Python 3 makes a very strict distinction between text strings (characters) and binary data (bytes) A literal such as "hello" represents a text string stored as Unicode, whereas b"hello" represents a string of bytes (containing ASCII letters in this case) Under no circumstances can the str and bytes type be mixed in Python 3 For example, if you try to concatenate strings and bytes together, you will get a TypeError exceptionThis differs from Python 2 where byte strings would be automatically coerced into Unicode as needed To convert a text string s into bytes, you must use sencode(encoding) For example, sencode('utf-8') converts s into a UTF-8 encoded byte stringTo convert a byte string t back into text, you must use tdecode(encoding)You can view the encode() and decode() methods as a kind of type cast between strings and bytes Keeping a clean separation between text and bytes is ultimately a good thing the rules for mixing string types in Python 2 were obscure and difficult to understand at best However, one consequence of the Python 3 approach is that byte strings are much more restricted in their ability to actually behave like text Although there are the standard string methods like split() and replace(), other aspects of byte strings are not the same as in Python 2 For instance, if you print a byte string, you simply get its repr() output with quotes such as b'contents' Similarly, none of the string formatting operations (%, format()) work For example:

The loss of text-like behavior with bytes is a potential pitfall for system programmers Despite the invasion of Unicode, there are many cases where one actually does want to

work with and manipulate byte-oriented data such as ASCIIYou might be inclined to use the bytes type to avoid all of the overhead and complexity of Unicode However, this will actually make everything related to byte-oriented text handling more difficult Here is an example that illustrates the potential problems:

Once the interactions and responsibilities of the different classes represented by the CRC cards have been explored, the information can be transferred to a more formal notation such as the UML UML sequence and collaboration diagrams can be developed from the interactions discovered from using the CRC cards UML class diagrams can be derived from the class information contained on a CRC card Associations between classes can be used to build association diagrams However, the main goal of using CRC cards it to gain understanding of the system and how it might work, not to produce UML diagrams Many projects have used CRC cards as their chief documentation process

In the example, you can see how Python 3 is strictly enforcing the text/bytes separation Even operations that seem like they should be simple, such as converting an integer into ASCII characters, are much more complicated with bytes The bottom line is that if you re performing any kind of text-based processing or formatting, you are probably always better off using standard text strings If you need to obtain a byte-string after the completion of such processing, you can use sencode('latin-1') to convert from Unicode The text/bytes distinction is somewhat more subtle when working with various library modules Some libraries work equally well with text or bytes, while some forbid bytes altogether In other cases, the behavior is different depending on what kind of input is received For example, the oslistdir(dirname) function only returns file-

For example, all the bookstore application pages include the file containing the banner content with the following directive:

names that can be successfully decoded as Unicode if dirname is a string If dirname is a byte string, then all filenames are returned as byte strings
