在大写/小写边界处拆分字符串

Question

我想在大/小写的边界分割下面的字符串。我如何在Python和/或正则表达式中执行此操作？

例如，

x = 'aagaaggagatataccATGAATTTGTCGGTTTACCCCAATTTAACCAAAgaaaacctgtacaa'

split_boundaries(x) = ['aagaaggagatatacc', 
                       'ATGAATTTGTCGGTTTACCCCAATTTAACCAAA',
                       'gaaaacctgtacaa']

Answer 1

使用re.findall：

import re
x = 'aagaaggagatataccATGAATTTGTCGGTTTACCCCAATTTAACCAAAgaaaacctgtacaa'

re.findall(r'[a-z]+|[A-Z]+', x)
# ['aagaaggagatatacc', 'ATGAATTTGTCGGTTTACCCCAATTTAACCAAA', 'gaaaacctgtacaa']
