Python string encode

Question

I have this code

att=att.replace("à","a")

but I received this error...

  att=att.replace("à","a")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

How can I fix?

You can decode them. att=att.decode('utf-8').replace("à".decode('utf-8'),"a") — Bhargav Rao

Don't mix unicode with byte strings. Python2 does implicit conversion, but Python3 does not. Even if you are not using Python3, it is good practice to avoid mixing the two.

In Python2, if att is a unicode, then

att.replace("à","a")

will implicitly try to decode "à" and "a"to be unicode as well before attempting to replace "à" in att. Python2 uses ascii (by default) to do the implicit decoding.

"à".decode('ascii') raises UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128).

To fix this error, since att is unicode, att.replace's arguments should be unicode as well:

att.replace(u"à",u"a")
