As we can see, it doesn’t matter whether it’s a string containing all Latin characters or otherwise, because strings in Python 3.x will all behave this way (and unlike in Python 2.x you can type any character into the IDLE window!). If you have dealt with encoding and Decoding Strings in Python 2.x, you know that they can be a lot more troublesome to deal with, and that Python 3.x makes it

Python Server Side Programming Programming We can use ast.literal_eval() here to evaluate the string as a python expression. It safely evaluates an expression node or a string containing a Python expression.The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

You can use the functions int and float to convert to integers or floating point numbers. The value “1234” is a string, you need to treat it as a number – to add 1, giving 1235. .

Hi! I have a C module for which I created a wrapper with swig. The function def is: C: int some_thing(unsigned char * the_str); eg: Python: some_module.some_thing (the_str) Now I would like to feed it with a UTF-8 formatted string: test = u’Make \u0633\u0644\u0627

Python has a built-in string class named “str” with many handy features (there is an older module named “string” which you should not use). String literals can be enclosed by either double or single quotes, although single quotes are more commonly used.

At the same time, you should encode Unicode back to the chosen character set right before presenting it to the user. It seems as if you have more control over string representation of objects in Python 2 because there’s no magic .__unicode__() method in

The string may contain any possible characters out of 256 valid ascii characters. Your algorithm should be generalized enough to work on any possible characters. Do not use class member/global/static variables to store states. Your encode and decode algorithms

I write a lot of ad-hoc protocol analysers using Python. Generally, I’m dealing with a byte stream that I want to output as a string of hex. Sometimes, I want to convert it back again. Eventually, I got round to putting the functions in a module so I wouldn’t keep cut and

I know in utf-8, this is suppose to be ideographic comma. The hexadecimal representation is 0xE38081. I know if I convert 0xE38081 to an

Edit: I checked the Python source. If you pass a unicode string to bytes using CPython, it calls PyUnicode_AsEncodedString, which is the implementation of encode; so you’re just skipping a level of indirection if you call encode yourself.
