python把汉字字符串中的'\n‘去掉

Question

从文件中读出的一个汉字字符串用这个句话判断是否包含回车：pythonif'\n'inmystring:printtype(mystring)#mystring.replace('\n','')#doesnotworkmystring.replace(u'\n',u'')#doesnotworkmystring.encode("gbk")mystring.replace("\n","")#doesnotworkmystring.encode("utf-8")mystring.replace("\n","")#doesnotworkmystring.encode("ascii")mystring.replace("\n","")#UnicodeEncodeError:'ascii'codeccan'tencodecharactersinposition0-20printmystring这该如何是好？请指教！

Answer 1

我想到的是，既然是从文件读入的，那为什么不用strip呢？
pythonfile=open('file.txt','rt')
forlineinfile:
line=line.strip()
                            

Answer 2

字符串的replace方法不会修改原字符串的内容
尝试
a="woshishazi\n!!!"
a=a.replace('\n','')
