I did not realize that the first nested element is actually an array  The correct way access to the post code key is as follows   r   requests get  http   api zippopotam us us ma belmont   j   r json    print j  state   print j  places   1   post code

In your code j is Already json data and j  places   is list not dict         r   requests get  http   api zippopotam us us ma belmont    j   r json     print j  state    for each in j  places        print each  latitude

Places is a list and not a dictionary  This line below should therefore not work   print data  places    latitude     You need to select one of the items in places and then you can list the place s properties  So to get the first post code you d do   print data  places   0   post code
