Using python I'm parsing several strings. Sometimes the string has appended several semicolons to it.
使用python我正在解析几个字符串。有时字符串会附加几个分号。
Example strings:
s1="1;Some text"
s2="2;Some more text;;;;"
The number of appending semicolons varies, but if it's there it's never less than two.
The following pattern matches s1, with s2 it includes the appended semicolons.
How do I redo it to remove those?
附加分号的数量会有所不同,但如果它在那里则不会少于两个。以下模式与s1匹配,s2包含附加的分号。如何重做以删除它们?
pat=re.compile('(?m)^(\d+);(.*)')

You can use the str.rstrip([chars])
你可以使用str.rstrip([chars])
This method returns a copy of the string in which all chars have been stripped from the end of the string (default whitespace characters).
此方法返回字符串的副本,其中所有字符都已从字符串末尾删除(默认空白字符)。
e.g. you can do:
例如你可以做:
s2 = s2.rstrip(";")
