Nov 24, 2009 · If you want to store many of int or another C-like datatype, using a minimum of bytes, you can use the array class from the array module. if you want to know size of int, you can use struct. otherwise, as others already pointed out, use getsizeof (2.6). there is also a recipe you can try. In Python >= 2.6 you can use sys.getsizeof.

How can I find out the number of Bytes a certain integer number takes up to store? E.g. for hexadecimal \x00 - \xff (or decimal 0 - 255 = binary 0000 0000 - 1111 1111) I'm looking to get 1 (Byte),

Jan 2, 2025 · bytes () method in Python is used to create a sequence of bytes. In this article, we will check How bytes () methods works in Python. A string will be encoded into bytes using the specified encoding (default is ‘utf-8’). An iterable will have each element converted into bytes but it must have integers between 0 and 255.

Jul 27, 2021 · You can't do & on bytes type you need to convert it to int. For that you can do : int.from_bytes(your_bytes_value, byteorder='big') pos= int.from_bytes(b'\xff\xff', byteorder='big') & (recv_data[5] | (int.from_bytes(b'\xff\x00', byteorder='big') & (recv_data[6] << 8)))

Jun 4, 2023 · This concise article shows you a couple of different ways to get the size of a number (integer, float) in Python. If you mean the number of bytes needed to represent the number as a binary value, you can use the bit_length() method of integers and divide it by 8 (or use ceil division). Example: Output:

In this Python Tutorial, we learned how to find the length of bytes object using len () function, with example program. To find the length of a bytes object in Python, call len () builtin function and pass the bytes object as argument. len () function returns the number of bytes in the object.

Mar 5, 2025 · In this tutorial, you'll learn about Python's bytes objects, which help you process low-level binary data. You'll explore how to create and manipulate byte sequences in Python and how to convert between bytes and strings. Additionally, you'll practice this knowledge by coding a few fun examples.

Mar 17, 2025 · bit_length function returns the number of bits required to represent the number in binary format. Although we can represent any number with as the maximum number of bits as we want by adding leading zeros, it returns the number after excluding the leading zeros. It also ignores the bit used for sign representation.

Aug 20, 2020 · The task of converting bytes to bits in Python can be efficiently done by multiplying the number of bytes by 8, as 1 byte equals 8 bits. Additionally, methods like bit_length() and others can also be used to achieve this conversion.

Apr 21, 2025 · In Python, the .to_bytes() method is used to convert an integer into its byte representation. This is useful when weneed to store or transmit data in binary format. Example: Convert the integer 10 into bytes Python. num = 10 byte_data = num. to_bytes (2, 'big') print (byte_data) Output b'\x00\n'
