How to add prefix/suffix on a repeatable dictionary key in Python

Could you please suggest is there any way to keep all the repeatable (duplicate) keys by adding prefix or suffix. In the below example, the address key is duplicated 3 times. It may vary (1 to 3 times). I want to get the output as in the expected output with adding a suffix to make the key unique. Currently the update function is overwriting the key value.

list = ['name:John','age:25','Address:Chicago','Address:Phoenix','Address:Washington','email:John@email.com']
dic = {}
for i in list:
    j=i.split(':')
    dic.update({j[0]:j[1]})
print(dic)

Current output: {'name': 'John', 'age': '25', 'Address': 'Washington', 'email': 'John@email.com'}

Expected output: {'name': 'John', 'age': '25', 'Address1': 'Chicago', 'Address2': 'Phoenix', 'Address3': 'Washington', 'email': 'John@email.com'}

Tried the below:

list = ['name:John','age:25','Address:Chicago','Address:Phoenix','Address:Washington','email:John@email.com']
dic = {}
for i in list:
    j=i.split(':')
    dic.update({j[0]:j[1]})
print(dic)

Expected output: {'name': 'John', 'age': '25', 'Address1': 'Chicago', 'Address2': 'Phoenix', 'Address3': 'Washington', 'email': 'John@email.com'}

You can use something like this:

list_ = ['name:John','age:25','Address:Chicago','Address:Phoenix','Address:Washington','email:John@email.com']

dic = {}
for i in list_:
    j = i.split(':')
    key_ = j[0]
    count = 0 # counts the number of duplicates
    while key_ in dic:
        count += 1
        key_ = j[0] + str(count)
    dic[key_] = j[1]

Output:

{'name': 'John',
 'age': '25',
 'Address': 'Chicago',
 'Address1': 'Phoenix',
 'Address2': 'Washington',
 'email': 'John@email.com'}

PS. don't use the python keyword list to name your variables as it overrides the type list
