python字典，其值具有多个参数

Question

i have a problem in fetching values from a dictionary. di is a dictionary.

for key in di.keys()
    print("key is = %s" %key)
for value in di.values()
    print("value is = %s" %value)

it gives output as

key is = 1

and

value is = xyz=0 | pqr=70 | abc=300

i want all 3 values(0,70,300) above in separate variables. i am not able to do

di['xyz']

since xyz is itself in a value. how to fetch all these values? is it a nested dictionary?

Answer 1

From the looks of it, this is your dictionary

>>> di = {'1': 'xyz=0 | pqr=70 | abc=300'}

Or maybe {1: 'xyz=0 | pqr=70 | abc=300'} {1: 'xyz=0 | pqr=70 | abc=300'} {1: 'xyz=0 | pqr=70 | abc=300'} , but you weren't very clear in the question so I'll assume the first.

It's weird that you would have this as a dictionary, so I won't bother trying to think about why that may be, instead I'll just show you how you could build what you want from the string 'xyz=0 | pqr=70 | abc=300' 'xyz=0 | pqr=70 | abc=300'

>>> di['1'].split(' | ')
['xyz=0', 'pqr=70', 'abc=300']

Splits by the vertical bars

>>> [x.split('=') for x in di['1'].split(' | ')]
[['xyz', '0'], ['pqr', '70'], ['abc', '300']]

Splits by equal signs to make key-pair lists

>>> dict(x.split('=') for x in di['1'].split(' | '))
{'xyz': '0', 'abc': '300', 'pqr': '70'}

Builds a dict out of that

>>> di = dict(x.split('=') for x in di['1'].split(' | '))
>>> di['xyz']
'0'

and now you can access it like di['xyz']
