智能替换重复值python

python replace

智能替换重复值python,python,replace,Python,Replace,所以我有一个文件，我想逐行替换一些非常相似的单词，实际上其中一些是其他单词的子字符串： uint8=("UINT8 ","PIN_UINT8 ") uint16=("UINT16 ","PIN_UINT16 ") uint32=("UINT32 ","PIN_UINT32 ") uint64=("UINT64 ","PIN_UINT64 ") int8=("INT8 ","PIN_INT32 ") int16=("INT16 ","PIN_INT16 ") int32=("INT32 ","PI

所以我有一个文件，我想逐行替换一些非常相似的单词，实际上其中一些是其他单词的子字符串：

uint8=("UINT8 ","PIN_UINT8 ")
uint16=("UINT16 ","PIN_UINT16 ")
uint32=("UINT32 ","PIN_UINT32 ")
uint64=("UINT64 ","PIN_UINT64 ")
int8=("INT8 ","PIN_INT32 ")
int16=("INT16 ","PIN_INT16 ")
int32=("INT32 ","PIN_INT32 ")
int64=("INT64 ","PIN_INT64 ")
这些是替代品。但是我需要小心，因为
INT8
是
UINT8
的子字符串，所以即使我有匹配项，我也需要检查它是
UINT8
还是
INT8

我已经写了一些代码，但还远远不能工作

只需在int替换之前进行uint替换，它就可以工作了……也许可以使用正则表达式-
re
module@L3viathan将
INT8
更改为
PIN\u INT8
将
PIN\u UINT8
更改为
PIN\u UINT8
@furas啊，说得好，没想到。尝试
re.sub（r'（U？INT\d+？）'，r'PIN\U\1'，line）
。只需在INT替换之前进行uint替换，它就可以工作了…可能使用正则表达式-
