问题
解决方案
- 用到了group提取
- 用到了.*?的非贪婪匹配（默认是贪婪匹配）
代码
In [35]: data = "HJ_2.5bb_BTN_Call_SB_Call_BB_14.0bb_HJ_FOLD_BTN_AllIn_SB_Call_BB_strategy.txt"
In [36]: r = re.match(r"(.*_)(.+?_FOLD_)(.*)", data)
In [37]: r.groups()
Out[37]:
('HJ_2.5bb_BTN_Call_SB_Call_BB_14.0bb_',
'HJ_FOLD_',
'BTN_AllIn_SB_Call_BB_strategy.txt')
In [38]: re.sub(r"(.*_)(.+?_FOLD_)(.*)", r"\1\3", data)
Out[38]: 'HJ_2.5bb_BTN_Call_SB_Call_BB_14.0bb_BTN_AllIn_SB_Call_BB_strategy.txt'
