We've got a new logo!
Thanks @indeed for sponsoring the creation of the new logo.
And thanks @matplotlib for generating our old logo for more than 10 years (yes, the old logo was generated with a simple Matplotlib script).

We are happy to announce the release candidate of pandas 2.0.0.
It can be installed from our conda-forge and PyPI packages via mamba, conda or pip, for example:

Artificial intelligence may not be so intelligent if it uses pandas .apply() when not strictly necessary.
Our operations are usually vectorized (very fast), .apply() is usually not, so it may be very slow.
Avoid loops and apply if a pandas operation exists for what you need.

We'd like to apologize to @teej_m. This tweet was never meant as a personal attack, or a "fix it yourself" as many users understood.
We welcome all criticism and work with the community every day to make the API better, constrained by being as backward compatible as possible.

#pandas has two internal ways to store strings: NumPy and PyArrow (faster).
pandas 3.0 will change the default and strings will use PyArrow when for example calling read_csv.
You can get this change now in pandas 2.1 with:
pandas.options.future.infer_string = True

This is the (much more efficient) workaround which you're encouraged to use instead - nice one @CaioLCastro !
Use `concat` a single time outside the loop, rather than multiple times inside it
we use a hybrid approach. Append to a list, and then concat.
res = []
for x in itersomething:
res.append(calculations)
pd.concat(res)
df.append is gruesomely inefficient so maybe it is best to remove

New feature alert! ✨
In version 1.5.0 we've added `from_dummies`, which allows you to do decode one-hot-encoded DataFrames

⚠️ Important note for pandas users reading excel files! ⚠️
Please ensure you have the "openpyxl" package installed. Previously, pandas used the "xlrd" package by default. But "xlrd" is only meant to read old xls files, not for .xlsx files.
See warning at pandas.pydata.org/pandas-doc…
xlrd 2.0.1, a #python library for reading .xls files, released. Full details here: groups.google.com/g/python-e…

Bodo has just become a pandas and NumFOCUS financial supporter. Bodo is a just in time compiler that allows executing pandas code in a parallel way without running the pandas underlying code based on NumPy. This should help run pandas code faster and at scale. 1/2

Not easily.
If you for example tell pandas "sum this Series", we do that very fast. If you tell us "run this Python function for each element of the this Series" (what .apply() does), we do that, and that's slow.
