As you split a Python project into packages, you may see a leading dot in an import and wonder which module it names. Python relative imports use those dots to resolve a name from the importing module’s package. I’ll explain…
Calendar-based tasks often need every day between a start date and an end date. Python’s date and timedelta classes let you move forward one day at a time to build that sequence. I’ll show how to create a range that…
Pip’s `error: failed-wheel-build-for-install` summary can appear without explaining what went wrong. I wanted to separate the failed stage from the cause behind it. Read the build output for the package name. You can compare it with the earlier error to…
A matrix of feature rows can produce one output from `np.linalg.norm(matrix)`, even when the next step needs a length for each row. I was curious that `axis=1` can preserve that row-by-row view without changing the matrix. A norm reports size…
I had three points and a line to fit, and I kept writing normal equations by hand. I expected residuals to always be a number, so the empty array on my first exact system felt like a bug until I…
I hit the Python int wall on a 10,000-digit number and got a ValueError I did not expect. I had assumed unlimited meant no limits anywhere, which felt safe until str() refused to convert the value. Once I traced the…
Python prints very small floats in scientific notation, like 1e-05 instead of 0.00001. The decimal form comes back with the right format specifier, in your output and in the files you write. Where the exponent form comes from Python stores…
![[SOLVED] ‘Unexpected Keyword Argument’ TypeError in Python](https://www.askpython.com/wp-content/uploads/2026/09/unexpected-keyword-argument-typeerror-featured-768x432.png)
Python raises a TypeError when a function call passes a keyword argument the function’s signature does not accept. The traceback names the offending argument so you can fix the call site, the function definition, or both. An unexpected keyword argument…
I ran into a confusing error the first time I tried to install the Levenshtein package on Windows. The pip install failed with a cryptic message about missing build tools, and I had no idea where to start. That confusion…
I keep coming back to simple file-based projects when I want to teach someone how Python actually works. There’s something about reading and writing data that makes the language feel real rather than abstract. The golf scores program is one…
