以tr（“and end with”）开头的字符串的Python正则表达式

Question

我想用Python编写一个正则表达式，它将给出tr（“”）中包含的所有字符串。在

例如

str = 'According to some, dreams express tr("profound aspects of personality")' and 'tr("Foulkes 184"), though others disagree.'

所以我想要弦乐“人格的深刻方面”和“福克斯184”

有人能帮我吗？在

Answer 1

不需要向后/向前看，^{}中的一个简单组就足够了：

> s = 'According to some, dreams express tr("profound aspects of personality") "and" tr("Foulkes 184"), though others disagree.'
> re.findall(r'tr\("(.*?)"\)', s)
['profound aspects of personality', 'Foulkes 184']

来自findall文档：

If one or more groups are present in the pattern, return a list of groups.
