dict = {}
dict['one'] = "This is one"
dict[2] = "This is two"
tinydict = {'name': 'john','code':6734, 'dept': 'sales'}
print dict['one'] # 输出键为'one' 的值
print dict[2] # 输出键为 2 的值
print tinydict # 输出完整的字典
print tinydict.keys() # 输出所有键
print tinydict.values() # 输出所有值
输出结果为：
This is one This is two {'dept': 'sales', 'code': 6734, 'name': 'john'} ['dept', 'code', 'name'] ['sales', 6734, 'john']
Python成员运算符
除了以上的一些运算符之外，Python还支持成员运算符，测试实例中包含了一系列的成员，包括字符串，列表或元组。
以下实例演示了Python所有成员运算符的操作：
#!/usr/bin/python a = 10 b = 20 list = [1, 2, 3, 4, 5 ]; if ( a in list ): print "Line 1 - a is available in the given list" else: print "Line 1 - a is not available in the given list" if ( b not in list ): print "Line 2 - b is not available in the given list" else: print "Line 2 - b is available in the given list" a = 2 if ( a in list ): print "Line 3 - a is available in the given list" else: print "Line 3 - a is not available in the given list"
以上实例输出结果：
Line 1 - a is not available in the given list Line 2 - b is not available in the given list Line 3 - a is available in the given list下载本文
