Syntax question

[pmz]

Dear Group,

It's really rookie question, but I'm currently helping my wife in some
python-cases, where I'm non-python developer and some of syntax-diffs
make me a bit confused.

Could anyone give some light on line, as following:
"ds = d[:]"  ### where 'd' is an array

Let me guess, is it a declaration of two-dimension array?

Thanks a lot for help and all the best,
