How to solve the non-standard function name error in Python code?

During the programming process of Python, sometimes errors with non-standard function names are found, which will bring great difficulties to the maintenance and reading of the program. This article will describe how to solve this problem, including naming conventions and code refactoring.

1. Naming rules

In Python, there are some naming rules that can help developers write more standardized code. We can follow these rules and use a unified naming method to improve the readability and maintainability of the code.

• Function names should be clear and descriptive
  Function names should be simple and clear, using one or more words to describe the function of the function, and abbreviations should be avoided as much as possible. For example, a function that calculates the sum of two numbers should be named add, not a or ad.
• Function names must conform to camel case nomenclature
  In Python, camel case nomenclature is usually used to define function names. That is, the first letter of the function is lowercase, and the first letter of the following words is capitalized. For example, a function that calculates the average of two numbers should be named calculateAverage.
• It is not recommended to use an underscore to start a name
  In Python, a function name starting with a single underscore indicates that the function is a private function. In general, avoid using such function names unless they are really only used inside the class.
• Name should express the intention
  The function name should be able to express the intention of the function. For example, a function that reads data from the database should be named: get_data_from_database().

2. Code Refactoring

If you have written the code but find that the function name is not standardized, you can choose to refactor the code. Refactoring is the process of rewriting or restructuring code to improve its quality and readability while keeping its functionality intact.

• Rename function
  For existing functions, you can rename the function and modify it according to the above naming rules. Make sure the new name more clearly describes the function's functionality, making the code easier to read and reducing the chance of errors.
• Split function
  If the function of a function is too complex, consider splitting it into multiple simple functions. Each function has its own functionality and is reusable.
• Encapsulation function
  The longer a function is, the more difficult it is to maintain. Therefore, encapsulating a piece of code in a function can make the code clearer, easier to maintain and reuse.

Summary

Reasonable naming conventions and reasonable code refactoring can improve code readability and maintainability, thereby improving code quality and efficiency. For those non-standard function names, we can use the above method to improve them and get better code.
