Good point.

Yes, but I'd use it as a replacement for the last test:

# code here ...
elif bank >= 50000 and bank <= 99999:
rate = 0.0149
else:
rate = 0.0173

And finally, I'd simplify the whole damn thing:

if bank < 1:
print("You're in the red!")
quit()
elif bank < 10000:
rate = 0.0060
elif bank < 25000:
rate = 0.0085
elif bank < 50000:
rate = 0.0124
elif bank < 100000:
rate = 0.0149
else:
rate = 0.0173

It couldn't, indeed. Which FWIW is a clear indication that the previous
test ( elif bank >= 100000:) is redundant !-)
