unicode text file

[Junaid]

I want to do replacements in a utf-8 text file. example

f=open("test.txt","r") #this file is uft-8 encoded

raw = f.read()
txt = raw.decode("utf-8")

txt.replace{'English', ur'ഇംഗàµà´²àµ€à´·àµ') #replacing raw unicode string,
but not working

f.write(txt)
f.close()
f.flush()


please, help me

Does
txt.replace('English', ur'ഇംഗàµà´²àµ€à´·àµ')
instead of
txt.replace{'English', ur'ഇംഗàµà´²àµ€à´·àµ')

fix the problem?

f.write(txt)

f.flush()

The file will be flushed when it's closed, and flushing it after closing
is meaningless.

You can use the codecs module to open and decode the file in one step

txt.replace{'English', ur'ഇംഗàµà´²àµ€à´·àµ') #replacing raw unicode string,
but not working

The replace method returns the altered string. It does not modify it in
place. You also should use Unicode strings for both the arguments (although
it doesn't matter in this case). Using a raw Unicode string is also
unnecessary in this case.

txt = txt.replace(u'English', u'ഇംഗàµà´²àµ€à´·àµ')

f.write(txt)

You opened the file for writing. You'll need to close the file and reopen
it for writing.

f.close()
f.flush()

Flush isn't required. close() will flush.

Also to have text like ഇംഗàµà´²àµ€à´·àµ in a file you'll need to declare the
encoding of the file at the top and be sure to actually save the file in the
encoding.

In summary:

# coding: utf-8
import codecs
f = codecs.open('test.txt','r','utf-8')
txt = f.read()
txt = txt.replace(u'English', u'ഇംഗàµà´²àµ€à´·àµ')
f.close()
f = codecs.open('test.txt','w','utf-8')
f.write(txt)
f.close()
