Unicode to String in Python

Python

Python is an interactive and more accessible language than any other programming language. The python programming language uses a variety of libraries to perform the operations in a faster way. The python language can also be used in web development; Django and Flask are the frameworks used to create web applications using Python.

In Python, indentation is the main concept; if we do not follow proper indentation, the Code may not run. We can easily create an application in Python if we are familiar with indentation, Variables, Operators, loop concepts and function concepts in python language.

String in Python

The string is a primitive data type in a python programming language; Python does not contain the character data type. The string of length is considered as the character. The string is generally the collection of characters enclosed within a single, double, or triple quote. The strings in Python are “immutable”; we cannot change a string once they are created.

In Python, whatever data we take as input will be read as a string. In Python, string concatenation is possible; we can print the addition of two strings. In a python programming language, when we give any data as the input, it will take the input as a string to convert the given data into our required data type; we need to use the method of type conversion.

Example:

string = input()
print(string)

Output:

Immutable

Unicode

The Unicode is the description of every character used by the human, and the Unicode gives a unique code to each character so that the computer can easily understand it. Generally, the English alphabets are given a unique code ranging from 0 to 0x10FFFF based on the ASCII values.

The character is the shortest component of the text; the character is also a sting in the python programming language, with the length of the string as ‘one’. Let us now look at some of the ASCII( American Standard Code For Information Interchange ) code values of the English alphabet.

Letter	ASCII Code	Binary	Letter	ASCII Code	Binary
a	097	01100001	A	065	01000001
b	098	01100010	B	066	01000010
c	099	01100011	C	067	01000011
d	100	01100100	D	068	01000100
e	101	01100101	E	069	01000101
f	102	01100110	F	070	01000110
g	103	01100111	G	071	01000111
h	104	01101000	H	072	01001000

Unicode to String Python

The characters in the English language are converted into ASCII values so that these characters can be understood by the computer based on the Unicode values. The python programming language provides some methods or functions like the str( ) method, which converts Unicode values into the string.

Str( ) function:

The str( ) function is used to convert the Unicode values into the normal string with the help of thestr( ) function. But here, we need to give the Unicode values only in the form of the ASCII characters; if the Unicode character contains other characters than the ASCII characters, the str( ) function will not operate and raise an error.

Example:

#input the Unicode string
unicode_str = u “Python”
#Calling the str( ) function, which will convert a Unicode string into a normal string
nor_string = str(unicode_str)
#Displaying the converted string
print(nor_string)

Output:

Python

Here, we can observe that the str( ) function has converted the Unicode text into the normal string. Here we can also input the Unicode string in the form of a file for this; first, we need to write the Unicode strings into the file, then we need to encode the strings, and when we need to use these Unicode strings, we need to decode the file there are different types of Unicode encoding techniques such as UTF-8, UTF-3 and many more.

Now let us consider an example of inputting the Unicode data in the form of  a file and decoding it with the UTF-8 technique

Example:

#Input the Unicode string
unicode_string = u ‘ & 20’
#Encoding the Unicode string
encode_string = unicode_str.encode( ‘UTF-8’)
#Then, finally decoding the data
dec_string = encode_string.decode( ) 
#Displaying the string
print(dec_string )

Output:

b ‘\xc3\xa234
&20

Here we can observe that first, we need to encode the string, then we need to decode it for further use of the string. To decode the file, there are different types of Unicode encoding techniques such as UTF-8, UTF-3 and many more.
