使用通配符搜索字典键值

Question

There is any way to use a wildcard in order to skip a dictionary key. I have the following nested dictionary:

{'1': {'date': '25-Jan-21 12:45:15:788 ', 'payload':' ****AAAA** **\n****'}, 
'2': {'date': '25-Jan-21 12:45:15:881 ', 'payload': ****'BBB**\n\n**'}, 
'3': {'date': '25-Jan-21 12:45:15:897 ', 'payload': ' ****CCC**\n**'}, 
'4': {'date': '25-Jan-21 12:45:15:907 ', 'payload': ' ****DDD** \n**'}}

And i want to ignore the first keys 1, 2.... and extract only the value corresponding to payload key.

is possible to use some kind of wild card like i tried below?

for i in data['*']['payload']:
    print(i)

Answer 1

simply iterate over it

for k1 in d:
    for k2 in d[k1]:
        payload = d[k1][k2]
        print(k2,'>>', payload)

output

date >> 25-Jan-21 12:45:15:788 
payload >> ****AAAA** **
****
date >> 25-Jan-21 12:45:15:881
payload >> ****BBB**

**
date >> 25-Jan-21 12:45:15:897
payload >> ****CCC**
**
date >> 25-Jan-21 12:45:15:907
payload >> ****DDD** 
**

Answer 2

d = {'1': {'date': '25-Jan-21 12:45:15:788 ', 'payload':' ****AAAA** **\n****'}, 
'2': {'date': '25-Jan-21 12:45:15:881 ', 'payload': ' ****BBB**\n\n**'}, 
'3': {'date': '25-Jan-21 12:45:15:897 ', 'payload': ' ****CCC**\n**'}, 
'4': {'date': '25-Jan-21 12:45:15:907 ', 'payload': ' ****DDD** \n**'}}

for el in d.values():
    print(el['payload'])

Or:

print([el['payload'] for el in d.values()])

You can iterate over the values in the directory using .values() . From there, you can access payload rather easily.

Answer 3

To ignore the first two values of a list you would tipically do lst[2:] , but data.values() isn't a list, so we need to turn it into one using list(data.values()) :

for value in list(data.values())[2:]:
    print(value['payload'])

(The same can be done with data.items() if you need access to the key)
Output:

 ****CCC**
**
 ****DDD** 
**
