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

This is one

This is two

{'dept': 'sales', 'code': 6734, 'name': 'john'}

['dept', 'code', 'name']

['sales', 6734, 'john']
