python - 在命令行中粘贴格式化的 Python 代码

Question

我想从Anaconda shell中的示例运行 Python 代码。不幸的是，我要粘贴的语句以. 有没有一种简单的方法来运行这样的语句而无需手动删除？我知道存在其他 shell，但我不想让它们与 Anaconda 一起使用......

>>> features  = array([[ 1.9,2.3],
...                    [ 1.5,2.5],
...                    [ 0.8,0.6],
...                    [ 0.4,1.8],
...                    [ 0.1,0.1],
...                    [ 0.2,1.8],
...                    [ 2.0,0.5],
...                    [ 0.3,1.5],
...                    [ 1.0,1.0]])

Python 的原生doctest 解析器用于处理那些讨厌的 repr 提示。:)

>>> from doctest import DocTestParser
>>> repr_code = '''
... >>> features  = array([[ 1.9,2.3],
... ...                    [ 1.5,2.5],
... ...                    [ 0.8,0.6],
... ...                    [ 0.4,1.8],
... ...                    [ 0.1,0.1],
... ...                    [ 0.2,1.8],
... ...                    [ 2.0,0.5],
... ...                    [ 0.3,1.5],
... ...                    [ 1.0,1.0]])
... '''
>>> p = DocTestParser()
>>> code = next(filter(None, p.parse(repr_code.strip()))) # Filter out the useless parts
>>> print(code.source)
features  = array([[ 1.9,2.3],
               [ 1.5,2.5],
               [ 0.8,0.6],
               [ 0.4,1.8],
               [ 0.1,0.1],
               [ 0.2,1.8],
               [ 2.0,0.5],
               [ 0.3,1.5],
               [ 1.0,1.0]])
>>> array = list # Because it's cheaper than numpy
>>> exec(code.source) # If you're feeling very lucky...
>>> len(features)

据我正确理解你：你想删除点。我会这样做：

1. 打开vim
2. 按i
3. 粘贴文本 ( ctrl+v)
4. 按ESC退出Insert mode
5. 按ctrl+v进入Visual Block
6. 向上移动光标以选择所有点
7. 按x删除它们。

比用这个格式化的文本做任何你想做的事情（可以复制和粘贴）
