在实际写程序中,经常要对变量类型进行判断,除了用type(变量)这种方法外,还可以用isinstance方法判断:
a = 1 b = [1,2,3,4] c = (1,2,3,4) d = {'a':1, 'b':2, 'c':3} e = "abc" if isinstance(a,int): print ("a is int") else: print ("a is not int") if isinstance(b,list): print ("b is list") else: print ("b is not list") if isinstance(c,tuple): print ("c is tuple") else: print ("c is not tuple") if isinstance(d,dict): print ("d is dict") else: print ("d is not dict") if isinstance(e,str): print ("d is str") else: print ("d is not str")
