I've been looking through the Python Cookbook (2nd Edition) to learn how to process strings and characters.
I wanted to try converting a number into its Unicode equivalent. So I tried using the built-in function called 'unichr', which, according to the Cookbook, goes something like:
>>> print repr(unichr(8224)) ... and will output:
u'\u2020' However, the code failed. I thought it had something to do with print (because Python 3 uses print() instead of print ""), but that didn't work out as well. I tried several variations to the code, and it still failed. At long last, I just typed a simple line:
unichr(10000) To my surprise, this error message kept popping up, no matter what value I put into the above function:
NameError: name 'unichr' is not defined What could be the problem? Is there some specific module that I'm supposed to import?

In Python 3, there's no difference between unicode and normal strings anymore. Only between unicode strings and binary data. So the developers finally removed the unichr function in favor of a common chr which now does what the old unichr did. See the documentation here.
Python 3.x doesn't have a special Unicode string type/class. Every string is a Unicode string. So... I'd try chr. Should give you what unichr did pre-3.x. Can't test, sadly. Show activity on this post. In case you need to run in both python 2 and python 3, you can use this common syntax (the unused syntax would point to the new one)

In Python 3, you just use chr:
>>> chr(10000) '✐' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
