小編給大家分享一下python中遍歷字典的方法,相信大部分人都還不怎么了解,因此分享這篇文章給大家學(xué)習(xí),希望大家閱讀完這篇文章后大所收獲,下面讓我們一起去學(xué)習(xí)方法吧!
1. 遍歷字典的鍵key
python學(xué)習(xí)網(wǎng),大量的免費(fèi)python視頻教程,歡迎在線學(xué)習(xí)!
①
>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for key in d: print(str(key)+':'+str(d[key])) list:[1, 2, 3] 1:123 111:python3 tuple:(4, 5, 6)
②
>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for key in d.keys(): print(key) 1 list 111 tuple
2. 遍歷字典的值value
>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for value in d.values(): print (value) [1, 2, 3] 123 python3 (4, 5, 6)
3. 遍歷字典的項(xiàng)
>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for item in d.items(): print(item) ('list', [1, 2, 3]) (1, 123) ('111', 'python3') ('tuple', (4, 5, 6))
4. 遍歷字典的key-value
①
>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for key,value in d.items(): print(key,value) list [1, 2, 3] 1 123 111 python3 tuple (4, 5, 6)
②
>>> d={'list':[1, 2, 3],1:123,'111':'python3','tuple':(4, 5, 6)} >>> for (key,value) in d.items(): print(key,value) list [1, 2, 3] 1 123 111 python3 tuple (4, 5, 6)
