仅打印奇数字典键及其项

Question

我有以下字典，我只需要打印带有奇数（1、3 ...）的字典。我将如何去做？

zen = {
    1: 'Beautiful is better than ugly.',
    2: 'Explicit is better than implicit.',
    3: 'Simple is better than complex.',
    4: 'Complex is better than complicated.',
    5: 'Flat is better than nested.',
    6: 'Sparse is better than dense.',
    7: 'Readability counts.',
    8: 'Special cases aren't special enough to the rules.',
    9: 'Although practicality beats purity.',
   10: 'Errors should never pass silently.'
   }

到目前为止，我有：

for c in zen:
print (c , zen[c][:])

Answer 1

如果您的密钥是数字：

for i in range(1,len(zen),2):
    print(zen[i])

它从1开始，然后以2为步长，所以我只会赔率

另一个较短的方法是列表理解，但是这有点不寻常，因为您实际上不需要列表。

[print(zen[i]) for i in zen if i%2==1]
