print "This is a program for room." print "How long is the room's width?", a = int(raw_input()) print "How long is the room's height?", b = int(raw_input()) M = a * b print "The whole room needs", M, "ditan."
这个没问题。
但看书里可以把提示语写进raw_input里,所以写了第二个:
print "This is a program for ditan." a = raw_input("How long is the room's width?"), b = int(a) c = raw_input("How long is the room's height?"), d = int(c) m = b*d print "The whole room needs", m, "ditan."
提示 int() argument must be a string or a number, not 'tuple'
