To convert byte strings to Unicode use the bytes. decode() method and use str. encode() to convert Unicode to a byte string. Both methods allow the character set encoding to be specified as an optional parameter if something other than UTF-8 is required.
decode() is used to decode bytes to a string object. Decoding to a string object depends on the specified arguments. It also allows us to mention an error handling scheme to use for seconding errors. Note: bytes is a built-in binary sequence type in Python.
In Python3, the default string is called Unicode string (u string), you can understand them as human-readable characters. As explained above, you can encode them to the byte string (b string), and the byte string can be decoded back to the Unicode string.
Using the string encode() method, you can convert unicode strings into any encodings supported by Python. By default, Python uses utf-8 encoding.
Method #2 : Using join() + format() + ord()
In this, task of substitution in unicode formatted string is done using format() and ord() is used for conversion.
UTF-16 is an encoding of Unicode in which each character is composed of either one or two 16-bit elements. Unicode was originally designed as a pure 16-bit encoding, aimed at representing all modern scripts.
Convert character to Unicode code point: ord()
By specifying a string of one character as an argument of ord() , the Unicode code point of the character is returned as an integer int . An error occurs if you specify a string of more than two characters. Unicode code points are often written in hexadecimal notation.
%s specifically is used to perform concatenation of strings together. It allows us to format a value inside a string. It is used to incorporate another string within a string. It automatically provides type conversion from value to string.
Single Post Underscore is used for naming your variables as Python Keywords and to avoid the clashes by adding an underscore at last of your variable name.
We can use the built-in Bytes class in Python to convert a string to bytes: simply pass the string as the first input of the constructor of the Bytes class and then pass the encoding as the second argument. Printing the object shows a user-friendly textual representation, but the data contained in it is in bytes.
+ 3. \x is used to denote an hexadecimal byte. \x00 is thus a byte with all its bits at 0.
UTF-8 is one of the most commonly used encodings, and Python often defaults to using it. UTF stands for “Unicode Transformation Format”, and the '8' means that 8-bit values are used in the encoding. (There are also UTF-16 and UTF-32 encodings, but they are less frequently used than UTF-8.)
One method is to create a string variable and then append the byte value to the string variable with the help of + operator. This will directly convert the byte value to a string and add it in the string variable. The simplest way to do so is using valueOf() method of String class in java.
To convert larger units to smaller units (i.e. take a number of gigabytes and convert it down in to megabytes, kilobytes, or bytes) you simply multiply the original number by 1,024 for each unit size along the way to the final desired unit.
Here's what python.org has to say about %i: Signed integer decimal. And %d: Signed integer decimal. %d stands for decimal and %i for integer.
%c represents character values. It's part of the integer representation types. You can't enter a value larger than an unsigned byte (255) as a positional argument to it, so be careful where and when you elect to use it.
To include Unicode characters in your Python source code, you can use Unicode escape characters in the form \u0123 in your string. In Python 2. x, you also need to prefix the string literal with 'u'.
Python chr() function is used to get a string representing of a character which points to a Unicode code integer. For example, chr(97) returns the string 'a'. This function takes an integer argument and throws an error if it exceeds from the specified range. The standard range of the argument is from 0 to 1,114,111.
Python chr() Python chr() function takes integer argument and return the string representing a character at that code point. Since chr() function takes an integer argument and converts it to character, there is a valid range for the input.
UTF-16 is based on 16-bit code units. Each character is encoded as at least 2 bytes. Some characters that are encoded with a 1-byte code unit in UTF-8 are encoded with a 2-byte code unit in UTF-16. Characters that are surrogate or supplementary characters use 4 bytes and thus require additional storage.
Unicode uses two encoding forms: 8-bit and 16-bit, based on the data type of the data that is being that is being encoded. The default encoding form is 16-bit, where each character is 16 bits (2 bytes) wide.
Likewise, UTF-16 is based on 16-bit code units. Therefore, each character can be 16 bits (2 bytes) or 32 bits (4 bytes). All UTFs include the full Unicode character repertoire , or set of characters.
