python正则表达式。提取模式之间的文本

如何获取下面“str”中“uniprotkb:”和“(gene name)”之间的所有值:

str = 'uniprotkb:HIST1H3D(gene name)|uniprotkb:HIST1H3A(gene name)|uniprotkb:HIST1H3B(gene name)|uniprotkb:HIST1H3C(gene name)|uniprotkb:HIST1H3E(gene name)|uniprotkb:HIST1H3F(gene name)|uniprotkb:HIST1H3G(gene name)|uniprotkb:HIST1H3H(gene name)|uniprotkb:HIST1H3I(gene name)|uniprotkb:HIST1H3J(gene name)'

结果是:

HIST1H3D
HIST1H3A
HIST1H3B
HIST1H3C
HIST1H3E
HIST1H3F
HIST1H3G
HIST1H3H
HIST1H3I
HIST1H3J

最佳答案

使用 re.findall()，您可以获得匹配正则表达式的字符串的所有部分:

>>> import re
>>> sstr = 'uniprotkb:HIST1H3D(gene name)|uniprotkb:HIST1H3A(gene name)|uniprotkb:HIST1H3B(gene name)|uniprotkb:HIST1H3C(gene name)|uniprotkb:HIST1H3E(gene name)|uniprotkb:HIST1H3F(gene name)|uniprotkb:HIST1H3G(gene name)|uniprotkb:HIST1H3H(gene name)|uniprotkb:HIST1H3I(gene name)|uniprotkb:HIST1H3J(gene name)'
>>> re.findall(r'uniprotkb:([^(]*)\(gene name\)', sstr)

['HIST1H3D', 'HIST1H3A', 'HIST1H3B', 'HIST1H3C', 'HIST1H3E', 'HIST1H3F', 'HIST1H3G', 'HIST1H3H', 'HIST1H3I', 'HIST1H3J']
