python摆脱了unicode和`\\ r \\ n`字符

Question

I want to get rid `\\r\\n' characters in my string to do so, I tried this :

s1.translate(dict.fromkeys(map(ord, u"\n\r")))
    lists1=[]
    lists1.append(s1)
    print lists1

I received this:

[u'\r\nFoo\r\nBar, FooBar']

How can I get rid of \\r\\n characters in my string ?

Answer 1

Use str() and replace() to remove both u and \\r\\n :

In [21]: strs = u'\r\nFoo\r\nBar'

In [22]: str(strs).replace("\r\n","")
Out[22]: 'FooBar'

or just replace() to get rid of only \\r\\n :

In [23]: strs.replace("\r\n","")
Out[23]: u'FooBar'

Answer 2

cleaned = u"".join([line.strip() for line in u'\r\nFoo\r\nBar, FooBar'.split("\r\n")])

或只使用replace() ：

cleaned = u'\r\nFoo\r\nBar, FooBar'.replace("\r\n", "")

Answer 3

你可以做

'this is my string\r\nand here it continues'.replace('\r\n', '')
