This article mainly explains "beginners how to better self-study Python code", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "beginners how to better self-study Python code" bar!

1. List, Dictionary and set understanding

List understanding is one of the most emphasized features of many Python software engineers, which is a very short way to make iterative objects iterable. The basic punctuation mark is [iterable x expression].

In addition to list awareness, there are other word references and set understandings. Word reference awareness has an accompanying basic language structure {key_expr: value_expr} for iterable of x, while for set understanding, the basic structure is {expression inerable} for x.

two。 Name the tuple a data structure

Named tuple information types can be very useful lightweight information structures, and namedtuple information types can be accessed through the classification module using the following basic punctuation marks: namedtuple (Typename,field_names).

3. Iterate with enumerate () and zip ()

A key rule in coding is DRY, which means don't repeat yourself. This is a typical assignment when we use a set of information (such as a number summary) to work, and we have to do a similar activity for each number in the summary. To avoid redistributing similar code, we can use the for loop to run the entire failed loop.

When we repeat a reduction or any grouping, we also need to know how things are continuous, and there are several different ways to do this. In addition to the identify () function, the zip () function is also valuable in terms of emphasis, which enables many iterable objects to form tuples without explicitly making composite iterable objects possible.

4. Format a string with an f string

Introducing the f string as the string literal, using the letter f (or F) as the prefix for the string literal f string is not using the join () technique with images and strings, but is very clearly used for string linking.
