Loops and control structures

Using logical control structures for loops is also part of good programming style.

It helps someone reading the code understand the execution sequence (in imperative programming).

For example, the following pseudocode:

The above excerpt complies with both of the above style recommendations, but the following use of the for construction makes the code much easier to read:.

In many languages, the frequently used pattern "for each element in a range" can be shortened to:.

Spacing

Free-form languages often ignore whitespace.

Good use of spacing in the layout of one's code is therefore considered good programming style.

Compare the following extract of C code:.

with:.

In programming languages ​​of the C family it is also recommended to avoid using tab characters in the middle of a line, since different text editors display their width differently.

The Python programming language uses indentation to indicate control structures, therefore good indentation is required.

By doing this, the need to mark with curly braces ({ and }) is eliminated, and readability is improved without interfering with common coding styles.

However, this frequently leads to problems where code is copied and pasted into a Python program, requiring tedious reformatting. Additionally, Python code becomes unusable when it is posted on a "Forum (Internet)") or web page that removes white space.
