Creating a dynamic dictionary name

Question

Very new to Python. I'm trying to dynamically create new dictionaries inside of a FOR LOOP with dictionary names that are derived from the first element of a LIST inside another list.

My goal is to end up with a data structure that looks like this:

router1 = {'Hostname': 'router1',
         'OS-Type': 'ios',
         'IP Address': '1.1.1.1',
         'Username': 'user1',
         'Password': 'cisco',}

router2 = {'Hostname': 'router2',
         'OS-Type': 'ios',
         'IP Address': '1.1.1.2',
         'Username': 'user2',
         'Password': 'cisco',}

sw1 = {'Hostname': 'sw1',
         'OS-Type': 'cat-os',
         'IP Address': '1.1.1.3',
         'Username': 'user3',
         'Password': 'cisco',}

These dictionaries would later be added to a LIST:

dictionary_list = [router1, router2, sw1]

Here's what my FOR LOOP currently looks like:

for i in range(len(device_list)):    
    dynamic_dictionary = {'Hostname': device_list[i][0],    
                          'OS-Type': device_list[i][1],    
                          'IP Address': device_list[i][2],    
                          'Username': device_list[i][3],    
                          'Password': device_list[i][4]}

Any help would be greatly appreciated.

Thanks!

Why not append the dictionaries you are creating to a list right away. In addition, define the list of keys before hand, so that you can append the dictionary while iterating over the list of keys

li = []
keys = ['Hostname', 'OS-Type', 'IP Address', 'Username', 'Password']
for i in range(len(device_list)):
    dct = {}
    for idx, key in enumerate(keys):
        dct[key] =  device_list[i][idx]
    li.append(dct)
