Python中实现，将两个字典变量合并，并且覆盖已有的值，参考代码如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | print 'dict test ++++++++++++++++++'dict1 = {1:111, 2:333}dict2 = {2:22, 4:4444}dict3 = {}dict3 = dict1#for key in dict1:# dict3[key] = dict1[key]for key in dict2.keys(): print key dict3[key] = dict2[key]#dict3 = dict1.update(dict2)print "dict3=",dict3# dict test ++++++++++++++++++# 2# 4# dict3= {1: 111, 2: 22, 4: 4444} |
