^ Python Questions
Question: what is the syntax or python-ism in this construct?:
if __name__ == '__main__':
main()
Question: what is method chaining in Python?
Question: what is the difference between a Python library and a Python module?
^ Python Data Types
The following Python3 online documentation page mentions early on how Python distinguishes Unicode strings and 8-bit strings which it also calls 'bytes'. This may be a starting point to understanding how and when Python3 treats data as bytes:
^ Python Libraries
Starting point to describe Python language libraries and cases where they are needed:
- https://docs.python.org/3/library/os.html . . . os library - "Miscellaneous operating system interfaces"
- https://docs.python.org/3/library/sys.html . . . sys library
- https://docs.python.org/3/library/zlib.html . . . zlib library
^ Docstrings
Python document strings or "docstring" instances are an important feature of Python. As a newcomer to Python docstrings sound like a way to document Python functions and modules. Looks like they also provide a way to check return types for correctness or matching to a particular type, and further checks of parameters.
^ Python Modules
Python scripting language includes a module called `subprocess`. Sounds like this module is akin to C library's `exec()` family functions, at least in the functionality it provides. Starting notes on Python subprocess here:
^ Strings and Long Lines
To express long lines in Python there are a couple of methods. The `textwrap` library or module contains some utils to help with this. To use parentheses about a multi-line string also provides a way.
