Treading on Python: Volume 2 Intermediate Python
Treading on Python: Volume 2 Intermediate Python
Functional Python, Decorators, Generators, and more
About the Book
Write Python code like the masters
These constructs, while not necessary per se, allow you to be more succinct, re-use code, and think about code in a different way. You will learn:
-
how the constructs work
-
when to use them
-
real like examples from the standard library
Understand other's code
This book covers many of these intermediate constructs that are available in Python. The book covers both Python 2 and 3. Topics include:
-
Functional programming
-
List comprehensions
-
Generator expressions
-
Set & dict comprehensions
-
Iteration
-
Generators
-
Closures
-
Decorators
