Python codecs module---processing data when writing to a file there is a problem of encoding not uniform

The Open method opens the file sometimes with some problems, because the open opening file can only be written to the STR type, not the string encoding.

Example:

>>> FR = open (' test.txt ',' a ')

>>> line1 = "I love the Motherland"

>>> Fr.write (line1)

When there is a code is not unified, at this time to write open mode file is a problem.

>>> line2 = u ' I love the Motherland '

>>> Fr.write (line2)

Traceback (most recent):

File "<pyshell#4>", line 1, in <module>

Fr.write (line2) Unicodeencodeerror: ' ASCII ' codec Can ' t encode characters in Position 0-11:ordinal not in range

You can use Codecs.open,

>>> import codecs

>>> fw = Codecs.open ( ' Test1.txt ', ' a ', Utf-8 ')

>> > Fw.write (line2)
