In Python, we have a wide variety of data types that can store and manipulate information in different ways. This guide will explain Complex numbers and Byte types (like bytes
, bytearray
, and memoryview
) in Python, using simple language and examples.
We’ll also see how to display this information on a WordPress website with code examples and sample outputs.
1. Complex Numbers in Python
A complex number is a number that has two parts:
- Real part (a regular number like 3 or -1)
- Imaginary part (a number that is multiplied by the imaginary unit
j
)
In Python, complex numbers are written like this:
a + bj
Where a
is the real part and b
is the imaginary part.
Example:
# Defining a complex number
my_complex_number = 3 + 4j
# Accessing the real part and imaginary part
print("Real part:", my_complex_number.real) # Output: 3.0
print("Imaginary part:", my_complex_number.imag) # Output: 4.0
Sample Output:
Real part: 3.0
Imaginary part: 4.0
2. Byte Types in Python
Byte types are used to handle data in binary format, which is especially useful when working with files, network data, or other low-level operations.
There are three types of byte data in Python:
bytes
bytearray
memoryview
Let’s go through each of them one by one.
2.1 bytes
bytes
is an immutable sequence of bytes. You can’t change a bytes
object once it’s created.
Example:
# Creating a bytes object
my_bytes = bytes([65, 66, 67, 68])
# Printing the bytes object
print(my_bytes) # Output: b'ABCD'
Sample Output:
b'ABCD'
2.2 bytearray
bytearray
is similar to bytes
, but it’s mutable, meaning you can change the data inside it after it’s created.
Example:
# Creating a bytearray object
my_bytearray = bytearray([65, 66, 67, 68])
# Modifying a value in the bytearray
my_bytearray[1] = 90 # Change the second byte to 'Z'
# Printing the updated bytearray
print(my_bytearray) # Output: bytearray(b'AZCD')
Sample Output:
bytearray(b'AZCD')
2.3 memoryview
A memoryview
allows you to view and work with byte data without making a copy. It’s like a window that shows part of the data, and you can manipulate it directly.
Example:
# Creating a memoryview from a bytearray
my_bytearray = bytearray([65, 66, 67, 68])
memory = memoryview(my_bytearray)
# Accessing the first byte
print(memory[0]) # Output: 65
# Changing the first byte through memoryview
memory[0] = 90
# Printing the modified bytearray
print(my_bytearray) # Output: bytearray(b'ZBCD')
Sample Output:
65
bytearray(b'ZBCD')
