You can yank a paragraph with y}. This will not yank all the methods if you have a blank line though.

你可以用 猛拉一个段落y}。但是，如果您有一个空行，这不会删除所有方法。

If you want to yank everything except the {use yi{(or yi}). If you to include the curly braces use ya{(or ya}).

如果你想拉除{使用yi{（或yi}）之外的所有东西。如果要包含花括号，请使用ya{(或ya})。

The iand amodifiers mean inand all.

在i与a修饰符意味着在与所有。

To yank a word no matter where in the word you are: yiw

无论您在单词中的哪个位置，都要猛拉一个单词： yiw

To yank the contents of parentheses: yi); if you want to include them, use ya(

拉出括号的内容：yi); 如果要包含它们，请使用ya(

You can do the same for "or 'with yi", ya"or yi'and ya'.

您可以做同样的"或'与yi"，ya"或yi'和ya'。

Of course, you're not limited to yanking. You can delete a word with diwor change it with ciw, etc... etc...

当然，您不仅限于猛拉。您可以使用 删除diw或更改单词ciw，等等...等等...

There's a vim add-on script python_fn.vimwhich has, as one of its functions, a key binding to visually select a block of Python code using ]v. You could then yank it with yas normal.

有一个 vim 附加脚本python_fn.vim，它的功能之一是一个键绑定，可以使用]v. 然后你可以y像往常一样猛拉它。

I usually just use visual block mode. Shift-V, move, and 'y'ank the highlighted block. There's only so many shortcuts I can keep in memory at once :)

我通常只使用视觉块模式。Shift-V，移动并“y”ank 突出显示的块。我一次只能记住这么多快捷方式:)

1. Enter visual line selection by pressing 'V'
2. When finished selecting the block pres 'y'
3. Paste it somewhere with 'p' or 'P'

1. 按“V”进入视线选择
2. 完成选择块后按“y”
3. 用“p”或“P”将其粘贴到某处

You can combine a search with yank, so if your function ends with return retvalyou can type y/return retval

您可以将搜索与 yank 结合使用，因此如果您的功能以return retval您可以键入y/return retval

I made a plugin named spaceboxwhich does a Visual selection of all lines with the same or more indentation as the current line.

我制作了一个名为spacebox的插件，它对与当前行具有相同或更多缩进的所有行进行可视化选择。

With Python whitespace being the way it is, you could place your cursor on the line below defor if, and issue the command :SpaceBoxto select your "block".

由于 Python 空白就是这样，您可以将光标放在def或下方的行上if，然后发出命令:SpaceBox来选择您的“块”。

Just fold the class using za and then use visual mode ( V ) to select the collapsed class. This way you don't have to scroll too much. Then just yank with y. When you are done yanking unfold the class with za again.

只需使用 za 折叠类，然后使用视觉模式 ( V ) 选择折叠的类。这样你就不必滚动太多。然后用 y 猛拉。完成后，再次使用 za 展开类。
