A str may have several valid encodings, and a bytes object may or may not Assuming Python 3 (in Python 2, this difference is a little less well-defined) - a string is a sequence of characters, ie unicode codepoints; these are an abstract concept, and can't be directly In this tutorial, you'll learn how to concatenate strings in Python. 7 output: In Python 3, the ‘b’ separator string prefix is 1 You're mixing up the representation of a byte array (which uses \x to show hex codes) and the actual byte values. Learn how to concatenate two bytes objects in Python using a simple program. While regular strings in Python are used to represent For packing, the string is truncated or padded with null bytes as appropriate to make it fit. x.
