By using from_bytes() function
The from_bytes() function is used to convert the specified byte string into its corresponding int values.
Syntax:
int.from_bytes(bytes, byteorder, *, signed=False)
Parameters: This function accepts some parameters which are illustrated below:
- bytes: A byte object
- byteorder: This parameter determines the order of representation of the integer value. byteorder can have values as either “little” where most significant bit is stored at the end and least at the beginning, or big, where MSB is stored at start and LSB at the end. Big byte order calculates the value of an integer in base 256.
- signed: Its default value is False. This parameter Indicates whether to represent 2’s complement of a number.
Return values: This function returns an int equivalent to the given byte.
Example: Python program to a byte string to a list of integers
Python3
# Python program to illustrate the# conversion of a byte string# to a list of integers# Initializing byte valuebyte_val = b'\x00\x01'# Converting to int# byteorder is big where MSB is at startint_val = int.from_bytes(byte_val, "big")# Printing int equivalentprint(int_val) |
Output:
1
Example 2: Python program to a byte string to a list of integers
Python3
# Python program to illustrate the# conversion of a byte string# to a list of integers# Initializing a byte stringbyte_val = b'\xfc\x00'# 2's complement is enabled in big# endian byte order formatint_val = int.from_bytes(byte_val, "big", signed="True")# Printing int objectprint(int_val) |
Output:
-1024
The time and space complexity of all the methods is same::
Time Complexity: O(n)
Auxiliary Space: O(n)
