AttributeError: 'dict' object has no attribute 'cpe_mac' : I'm trying to print out all the cpe_mac fields of my API via python.

I have

    import requests
    import json
    
    ssc_ip = raw_input("What is your SSC Host (Ex. http://172.19.242.32:1234/ ) ? : ")
    if not ssc_ip:
        ssc_ip = 'http://172.19.242.32:1234/'
    
    cpe_num = raw_input("How many CPE(s) you want to delete ? : ")
    print '\n'
    
    url = ssc_ip+'vse/vcpes'
    json_data = requests.get(url).json()
    # print json_data
    
    for x in json_data:
        print json_data.cpe_mac
