if __name__ == "__main__":

    if len(sys.argv) < 2:

        print(f"Warning: No matching data found in '{input_filepath}'.", file=sys.stderr)

Math

You can use LaTeX math in your posts. For inline math, use single dollar signs, e.g. $E = mc^2$.

For display math, use double dollar signs:

$$ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$

You can also use environments like align:

$$ \begin{align} a^2 + b^2 &= c^2 \
\nabla \cdot \vec{E} &= \frac{\rho}{\varepsilon_0} \end{align} $$

Here is a very long LaTeX equation to test horizontal scrolling and container overflow:

$$ \int_{-\infty}^{\infty} \frac{1}{\sqrt{2\pi\sigma^2}} e^{-\frac{(x-\mu)^2}{2\sigma^2}} dx = 1 \quad \text{where} \quad \mu \text{ is the mean and } \sigma^2 \text{ is the variance of the normal distribution function, and this equation is intentionally long to test the rendering and scrolling behavior of MathJax in Hugo posts.} $$
