For anyone curious, here's a comparison (that I wrote a couple days ago) of FizzBuzz in K vs. q vs. python... please note the insane syntax for K4 (which is a proprietary language of KX Systems and is thus undocumented).

K

    \c 150 100 
    c:{$[0=x-5*x div 5;$[0=x-3*x div 3;"CracklePop";"Pop"];$[0=x-3*x div 3;"Crackle";x]]}'1_!101 
    r:{x@&~x in "\""} 
    p:{-1 r .Q.s x}
    p c 
    \\

q (the "readable" wrapper around K4")

    \c 150 100
    c:{$[0=x mod 5;$[0=x mod 3;"CracklePop";"Pop"];$[0=x mod 3;"Crackle";x]]} each 1_til 101 -1 ssr[.Q.s c;"\"";""] 
    \\

Here’s a python (2.7) version of the program written in as unreadable as I could muster

    for i in map(lambda x: "CracklePop" if not x % 3 and not x % 5 else "Crackle" if not x % 3 else "Pop" if not x % 5 else x, xrange(1,101)): print i

Here it is in normal python (2.7)

    for x in xrange(1,101):
        if not x % 5: 
            if not x % 3: 
                print "CracklePop" 
            else: 
                print "Pop" 
        elif not x % 3: 
            print "Crackle" 
        else: 
            print x
