Is it possible to get two nested for statements followed by a nested if/else statement all into a single list comprehension ie. the equivalent of the below:
for i in xrange(1,20): for j in xrange(1,10): if j<6: j=int("8"+str(j)) else: j=int("9"+str(j)) print "%(i)02d_%(j)02d" % locals() # double for statement without if/else works print "\n".join(["%(i)02d_%(j)02d" % locals() for i in xrange(1,20) for j in xrange(1,10)]) #now try to incorporate if/else part #failed attempt 1 print "\n".join(["%(i)02d_%(j)02d" % locals() for i in xrange(1,20) for j in xrange(1,10) j=int("8"+str(j)) if j<6 else int("9"+str(j))]) #failed attempt 2 print "\n".join(["%(i)02d_%(j)02d" % locals() for i in xrange(1,20) j=int("8"+str(j)) if j<6 else int("9"+str(j)) for j in xrange(1,10)]) #failed attempt 3 print "\n".join(["%(i)02d_%(j)02d" % locals() j=int("8"+str(j)) if j<6 else int("9"+str(j)) for i in xrange(1,20) for j in xrange(1,10)]) Many thanks in advance.
