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

Origin of the phrase “under your belt”?

Image
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0; } 17 1 Today, I found myself discussing what students should have "under their belts" during a lecture, and I wondered to myself if there was some inappropriate undertone here that I might be unaware of. Question : What is the origin of the phrase "under your belt"? A google search revealed some webpages (e.g. [1]) that assert its origin is related to consumption of food -- once a meal has been eaten, it's under your belt (which is a relief). However, with such websites, I have no way to determine fact from "random guy on the internet making stuff up". etymology idioms ...
