How do you find the encoding of a string in python?
In this tutorial, we will learn about the Python String encode() method with the help of examples. Show
The Example
Syntax of String encode()The syntax of string.encode(encoding='UTF-8',errors='strict') String encode() ParametersBy default, the It returns an utf-8 encoded version of the string. In case of failure, it raises a However, it takes two parameters:
Example 1: Encode to Default Utf-8 Encoding
Output The string is: pythön! The encoded version is: b'pyth\xc3\xb6n!' Example 2: Encoding with error parameter
Output The string is: pythön! The encoded version (with ignore) is: b'pythn!' The encoded version (with replace) is: b'pyth?n!' Note: Try different encoding and error parameters as well. String EncodingSince Python 3.0, strings are stored as Unicode, i.e. each character in the string is represented by a code point. So, each string is just a sequence of Unicode code points. For efficient storage of these strings, the sequence of code points is converted into a set of bytes. The process is known as encoding. There are various encodings present which treat a string differently. The popular encodings being utf-8, ascii, etc. Using the string What do I have to do in Python to figure out which encoding a string has?

2 In Python 3, all strings are sequences of Unicode characters. There is a In Python 2, a string may be of type
This does not distinguish "Unicode or ASCII"; it only distinguishes Python types. A Unicode string may consist of purely characters in the ASCII range, and a bytestring may contain ASCII, encoded Unicode, or even non-textual data.

MikelMikel 24k8 gold badges63 silver badges66 bronze badges 5 In python 3.x all strings are sequences of Unicode characters. and doing the isinstance check for str (which means unicode string by default) should suffice.
With regards to python 2.x, Most people seem to be using an if statement that has two checks. one for str and one for unicode. If you want to check if you have a 'string-like' object all with one statement though, you can do the following:

Have a read of McMillan's Unicode In Python, Completely Demystified talk from PyCon 2008, it explains things a lot better than most of the related answers on Stack Overflow. answered May 21, 2012 at 14:12

An extremely ugly one is to compare the name of the type, instead of comparing the type itself. Here's an example:
An arguably slightly less ugly workaround is to check the Python version number, e.g.:
Those are both unpythonic, and most of the time there's probably a better way. answered Aug 14, 2012 at 12:33

Python's Even on Python 3, it's not as simple to answer this question as you might imagine. An obvious way to test for ASCII-compatible strings is by an attempted encode:
The error distinguishes the cases. In Python 3, there are even some strings that contain invalid Unicode code points:
The same method to distinguish them is used. answered Jul 9, 2014 at 2:35
VeedracVeedrac 55.5k14 gold badges108 silver badges165 bronze badges 0 This may help someone else, I started out testing for the string type of the variable s, but for my application, it made more sense to simply return s as utf-8. The process calling return_utf, then knows what it is dealing with and can handle the string appropriately. The code is not pristine, but I intend for it to be Python version agnostic without a version test or importing six. Please comment with improvements to the sample code below to help other people.

1 You could use Universal Encoding Detector, but be aware that it will just give you best guess, not the actual encoding, because it's impossible to know encoding of a string "abc" for example. You will need to get encoding information elsewhere, eg HTTP protocol uses Content-Type header for that.

Code : encoding. convert(string) to convert the encoding.. Code : Example.. Output :. detect() : It is a charade. detect() wrapper. It encodes the strings and handles the UnicodeDecodeError exceptions.. What encoding is this string Python?Since Python 3.0, strings are stored as Unicode, i.e. each character in the string is represented by a code point. So, each string is just a sequence of Unicode code points. For efficient storage of these strings, the sequence of code points is converted into a set of bytes.
What is the encoding of a string?String objects use UTF-16 encoding. The problem with UTF-16 is that it cannot be modified. There is only one way that can be used to get different encoding i.e. byte[] array.
Why encode () is used in Python?Definition. The Python encode() is a built-in string method that is used to return an encoded version of the string according to the encoded standard. Python encode() string function is used to secure the string by encoding it based on the specified encoding type.
