Question

有没有办法将这个（像这样的jupyter notebook cells输出数组）提供给

[[[[ 54.88135039  71.51893664  60.27633761  54.4883183 ]

除了执行

之外，

进入np.array()

[[[[ 54.88135039,  71.51893664,  60.27633761,  54.4883183 ],

我使用sublime多个游标来添加逗号，但仍然很痛苦。

编辑：我看到这可以使用REGEX更快地完成，但它需要我在另一个单元格中单独完成。

为什么有人想这样做？

打印变量不再存在
从其他人的笔记本复制阵列时
从导出格式复制数组时

Answer 1

您可以使用regex执行此任务。

import re
s = "[[[[ 54.88135039  71.51893664  60.27633761  54.4883183 ]]]"
#replace the white space between two numbers with a comma
s = re.sub('((?<=\d)\s\s(?=\d))', r",\1", s)
#add a comma after each `]`
replaced = re.sub('(](?=\n))', r"\1,", s)

这应该用逗号替换数字之间的所有双白空格，并为所有行添加逗号（在每个]之后）。

编辑：但你为什么要这样做呢？您正在打印一个数组，并希望以后再次使用此打印数组？为什么不简单地使用您正在打印的阵列而不是打印它并解析打印输出？
