Split text by paragraph

I have such a sample text,

 ## Paragraph 1\n\nThe [`sys`](https://docs.python.org/3.6/library/sys.html#module-sys) module also has attributes for *stdin*, *stdout*, and *stderr*. \n\nThe latter is useful for emitting warnings and error messages to make them visible even when *stdout* has been redirected:\n\n## Paragraph 2\n\nThe [`re`](https://docs.python.org/3.6/library/re.html#module-re) module provides regular expression tools for advanced string processing. For complex matching and manipulation, regular expressions offer succinct, optimized solutions:\n\nWhen only simple capabilities are needed, string methods are preferred because they are easier to read and debug.

I'd like to split it to two paragraphs using regex instead of str.split, so I tried.

In [18]: para = re.findall(r'## .+', content)
In [19]: para
Out[19]: ['## Paragraph 1', '## Paragraph 2']

The output I intent is separated complete paragraph.

['## Paragraph 1\n\nThe [`sys`](https://docs.python.org/3.6/library/sys.html#module-sys) module also has attributes for *stdin*, *stdout*, and *stderr*. \n\nThe latter is useful for emitting warnings and error messages to make them visible even when *stdout* has been redirected:\n\n',
'## Paragraph 2\n\nThe [`re`](https://docs.python.org/3.6/library/re.html#module-re) module provides regular expression tools for advanced string processing. For complex matching and manipulation, regular expressions offer succinct, optimized solutions:\n\nWhen only simple capabilities are needed, string methods are preferred because they are easier to read and debug.']

How to accomplish it?

You can try the inbuilt split function

string = '''I am new to python # please help me '''
data = string.split('#')
print(data)

Output

['I am new to python ', ' please help me ']

You can try this:

import re
s = " ## Paragraph 1\n\nThe [`sys`](https://docs.python.org/3.6/library/sys.html#module-sys) module also has attributes for *stdin*, *stdout*, and *stderr*. \n\nThe latter is useful for emitting warnings and error messages to make them visible even when *stdout* has been redirected:\n\n## Paragraph 2\n\nThe [`re`](https://docs.python.org/3.6/library/re.html#module-re) module provides regular expression tools for advanced string processing. For complex matching and manipulation, regular expressions offer succinct, optimized solutions:\n\nWhen only simple capabilities are needed, string methods are preferred because they are easier to read and debug."
paragraphs = re.split('\n(?=## Paragraph \d+)', s)

Output:

 [' ## Paragraph 1\n\nThe [`sys`](https://docs.python.org/3.6/library/sys.html#module-sys) module also has attributes for *stdin*, *stdout*, and *stderr*. \n\nThe latter is useful for emitting warnings and error messages to make them visible even when *stdout* has been redirected:\n', 
 '## Paragraph 2\n\nThe [`re`](https://docs.python.org/3.6/library/re.html#module-re) module provides regular expression tools for advanced string processing. For complex matching and manipulation, regular expressions offer succinct, optimized solutions:\n\nWhen only simple capabilities are needed, string methods are preferred because they are easier to read and debug.']
