我要對一個字符串做split
代碼如下
2
415import re
x = re.split(r"(?<=,)","a,b,c,")
print x輸出的結果是：
['a,b,c,']
而我希望的結果是：
['a,','b,','c,']
等效的perl寫法：
use Data::Dumper;
@x = split(/(?<=,)/,"a,b,c,");
print Dumper \@x結果：
$VAR1 = [
'a,',
'b,',
'c,'
];

# Note that split will never split a string on an empty pattern match. For example:
>>> re.split('x*', 'foo')
['foo']
>>> re.split("(?m)^$", "foo\n\nbar\n")
['foo\n\nbar\n']
