字典-基础

# 字典#     字典的索引可以是字符串，除了这一点，它与其它组合类型非常相似。# 当然，字典的索引也可以是整数。dict1 = {}     # 创建一个空的字典dict1['a'] = 1 #增加字典元素print dict1dict2 = {'b':2}print dict2dict3 = {'c':3}print dict3dict4 = {'d':4}print dict4dict5 = {'abc':'cba','def':'fed','port':80}print dict5del dict1['a'] #删除字典元素print dict1dict1.clear()  #清空字典元素 貌似和删除字典元素一样print dict1del dict1      #删除字典对象dict2 = {'g':2}#修改字典对象print dict2
