列表、字典和元组值

Question

a=[{"a":30},{"c":("a","=","c")}]

I need values of "c" .

for x in a[1].values():
    for j in x:
        print(j, end=" ")

This is my solution but if you have any other short solution for this then tell me.

Answer 1

You could simply say

for element in a[1]['c']:
       print(element,end=" ")

Answer 2

>>> print(' '.join(*a[1].values())) a = c

Answer 3

如果您只需要打印值，您可以将元组作为参数解包来print ：

print(*a[1]['c'])

Answer 4

The same result can be achieved with a comprehension :

>>> a=[{"a":30},{"c":("a","=","c")}]
>>> print(*(_ for _ in a[1]['c']))
a = c
>>>
