Does anyone out there have a simple way to compare two lists (some operator perhaps) and
return
a list of *differences*? By differences, I mean the following: If had two
lists like,
a = [1, 4, 5, 100]
b = [4, 5]
the difference between a and b (a-b) would be [1, 100]. I suppose you could
write a couple of for loops to go through each list and compare them, but I
thought there might be a simple way to do this.
I'm also interested in a simple way to returning a list of what is identical between the
two lists.
In the case of the above lists, a and b, they both contain [4, 5].
If anyone out there has a suggestion (or two) I would very much appreciate it.
Cheers! -Scott
