  2. python, writing a newline character, the following error occurred: 
Traceback (most recent call last):

try this 


     f.write(u'\n') -sharp u  unicode

python2.7 does not have a default unicode encoding. Just convert it to unicode encoding. For example, print (upright ')

  1. when writing a string in a file, you can use: f.write (uplinn') u means to encode in Unicode

  2. python 2.7 does not have a default Unicode encoding, so you need to encode the elements yourself

  3. StrToUnicode using decode (); UnicodeToStr using encode ()
    example: 
    with io.open('xxxx', 'a') as f:
        for i in LIST:
            f.write(i.decode('utf-8','ignore'))
            f.write(u"\n")
