As you continue to work with the Python language, you will find that often many roads lead to the same destination. The art is in finding which way works better for you. Comprehensions are one of those alternate
. CPython implementation of this rule can be found hereWhen a and b are set to "wtf!" in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf...
Use list comprehensions: List comprehension helps in executing specific operations in both shorter and more basic ways. The performance measures of the code experience better results, which produce both concise and easy-to-read programs. Use virtual environments: It allows managing dependencies separately...
Python functions don't always have a return statement. Generator functions are functions that have the yield keyword instead of return. These functions produce generator iterators, which are objects that represent a stream of data. The elements represented by an iterator are created and yielded only...

7.List Comprehensions: Apart from traditional loops, Python offers list comprehensions, a concise way to create lists. They are often more readable and efficient than using a loop to build a list. squares = [x**2 for x in range(10)] ...
There are cases however, where there is not a single obvious way to do it (unless you're Dutch, of course, as you'll read later in this chapter). That is the goal of this chapter—to learn what code is beautiful and why certain decisions have been made in the Python style guide....
Strings are interned at compile time ('wtf' will be interned but ''.join(['w', 't', 'f']) will not be interned) Strings that are not composed of ASCII letters, digits or underscores, are not interned. This explains why 'wtf!' was not interned due to !. CPython implementation of...
