Sadly, I don't know enough German to understand what is
going on, but given the original basic: 

      140 CLS : RANDOMIZE TIMER: PRINT
      150 PRINT "Von 2000 Wechseln waren ": PRINT
      160 FOR i = 1 TO 10
      170 r = 0: f = 0
      180 FOR j = 1 TO 2000
      190 a = INT(3 * RND + 1)
      200 w1 = INT(3 * RND + 1)
      210 m = INT(3 * RND + 1)
      220 IF (m = a) OR (m = w1) THEN 210
      230 w2 = 6 - m - w1
      240 IF w2 = a THEN r = r + 1
      250 IF w1 = a THEN f = f + 1
      260 NEXT j
      270 PRINT "richtig:"; r; "falsch:"; f
      280 NEXT i
      290 END

This is the most literal Python translation I could write:

import random

def rnd():
   ' returns one of (1,2,3) at random. '
   return int(3*random.random() + 1)

print "\nVon 2000 Wechseln waren \n"
for i in range(1,11):
    r = 0; f = 0
    for j in xrange(1,2001):
       a = rnd()
       w1 = rnd()
       m = rnd() 
       while m in (a, w1): 
          m = rnd()
       w2 = 6 - m - w1
       if w2 == a: r += 1
       if w1 == a: f += 1
    print "richtig: %s falsch: %s" % (r,f) 


I'm-guessing-the-last-pair-is-true-or-false-but-darned-if-I-know-
   what's-going-on-ly yrs,
