Python bytearray() Function
The bytearray() function in Python returns a bytearray object or
converts any object into a bytearray object. For example:
x = bytearray()
print(type(x))
print(bytearray(5))
a = "codescracker"
x = bytearray(a, "utf-8")
print(x)
b = "python"
b = bytearray(b, "utf-16")
print(b)
The snapshot given below shows the sample output produced by above Python program, demonstrating the bytearray()
function:
Note: Unlike bytes(), bytearray() returns an object that can
be modified.
Python bytearray() Function Syntax
The syntax of bytearray() function is:
bytearray(x, encoding, error)
where x refers to the source. If the source is an integer type, then an empty bytearray object with specified
size, with given x integer value, will get created. The encoding is needed when x is of
string type. The error is used when the encoding fails or mismatched.
All the three parameters are optional.
Note: We can use string, integer, iterable, or object type as value of x.
Python bytearray() Function Example
Here is a simple example of bytearray() function in Python:
mylist = [3, 6, 8, 2]
ba = bytearray(mylist)
print(ba)
mystr = "codes cracker dot com"
ba = bytearray(mystr, "utf-8")
print(ba)
mysize = 10
ba = bytearray(mysize)
print(ba)
The sample output of this program, is shown in the snapshot given below:
