Unicode (UTF-8) reading and writing to files in Python

Question

I\'m having some brain failure in understanding reading and writing text to a file (Python 2.4).

# The string, which has an a-acute in it.
ss = u\'Capit\\xe1         


        

Answer 1

except for codecs.open(), one can uses io.open() to work with Python2 or Python3 to read / write unicode file

example

import io

text = u'á'
encoding = 'utf8'

with io.open('data.txt', 'w', encoding=encoding, newline='\n') as fout:
    fout.write(text)

with io.open('data.txt', 'r', encoding=encoding, newline='\n') as fin:
    text2 = fin.read()

assert text == text2
