i code using a german layout and to type any kind of bracket you have to use a modifier key and a number. its awkward, but i am to lazy to switch between layouts and sometimes work on machines where i can't change the layout easily.

python is quite nice to programm on a german layout, because it tends to have fewer braces than other languages.

tl;dr: german keyboard layout "hides" many symbols on a second layer beneath the number row which makes it awkward to use for many programming languages.
