python拆分字符串，按空格和换行符

Question

I have this code:

f1=open('test.txt','r')
d={}
line = f1.read().replace('\n',' ')
line2= line.split("\n")

line = "This is line1\\nthis isline2\\nthis is line3"

My question is: can I do a split with multiple delimiters rather than replace first, then do a split?

Answer 1

Use re.split() .

Splitting on \\n and \\t :

In [23]: line = "This is line1\nthis isline2\tthis is line3"

In [24]: re.split(r'[\n\t]', line)
Out[24]: ['This is line1', 'this isline2', 'this is line3']
