Does Python Use Camel Case?
Direct Answer:
No, Python does not use camel case. Instead, it uses underscore notation for separating words in variable names, function names, and module names. This is in contrast to other programming languages like Java and JavaScript, which use camel case to follow the conventions of the language.
History of Python’s Naming Conventions
Before diving into the reasons behind Python’s choice, let’s take a brief look at its evolution. Python’s creator, Guido van Rossum, developed the language in the late 1980s. At that time, many programming languages, including Pascal, C, and Perl, used underscored notation for variable names and identifiers. This convention was carried over to Python, which was designed to be easy to learn and use, with a focus on readability and simplicity.
Advantages of Underscored Notation
Here are some significant advantages of using underscored notation in Python:
- Readability: Variables and identifiers become more readable with clear separation between words, making it easier for developers to understand the code.
- Avoids Casing Confusion: With underscored notation, there’s no need to worry about case sensitivity, which can lead to errors and bugs.
- Less Typing: Underlined notation requires less typing, making it a more efficient option for developers.
Table: Comparison of Naming Conventions
| Language | Naming Convention | Example |
|---|---|---|
| Python | Underscored (hello_world) | hello_world |
| Java | Camel case (helloWorld) | helloWorld |
| JavaScript | Camel case (helloWorld) | helloWorld |
Arguments Against Camel Case
H3: Consistency and Brevity
While some may argue that camel case is more concise, underscored notation achieves the same brevity without sacrificing readability. In Python, it’s common to use meaningful variable names, which can often be shorter than their camel case counterparts. For example, sum_of_numbers is more descriptive and readable than sumOfNumbers.
H3: Aesthetics
Another argument against camel case is that it can lead to aesthetics issues. While it’s true that camel case can be visually appealing in some languages, it can also make code difficult to read, especially when using long variable names. Underscored notation, on the other hand, provides a clear visual separation between words, making the code more readable.
Conclusion
In conclusion, Python does not use camel case. Instead, it relies on underscored notation for separating words in variable names, function names, and module names. This convention has several advantages, including improved readability, reduced casing confusion, and less typing. With its focus on simplicity and readability, Python’s use of underscored notation is a testament to its design philosophy.
