我想把"复杂"打印出来,但什么都没有发生,为什么?如何正确处理?
1 2 3 4 5 6 | >>> c = (5+3j) >>> type(c) <type 'complex'> >>> if type(c) == 'complex': print 'complex' ... >>> |
您可以使用
1 | if isinstance(c, complex): |
从文档中:
Return true if the object argument is an instance of the classinfo argument, or of a (direct, indirect or virtual) subclass thereof. Also return true if classinfo is a type object (new-style class) and object is an object of that type or of a (direct, indirect or virtual) subclass thereof.
1 2 3 4 5 6 7 8 9 10 11 12 | >>> c = 5+3j >>> c (5+3j) >>> type(c) <type 'complex'> >>> complex <type 'complex'> >>> type(c) == complex True >>> isinstance(c, complex) True >>> |
