When zipping with a product iterator with no arguments (which produces only one output, the empty tuple), it seems the check for zip completion does not handle this case:

julia> for (z,) in zip(Iterators.product())
       @show z
       end
z = ()
ERROR: ArgumentError: tuple must be non-empty
Stacktrace:
 [1] first(#unused#::Tuple{})
   @ Base ./tuple.jl:140
 [2] _pisdone
   @ ./ite

See this issue sympy/sympy#11044 . That issue was fixed in PR sympy/sympy#11566. Though no test case was added for the lambdify.

What needs to be done?

Add test case that this works just fine:

>>> from sympy import MatrixSymbol, lambdify
>>> x = MatrixSymbol('x', 3, 1)
>>> f = lambdify(x, x.T*x)

Test case needs to

This little branch adds an interesting "wow" effect by not blanking frames. You can configure a key

Cosmology can now read and write to files.
It would be nice to register with Cosmology.write a method for exporting a Cosmology to a HTML table.
There are good examples of IO with Cosmology at https://github.com/astropy/astropy/tree/main/astropy/cosmology/io
and documentation at https://docs.astropy.org/en/latest/cosmology/io.html#cosmology-io

I'm thinking the write_html(...) method

Version of Singularity:

3.0.3

Expected behavior

Some progress or update information during the creation of the SIF file.

Actual behavior

During "Creating SIF file..." step, the console does not produce any visible output for the user - but does create the resulting file eventually.

Steps to reproduce behavior

I was executing a few “larger” builds through the bui

What is the feature ?

I'm trying out this library for the first time and there's some places where it would be delightful to have shorthand functions:

1. Shorthand functions for Pos: Pos::top_right, Pos::bottom_right, Pos::bottom_center etc..
2. Short way to set colors for components. Currently, lots of boilerplate is required for e.g. white-on-black plotos
   • a cool start would b

could make the chemoreceptor auto select the compound's colour when selecting one, this would make it faster to configure multiple chemoreceptors for different compounds to look for.

Just needs a callback for the option button to detect when it changes value, and then just looking up the compound colour and setting that on the colour picker. Could maybe only change the colour if it is white or
