+1 one this. And a list.get method has well, with a default value.

Sorry in advance if this has been proposed in the past but I couldn't find anything on python-ideas: >>> l = [] >>> l.pop(default=1) 1 FWIW my use case consists in reading entries from /proc/diskstats where lines can have a variable number of fields depending on the kernel version: https://github.com/giampaolo/psutil/issues/1354#issuecomment-434495870 https://github.com/giampaolo/psutil/blob/d8b05151e65f9348aff9b58da977abd8cacb2127/psutil/_pslinux.py#L1068 As such it would be convenient to set missing fields to 0 as "reads = fields.pop(default=0)" instead of catching IndexError every time. Extra: for consistency set.pop() should probably have the same.
