is there any possible way to exctract the number from dictionary by only using regex [closed]

{"orders": [{"id":1},{"id":2},{"id":3},{"id":4},{"id":5},{"id":6},
            {"id":7},{"id":8},{"id":9},{"id":10},{"id":11},{"id":648},
            {"id":649},{"id":650},{"id":651},{"id":652},{"id":653}
            ]
 }

need to extract only numbers by using regex in python

I try to address the numbers but I can’t i just want the number in the list

Answer

A regex isn’t appropriate here, but you can get all the id numbers with a simple list comprehension:

>>> d = {"orders":[{"id":1},{"id":2},{"id":3},{"id":4},{"id":5},{"id":6},{"id":7},{"id":8},{"id":9},{"id":10},{"id":11},{"id":648},{"id":649},{"id":650},{"id":651},{"id":652},{"id":653}]}
>>> [o["id"] for o in d["orders"]]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 648, 649, 650, 651, 652, 653]

If what you have is a string, luckily it’s valid JSON, so use json.loads to turn it into a dictionary:

>>> j = '''{"orders": [{"id":1},{"id":2},{"id":3},{"id":4},{"id":5},{"id":6},
...             {"id":7},{"id":8},{"id":9},{"id":10},{"id":11},{"id":648},
...             {"id":649},{"id":650},{"id":651},{"id":652},{"id":653}
...             ]
...  }'''
>>> import json
>>> [o["id"] for o in json.loads(j)["orders"]]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 648, 649, 650, 651, 652, 653]
