I'm converting a bash script to python as it has become rather clumsy
in bash.

However I have hit a problem with converting dates, the bash script
has:-

dat=$(date --date "$1" +"%Y/%m/%d")

and this will accept almost anything reasonably sensible that can be interpreted as a date, in particular it accepts things like "tomorrow", "yesterday" and "next thursday".

Is there anything similar in Python or would I be better off simply
using os.system() to run date from the python program?

in the standard library, datetime

as an addon module, dateutil (install as python-dateutil)

Don't know if either are exactly what you want, but do take a look.

In particular,check out dateutil.parser.
parser — dateutil 2.8.2 documentation <https://dateutil.readthedocs.io/en/stable/parser.html>

parser <https://dateutil.readthedocs.io/en/stable/parser.html#module-dateutil.parser>

This module offers a generic date/time string parser which is able to parse most known formats to represent a date and/or time.

This module attempts to be forgiving with regards to unlikely input
formats, returning a datetime object even for dates which are ambiguous. If
an element of a date/time stamp is omitted, the following rules are applied:

A script I use to create diary entries, so it's very handy to be able
to give the date as 'yesterday' or 'friday'.
