
 """
</code></pre>

(Also tried <code>boto.ec2.connection.EC2Connection</code> instead of just <code>EC2Connection</code>)

How to get PyCharm to auto-complete code in methods?
