Jun 22, 2016 · As mentioned in the comments, from is a Python keyword so you can't use it as a variable name, or an attribute name. So you need to use an alternative name, and do a conversion when reading or writing the JSON data.
A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for Python variables: A variable name must start with a letter or the underscore character. A variable name cannot start with a number.
Effective variable naming enhances code readability and maintainability. This post dives deep into the rules, conventions, and best practices for naming variables in Python, offering examples and tips to avoid common pitfalls.
Function names should be lowercase, with words separated by underscores as necessary to improve readability. Variable names follow the same convention as function names. mixedCase is allowed only in contexts where that's already the prevailing style (e.g. threading.py), to retain backwards compatibility.

Python naming conventions are a set of guidelines established in PEP8, Python’s official style guide. These guidelines set the standard for how we name variables, functions, classes, modules, and other identifiers. While these conventions are not enforced by the Python interpreter, adhering to them is considered a mark of good coding practice. They...
The most fundamental rules in Python’s naming conventions are: 1. Names are case-sensitive. 2. Names cannot start with a digit. 3. Names can contain letters, numbers, and underscores.
There are several styles used in Python: 1. Snake Case: Snake case has all words lowercase separated by underscores. This is primarily used for function and variable names. Example: user_name, my_function 1. Pascal Case: Pascal case is similar to camel case but starts with a capital letter. This is used for class names in Python. Example: ClassName...
In Python, a variable declared outside of a function or a block of code is referred to as a global variable. These global variables can be accessed by any function in the program. When it comes to naming global variables in Python, the PEP8 style guide provides clear guidelines. As a convention, global variables should be named following the snake_...
In Python, the naming convention for classes is PascalCase, which means that the first letter of each word is capitalized and there are no underscores between words. Here’s an example:
Objects in Python are instances of a class that you’ve defined. The naming convention for Python objects follows the same rules as that for regular variables. When you create an object, the name should be in snake_case, which means all words are in lowercase, and words are separated by underscores. The name should be descriptive, making it clear wh...
In Python, variable names follow the snake_case naming convention as per the PEP8 style guide. This means that all words in the name are in lowercase, and each word is separated by an underscore. Here’s an example: Here are a few more guidelines when naming variables in Python: 1. Variable names should be descriptive and meaningful to make the code...
In Python, function names follow the snake_case naming convention as per the PEP8 style guide. This means all words should be in lowercase, and each word is separated by an underscore. Here’s an example: Here are a few more guidelines when naming functions in Python: 1. Descriptive Names: Function names should be descriptive and indicate the functi...
Adhering to Python’s naming conventions is a crucial aspect of writing clean, professional, and efficient code. It makes your code much more readable and understandable, not just to others, but to your future self as well. Python’s naming conventions, outlined in the PEP8 style guide, provide clear directions for how identifiers such as variables, ...
We cannot use a keyword as a variable name, function name, or any other identifier. They are used to define the syntax and structure of the Python language. All the keywords except True , False and None are in lowercase and they must be written as they are.

Three Python keywords are used to work with variables. The del keyword is much more commonly used than the global and nonlocal keywords. But it’s still helpful to know and understand all three keywords so you can identify when and how to use them. The del Keyword. del is used in Python to unset a variable or name.
