Beautiful Days at the Movies

    filter and lambda together look too confusing. Generator expressions would be much better here. Also, you don't need absolute value. Mod operation should work on negative numbers. Like this:

    i,j,k = map(int,input().strip().split())
print(sum((x-int(str(x)[::-1]))%k==0 for x in range(i,j+1)))
