List of dictionary need to split and take first only value after slit-CodePudding

I have list of dictionary in Python that i want to convert to another list after i split the value in the dictionary and take only first value after the split.

myList = [
  {'name': 'CN=John,Li', 
   'type': 'Agent', 
   'isMember': False},
  {'name': 'CN=Moses,Somewhere', 
   'type': 'Worker', 
   'isMember': True},
  {'name': 'CN=David, Something', 
   'type': 'Agent', 
   'isMember': False}
]


required_fields = ['name', 'isMember']

I'm looking for desired output after splitting the values

myList = [
  {'name': 'John', 
   'isMember': False},
  {'name': 'Moses', 
   'isMember': True},
  {'name': 'David', 
   'isMember': False}
]

Thank you in advance

A small helper function to find the CN=... part from the name, and a list comprehension to loop over myList:

import re


def get_cn(name):
    return re.search("CN=([^,] )", name).group(1)


my_list = [...]

new_list = [
    {'name': get_cn(x['name']), 'isMember': x['isMember']}
    for x 
    in my_list
]

print(new_list)

This outputs

[{'name': 'John', 'isMember': False}, {'name': 'Moses', 'isMember': True}, {'name': 'David', 'isMember': False}]

This can be done in single liner -->

new_list = []
for i in range(len(myList)):
    new_list.append({"name": re.search("CN=([^,] )", myList[i]['name']).group(1), \
                     "isMember":myList[i]['isMember']})
print(new_list)
