Python 正则表达式 : Find all caps with no following lowercase

Question

如果后续字符不是小写，我如何保留所有大写字符？

考虑这个例子:

import re
test1 = 'ThisIsATestTHISISATestTHISISATEST'

re.findall(r'[A-Z]{2}[^a-z]+', test1)
# ['THISISAT', 'THISISATEST']

期望: 这:'THISISAT'，应该读作:'THISISA'

Answer 1

尝试(regex101):

import re

test1 = "ThisIsATestTHISISATestTHISISATEST"

print(re.findall(r"[A-Z]{2}[A-Z]*(?![a-z])", test1))

打印:

['THISISA', 'THISISATEST']
