[Python] How to reduce the nested block dictionary in python

I have sample dictionary is below

How to reduce the Loop because Its more than 5 blocks and pylint its failing

Below are the conditions need to checked

• 
  Checking whether People Key exists
  
  
• 
  if 'People' exist then looping
  
  
• 
  checking whether 'role_id' exists in People
  
  
• 
  return base dictionary id if role_id is None
  
  
• 
  checking Role is available in event dictionary
  
  
• 
  if Role not available then pass base Developer
  
  
• 
  if Role key present then take roleName from the Role
  
  
• 
  If 'Tester' == roleName available then create a new dictionary
  
  event = {
  "id": "100",
  "Dept": "Developer",
  "Role": [{
  "id": "201",
  "roleName": "UI"
  },
  {
  "id": "202",
  "roleName": "Tester"
  }
  ],
  "People": [{
  "id": "290",
  "fullName": "Jo",
  "email": "jo@test.com",
  "role_id": [{
  "S": "201"
  },
  {
  "S": "202"
  }
  ]
  }]
  
  
  }
  

Code is below which is working

def get_dict(event):
total_list = ['Tester','Developer']
Developer = {'id':None}
if 'People' in event: #Checking whether People Key exists
for people in event['People']: # if 'People' exist then looping
if people['role_id'] is None: #checking whether 'role_id' exists
return Developer #return base dictionary id role_id None
for role_id in people['role_id']: #if not None
if 'Role' not in event: #checking ROle is available in event dictionary
return Developer #if not then pass base Developer
for role in event['Role']: #if Role key present
if role['id'] == role_id['S']:
role_name = role['roleName']
if role_name in total_list:
if "Tester" == role_name:
Developer = {'id': event['People'][0]['id'],
'role':role_name}
return Developer
get_dict(event)


My output and Expected

{'id': '290', 'role': 'Tester'}


My Problem I am facing. How to reduce the Loop because Its more than 5 blocks and pylint its failing?

p.s. Yes, it is my coding intention to exit immediately if the first people doesn't have a role_id.
