unfortunately, this module needs to be inside the package, and it also needs to be runnable as a script, sometimes. Any idea how I could achieve that? It’s quite common to have a layout like this… …with a mymodule.py like this… …a myothermodule.py like this… …and a main.py like this… …which works fine when you run main.py or mypackage/mymodule.py, but fails with mypackage/myothermodule.py, due to … Read more
Okay, first things first. There is no such thing as “variable declaration” or “variable initialization” in Python. There is simply what we call “assignment”, but should probably just call “naming”. Assignment means “this name on the left-hand side now refers to the result of evaluating the right-hand side, regardless of what it referred to before … Read more
Starting with Python 3, raw_input() was renamed to input(). From What’s New In Python 3.0, Builtins section second item.
If you know what the Collatz conjecture is, I’m trying to make a calculator for that. I want to have x as my input so I don’t have to change x’s number and save every time I want to try out a new number. I get below error TypeError: not all arguments converted during string … Read more
Every minor version of Python, that is any 3.x and 2.x version, will install side-by-side with other versions on your computer. Only patch versions will upgrade existing installations. So if you want to keep your installed Python 2.7 around, then just let it and install a new version using the installer. If you want to … Read more
Having tested this using Python 3.5 and pip 7.1.2 on Linux, the situation appears to be this: pip install –user somepackage installs to $HOME/.local, and uninstalling it does work using pip uninstall somepackage. This is true whether or not somepackage is also installed system-wide at the same time. If the package is installed at both … Read more
You opened the file in binary mode: This means that all data read from the file is returned as bytes objects, not str. You cannot then use a string in a containment test: You’d have to use a bytes object to test against tmp instead: or open the file as a textfile instead by replacing … Read more
As was stated in the comments to the original post, this seemed to be an issue with the python interpreter I was using for whatever reason, and not something wrong with the python scripts. I switched over from the WinPython bundle to the official python 3.6 from python.org and it worked just fine. thanks for … Read more
FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules. Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A. … When importing the package, Python searches through the directories on sys.path looking … Read more
TL;DR: You can’t do relative imports from the file you execute since __main__ module is not a part of a package. Absolute imports – import something available on sys.path Relative imports – import something relative to the current module, must be a part of a package If you’re running both variants in exactly the same way, one of them should work. Here is … Read more
