What is bytes like object in python?
I've very recently migrated to Python 3.5. This code was working properly in Python 2.7: Show
After upgrading to 3.5, I'm getting the:
The error is on the last line (the pattern search code). I've tried using the

As the error describes, in order to write a string to a file you need to encode it to a byte-like object first, and answered May 22, 2016 at 16:17
4 Like it has been already mentioned, you are reading the file in binary mode and then creating a list of bytes. In your following for loop you are comparing string to bytes and that is where the code is failing. Decoding the bytes while adding to the list should work. The changed code should look as follows:
The bytes type was introduced in Python 3 and that is why your code worked in Python 2. In Python 2 there was no data type for bytes:

After changing this, the error disappears, but you can't write to the file (in my case). So after all, I don't have an answer? Source: How to remove ^M Changing to 'rb' brings me the other error: io.UnsupportedOperation: write

Ibrahim.HIbrahim.H 9121 gold badge12 silver badges19 bronze badges 1 What is a bytes in Python?Python bytes() We utilize the Python bytes() method to manipulate binary data in the program. The byte is a digital information unit that typically consists of 8 bits each of which consists of a 0 or 1. A byte is a computer architecture term for memory storage that encodes a single character of text in a computer.
How do you fix a bytesTo solve the Python "TypeError: a bytes-like object is required, not 'str'", encode the str to bytes, e.g. my_str. encode('utf-8') . The str. encode method returns an encoded version of the string as a bytes object.
What are byte strings in Python?In Python, a byte string is just that: a sequence of bytes. It isn't human-readable. Under the hood, everything must be converted to a byte string before it can be stored in a computer. On the other hand, a character string, often just called a "string", is a sequence of characters. It is human-readable.
Does Python have byte?Python bytes() Function
It can convert objects into bytes objects, or create empty bytes object of the specified size. The difference between bytes() and bytearray() is that bytes() returns an object that cannot be modified, and bytearray() returns an object that can be modified.
