Head First Python, Barry P., 2017.

   Want to learn the Python language without slogging your way through howto manuals? With Head First Python, you’ll quickly grasp Python’s fundamentals, working with the built-in data structures and functions. Then you’ll move on to building your very own webapp, exploring database management, exception handling, and data wrangling. If you’re intrigued by what you can do with context managers, decorators, comprehensions, and generators, it’s all here. This second edition is a complete learning experience that will help you become a Python programmer in no time.




Indentation takes time to get used to.
Don’t worry. Everyone coming to Python from a “curly-braced language” struggles with indentation at first. But it does get better. Alter a day or two of working with Python, you’ll hardly notice you’re indenting your suites.

One problem that some programmers do have with indentation occurs when they mix tabs with spaces. Due to the way the interpreter counts whitespace, this can lead to problems, in that the code “looks fine” but refuses to run. This is frustrating when you're starting out with Python.

Our advice: don’t mix tabs with spaces in your Python code.
In fact, we’d go even further and advise you to configure your editor to replace a tap of the Tab key with four spaces (and while you’re at it, automatically remove any trailing whitespace, too). This is the well-established convention among many Python programmers, and you should follow it, too. We’ll have more to say about dealing with indentation at the end of this chapter.
