The next step is to learn its idioms, or Python-specific coding practices. Certain Python language features lend themselves to writing code in ways that have become known as pythonic. In this chapter, I’ll provide several common ways of writing idiomatic Python code along with their unpythonic...

= fresh_fruit.get'lemon', 0) if count: make_lemonade(count) else: out_of_stock() 加入表达式后,你可以使上面的代码更清晰: ifcount := fresh_fruit.get'lemon', 0): make_lemonade(count) else: out_of_stock() 显然由于Python的赋值语句不存在返回值,因此像是a = b = c这种代码确实是...
Most of us have some go-to functions when we code. Once we are used to coding in a certain way, we tend to use the same functions over and over again, even when there may be a much better way. And…
It allows a (near) line-into-line rewrite of a Python code into Java. It's also a great way to prototype your algorithms directly in Java.xpresso implements in Java familiar pythonic methods (e.g., len, enumerate, split/join, slicing) and coding paradigms (e.g., everything is ...

Say you’re coding an application to manage your clients’ information. The application uses a database to store clients’ data. To process the data and update the database, you’ve created several functions. One of your high-level functions is create_user(), which looks like this: Python...
