正则表达式将子模式“hello1，2，3”替换为“hello”，而不影响其他编号模式

Question

抱歉，我对正则表达式没有经验

我想去掉字符串中的所有子模式，这些子模式的特点是在单词（'hello1'）后面有一个数字，或者在单词（'hello1，2，3'）后面有一系列数字，并用原来的单词（hello）替换这个模式。你知道吗

下面是我的文字：

x='interspersed by 1,6-hexanediol, corresponds to the immobile component observed with FRAP. Consistent with this idea, the immobile fraction of HP 1a.... own to arise through phase separation23. N&B analysis of GFP–fibrillarin highlighted areas of consistently high variance (2.38 ± 0.46 -mers) at the nucleolar boundary, compared to inside (1.28 ± 0.36) or outside (1.17 ± 0.25) the domain24, 25, 26. Similarly, GFP–HP 1a displayed increased variance34, 37'

x =re.sub(r'([^ 0-9])(\d+(?:, \d+)*)', r'\1', x)

在上面，我使用正则表达式来消除一个单词前面带有数字的模式，但是它也会产生不想要的效果：

interspersed by 1,-hexanediol, corresponds to the immobile component observed with FRAP. Consistent with this idea, the immobile fraction of HP 1a.... own to arise through phase separation. N&B analysis of GFP\xe2\x80\x93fibrillarin highlighted areas of consistently high variance (.\xe2\x80\x89\xc2\xb1\xe2\x80\x89. -mers) at the nucleolar boundary, compared to inside (.\xe2\x80\x89\xc2\xb1\xe2\x80\x89.) or outside (.\xe2\x80\x89\xc2\xb1\xe2\x80\x89.) the domain. Similarly, GFP\xe2\x80\x93HP 1a displayed increased variance

预期输出为：

x='interspersed by 1,6-hexanediol, corresponds to the immobile component observed with FRAP. Consistent with this idea, the immobile fraction of HP 1a.... own to arise through phase separation. N&B analysis of GFP–fibrillarin highlighted areas of consistently high variance (2.38 ± 0.46 -mers) at the nucleolar boundary, compared to inside (1.28 ± 0.36) or outside (1.17 ± 0.25) the domain. Similarly, GFP–HP 1a displayed increased variance'

保留“1,6-己二醇”、“1.28± 0.36”和“HP 1a”等模式，而不删除数字

更新：

这个表达式似乎无法完全摆脱包含连字符的模式（例如word11-12）。你知道吗

x='than allelic variant and define eQTLs9–11'

x = re.sub(r"(?<=\w)\d+(?:, \d+)*", "", x)

结果

than allelic variant and define eQTLs–1

预期产量：

than allelic variant and define eQTLs

有人能帮我做到这一点吗？你知道吗

Answer 1

x = re.sub(r"(?<=\w)\d+(?:, \d+)*", "", x)

说明

(?<=...)是一个积极的回顾。它基本上是说“确保这是在这里，没有实际匹配它”。如果需要，还可以用普通组替换它，并在替换中使用\1。你知道吗

\w匹配“word”字符。这通常相当于[a-zA-Z_]。你知道吗

\d+匹配一个数字。你知道吗

(?:, \d+)*匹配逗号，后跟空格，后跟数字，零次或多次。你知道吗
