unicode table python

This example describes how Python reads and writes Unicode files. Share to everyone for your reference. The implementation method is as follows: #coding =utf-8 import OS import codecs def writefile (FN, V_ls): f = codecs.open (FN, ' WB ', ' Utf-8 ') for I in v_ls: f.write (i + os.linesep) f.close () def ReadFile (FN): f = codecs.open (FN, ' R ', ' Utf-8 ') ls = [Line.strip () For line in F]

OneCrawling web information in crawlers often requires converting a similar "\u4eba\u751f\u82e6\u77ed\uff0cpy\u662f\u5cb8" to Chinese, which is actually Unicode's Chinese encoding. The following methods can be used to convert:1.1 >>> s = u'\u4eba\u751f\u82e6\u77ed\uff0cpy\u662f\u5cb8'2 Print s 3 Life is short, py is shore2.1 >>> s = R'\u4eba\u751f\u82e6\u77ed\uff0cpy\u662f\u5cb8'2 >>> s = s.decode ('unicode_escape')3print s 4 Life is short, py is shoreTwoIn addition, the Python2 character enco

The path in Windows is a backslash \, but the backslash \ has the meaning of escape characters in Python, so when writing Windows file paths in a py file, pay special attention to the use of backslashes.Here are three ways to solve the problem: 1 way one: escaped by 2 3 c:\\users\xxx\desktop\a.txt " Span style= "COLOR: #008080" > 4 5 Mode two: explicitly declaring a string without escaping 6 7 r" c:\users\xxx\desktop\a.txt " 8
