Python根據兩個字符之間的字符串拆分

Question

如何根據字符串中的兩個字符"["和"]"進行分割。 例如，在下面調用.split（）會給出...

x = "[Chorus: Rihanna & Swizz Beatz]
I just wanted you to know
...more lyrics
[Verse 2: Kanye West & Swizz Beatz]
I be Puerto Rican day parade floatin'
... more lyrics"

x.split()
print(x)

會給

["I just wanted you to know ... more lyrics", " be Puerto Rican day parade floatin' ... more lyrics]

這與重復項不同，因為它不必被多個定界符分割，當不一定要知道文本時，可以被括在方括號中的文本分割...

Answer 1

您可以使用re.split("[\\[\\]]", x)

使用正則表達式：

import re
x = """[Chorus: Rihanna & Swizz Beatz]
I just wanted you to know
...more lyrics
[Verse 2: Kanye West & Swizz Beatz]
I be Puerto Rican day parade floatin'
... more lyrics"""

print(filter(None,re.split("[\[\]]", x)[::2]))

輸出：

['\nI just wanted you to know\n...more lyrics\n', "\nI be Puerto Rican day parade floatin'\n... more lyrics"]
