The code of yours gets a commaseparated _string_, which you are
putting into a list. The list contains one element only; the string
you entered.

What you want to do is this:

print "Input list separated by commas"
foo = raw_input()
lst = foo.split(",")
print lst
print len(lst)
print lst

raw_input() is not smart enough to split the elements for you, so you
need to do the dirty work. The string-method "split" does this. Type
help("".split) for more info.
