Python 2.3 (59 encodings) Apparently, the following is the valid syntax: I found a related question right here on SO, but that question is about PHP though, and it states the b is used to indicate the string is binary, as opposed to Unicode, which was needed for code to be compatible from version of PHP < 6, when migrating to PHP 6. I think you have to consider various time factors here. You will learn Python fundamentals, including data structures and data analysis, complete hands-on exercises throughout the course modules, and create a final project to demonstrate your new skills.

Make a wide rectangle out of T-Pipes without loops. RevealerTransitionType: These enumeration values describe the possible transitions when the child of a GtkRevealer widget is shown or hidden. Maybe you should try using the Universal Encoding Detector (chardet) library instead of implementing it yourself. It doesn't explain the question that Jesse Webb has asked! literal should become a bytes literal So yes, b'' literals in Python have the same purpose that they do in PHP. The b'' notation is somewhat confusing in that it allows the bytes 0x01-0x7F to be specified with ASCII characters instead of hex numbers.
