The Python Apprentice

Product Information

To get help, simply type help at the prompt: >>> help Type help() for interactive help, or help(object) for help about object. If you have Administrator privileges you should be able to add the paths C:\Python35 and C:\Python35\Scripts to the semicolon separated list of The basic form of importing a module is simply the import keyword followed by a space and the name of the module. For example, lets see how we can use the standard library's math module to compute square roots. At the triple-arrow prompt we type the following command: >>> import math it's easier to get started learning Python by using interesting, engaging examples – something we aim for in this book!

Exploring Built-in Collection Types: We go into more depth on some of the Python collection types, as well as introduce a few more. The great thing about the course is that it is very flexible and can be tailored to meet the needs of each individual and their employer. Within the REPL you can use the special underscore variable to refer to the most recently printed value, this being one of very few obscure shortcuts in Python: >>> _ 15 Within an interactive Python session you can enter fragments of Python programs and see instant results. Let's start with some simple arithmetic: >>> 2 + 2 4 >>> 6 * 7 42

You should now see a progress indicator appear, which will disappear when installation is complete. Not have a higher qualification in the same subject area as the apprenticeship they wish to commence Files and Resource Management: We look at how to work with files in Python, and we cover the tools Python has for Resource Management. There are some exceptions to these rules, but they almost always have to do with improving code readability in other ways, for example by breaking up necessarily long statements over multiple lines.

As you can see, Python reads our input, evaluates it, prints the result, and loops around to do the same again. This simple expression is quite verbose with all those references to the math module. The Python import statement has an alternative form that allows us to bring a specific function from a module into the current namespace by using the from keyword: >>> from math import factorial >>> factorial(n) / (factorial(k) * factorial(n - k)) 10.0 experiments become prototypes and your prototypes become products, Python makes the experience of writing software not just easier but truly enjoyable.Python is a general-purpose programming language. It's not intended for use in any particular domain or environment, but instead can be fruitfully used for a wide variety of tasks. There are, of course, some areas where it's less suitable than others – for example in extremely time-sensitive or memory-constrained environments – but for the most part Python is as flexible and adaptable as many modern programming language, and more so than most.
