如何将字典中的一些键分组到python中的嵌套键?

我有一本字典清单

[{
'LoanID' : 001,
'Applicant_Income.1' : 5000,
'Applicant_Occupation.1' : "Manager",
'Applicant_Income.2' : 3000,
'Applicant_Occupation.2' : "Accountant",
'LoanAmount' : 10000
},
{
'LoanID' : 002,
'Applicant_Income.1' : 6000,
'Applicant_Occupation.1' : "Senior Manager",
'Applicant_Income.2' : 2000,
'Applicant_Occupation.2' : "Services",
'LoanAmount' : 8000
}]

我需要创建一个新的键“申请人”,并将“申请人收入”和“申请人职业”移到其中,结果列表中的每个dict如下所示

{
'LoanID' : 001,
'Applicant' : [
     { 
       'Applicant_Income' : 5000,
       'Applicant_Occupation' : "Manager"
     }'
     {
       'Applicant_Income' : 3000,
       'Applicant_Occupation' : "Accountant"
     }]
'LoanAmount' : 10000
},
{
'LoanID' : 002,
'Applicant' : [
     { 
       'Applicant_Income' : 6000,
       'Applicant_Occupation' : "Senior Manager"
     }'
     {
       'Applicant_Income' : 2000,
       'Applicant_Occupation' : "Services"
     }]
'LoanAmount' : 8000
}
