使用正则表达式在字符串中排列未格式化的段落

我有一篇没有安排好的文章,比如说

randstr='''
Hello Abou al Reeem
HAbibi abou lbeess
dkhlak 3amak l khil wen
Li aslan 7adan be3rif shi 3an l bazz ? 
Sara7a wala 7adan by3rif 3an l ken3an

Grave is 22 and Tony is 15
Rami is 44 and Aya is 40
'''

如你所见,第一段由以下句子组成: \n 不同的线条。我想要的是用python编写代码,这样我就可以得到这个

list='''
 Hello Abou al Reeem HAbibi abou lbeess dkhlak 3amak l khil wen Li aslan 7adan be3rif shi 3an l bazz ?  Sara7a wala 7adan by3rif 3an l ken3an

 Grave is 22 and Tony is 15 Rami is 44 and Aya is 40
'''

我在python代码方面取得了一定的成功

import re
randstr='''
Hello Abou al Reeem
HAbibi abou lbeess
dkhlak 3amak l khil wen
Li aslan 7adan be3rif shi 3an l bazz ? 
Sara7a wala 7adan by3rif 3an l ken3an

Grave is 22 and Tony is 15
Rami is 44 and Aya is 40
'''

# Split the string based on empty lines (Note: I tried ^\s*$ but it did not work)
A=randstr.split('\n\n')

# Split each of the elements in A to one sentence without the \n using regular expression substitution
regex=re.compile('\n')

for i in range(len(A)):
    A[i]=regex.sub(' ',A[i])

A

但我想知道这是否更容易,是否可以在Sublime文本3中而不是在python中这样做?

注意:我不熟悉正则表达式
