Python program to print an array of bytes representing an integer

Python example of int.to_bytes() strategy: Here, we will figure out how to change over a given number into a byte exhibit? Given an integer number and we need to change over it into a byte cluster in Python. To change over an integer number into bytes (byte cluster), we use to_bytes() strategy for int class, it is called with the number with three contentions and returns a byte exhibit speaking to the number. Syntax: int.to_bytes(size, byteorder) Here, size is the most extreme size (in bytes) of the number. byteorder is the method to print the bytes, it has two values huge to print bytes cluster in large endian configuration and little to print bytes exhibit in a little-endian group. Example: Input: num = 100 # function call print(num.to_bytes(2, byteorder ='big')) Output: b'\x00d' Python code to change over an integer number to bytes exhibit: # Python program to find number of bits # necessary to represent an integer in binary # input a number num = int(input("Enter an integer number: ")) # total bits to represent number bits = num.bit_length() print("bits required to store ", num, " = ", bits) print("binary value of ", num, " is = ", bin(num)) Output: First run: Enter an integer number: 67 bits required to store 67 = 7 binary value of 67 is = 0b1000011 Second run: Enter an integer number: 3 bits required to store 3 = 2 binary value of 3 is = 0b11 In the event, that number is longer than 2 bytes value, In the event that the info number is bigger than 2 bytes and we utilized size "2 bytes" with the to_bytes() technique, at that point an "OverflowError" mistake ("int too huge to change over") will happen. Enter an integer number: 12387615 Traceback (most recent call last): File "/home/main.py", line 8, in x = num.to_bytes(2, byteorder ='big') OverflowError: int too big to convert to_bytes() exhibit with size "4 bytes" In the past example, we utilized size "2 bytes", if the number is bigger than it, we can build the size. Here, in this example – we are utilizing size "4 bytes", hence, we can change over an integer till 4 bytes. # Python program to print an array of bytes # representing an integer # input an integer number num = int(input("Enter an integer number: ")) # finding the byte array x = num.to_bytes(4, byteorder ='big') # printing byte array print("x = ", x) Output: First run: Enter an integer number: 12387615 x = b'\x00\xbd\x05\x1f' Second run: Enter an integer number: 9999876 x = b'\x00\x98\x96\x04' Printing the bytes exhibit in little-endian design: To print bytes cluster of an integer number, we can characterize byteorder value with pretty much nothing. In this example, we are changing over an integer number (till 4 bytes) to bytes cluster in the little-endian request. # Python program to print an array of bytes # representing an integer # input an integer number num = int(input("Enter an integer number: ")) # finding the byte array x = num.to_bytes(4, byteorder ='little') # printing byte array print("x = ", x) Output: First run: Enter an integer number: 12387615 x = b'\x1f\x05\xbd\x00' Second run: Enter an integer number: 9999876 x = b'\x04\x96\x98\x00'
