How to find whether an input string provided is a valid charset or not?

-1

Is there any way to check if the given string variable contains a valid charset name.

For Example:

input:

str = "utf-8"

#checking str, if valid charset name then return True



str= "abcd"

#checking str, if invalid charset name then return False

Is there any way to achieve that?

First thing. Please don't use str as variable name as it is a built in Python function.

I read your question as wanting to validate that a string is a valid encoding name. codecs.lookup(encoding) can do that:

>>> import codecs

>>> codecs.lookup('utf-8')

<codecs.CodecInfo object for encoding utf-8 at 0x1e7c42905e8>

>>> codecs.lookup('abcd')

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

LookupError: unknown encoding: abcd

So you could use:

def validate(name):

    try:

        codecs.lookup(name)

        return True

    except LookupError:

        return False
