The Python Apprentice

By: Robert Smallshire, Austin Bingham

Overview of this book

Experienced programmers want to know how to enhance their craft and we want to help them start as apprentices with Python. We know that before mastering Python you need to learn the culture and the tools to become a productive member of any Python project. Our goal with this book is to give you a practical and thorough introduction to Python programming, providing you with the insight and technical craftsmanship you need to be a productive member of any Python project. Python is a big language, and it’s not our intention with this book to cover everything there is to know. We just want to make sure that you, as the developer, know the tools, basic idioms and of course the ins and outs of the language, the standard library and other modules to be able to jump into most projects.

Strings in action


We covered the str type at some length already in chapter two, but we'll take time now to explore its capabilities in a more depth.

The length of a string

As with any other Python sequence, we can determine the length of a string with the built-in len() function.

>>> len("llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch")
58

The sign for the railway station at Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogo gogoch on the Welsh island of Anglesey – the longest place name in Europe:

Figure 5.1: The longest place name in Europe

Concatenating strings

Concatenation of strings is supported using the plus operator:

>>> "New" + "found" + "land"
Newfoundland

Also the related augmented assignment operator:

>>> s = "New"
>>> s += "found"
>>> s += "land"
>>> s
'Newfoundland'

Newfoundland, the sixteenth largest island in the world, is one of relative few closed, triple-compound words in English:
