do you see CamelCase much in Python methods and functions?

Question

The PEP 8 style guide (Python) says methodnames should be lowercase and that sometimes method_names may have embedded underscores. Do experienced Python programmers often come across CamelCase (with leading capital) methods?

Answer 1

In my experience, a module's naming conventions depends on the following factors:

• If it's a newly written, Python-only module, or if the authors especially care for "Pythonic code" (quite common!), the naming usually sticks to the recommendations in the Python Style Guide.
• Beginners to Python often stick to their favorite style, especially if they have a Java/C#/... background.
• Some companies prefer a consistent naming style across languages.
• Some Python modules adapt an API from other languages (especially Java in the threading and xml.dom modules), including naming style.
• Python bindings for C/C++ libraries usually keep the original naming (e.g. camelCase for PyQt or PascalCase for VTK)

I think the last point is the most common way that you will find PascalCase in Python code.
