Python字典转换为小写？

Question

我有这个需要转换为小写的Python字典.字典由需要对不区分大小写输入的数据组成,例如,它适用于resp ='GBR'或'gbr'.希望我在这里有意义.任何帮助将非常感谢!

resp = raw_input('Which country is ' + record['name'] + ' in? ')
        print " "
        valid = {'GBR': ['GBR',
                        'United Kingdom',
                        'UK',
                        'Great Britain and Northern Island',
                        'GB'
                        ],
                'IRL': ['IRL',
                        'Eire',
                        'Republic of Ireland'
                        ]
            }
        if resp in valid[record['sov']]:
            answ = 'Yes, ' + record['name'] + ' is in the ' + resp

Answer 1

如果它需要对应不区分大小写的输入,我建议.lower()您在输入和字典值之间进行比较时添加一个调用,而不是仅为此创建/转换第二个字典.

但是,鉴于你的字典已经是大写的,我会用.upper()你的输入大写来转换你的字典,而不是反过来做
