How to convert Bytes to string in Python

string1 = 'Welcome to JavaTpoint'  
print(type(string1))  
string2 = b'Welcome to JavaTpoint'  
print(type(string2))  

Output:

<class 'str'>
<class 'bytes'>

Explanation

We define two strings with the same value. Both values are looking similar, but the data types are not same. The first string1 variable is a string data type, and the other is a byte data type. The second string2 variable is prefixed with 'b,' which means it produces the byte data type instead of the str data type.

The difference between these two data types is

Str - A string is a sequence of Unicode characters (encoded in UTF -16 or UTF-32 and entirely depends on Python's compilation).

Bytes or byte - It represents an integer between 0 and 255, and we can denote it as 'b' or 'B.'

We can convert any string to bytes by writing 'be literal in front of a regular string.

Note - Python 2.x ignores the prefix 'b' or 'B.'

Key Difference between String and Bytes

Both str and bytes data types are used as Byte type objects in Python 2.x, but it is not true in the case of Python 3.x. The critical difference between bytes and string is that strings are easy to read or human-readable where a byte is eventually machine-readable, and the string is also converted into byte before processing.

When we declare a byte data type in Python, it is directly stored in the disk and a string is converted into a byte and then stored on disk.

Strings are used to signify the characters, words, or sentences, whereas Bytes represent low-level binary data structures.

Convert Bytes to String in Python

• Using the decode() method

Python provides the built-in decode() method, which is used to convert bytes to a string. Let's understand the following example.

Example -

byteData = b"Lets eat a \xf0\x9f\x8d\x95!"  
# Let's check the type  
print(type(byteData))  
str1 = byteData.decode('UTF-8')  
print(type(str1))  
print(str1)  

Output:

<class 'bytes'>
<class 'str'>
Lets eat a
