How can I merge two dictionaries meeting a condition

For example:

I have two dictionaries:

dict1 = {'machine1': {'operative_system': 'Windows', 'Description':'This is an example'} 'machine2': {'operative_system': 'Ubuntu', 'Description':'This is another example'}}

dict2 = {'machine1': {'Disk1': {'Name_disk':'example'}, 'Disk2': {'Name_disk':'disk2'}}}

How can I insert those "disks" into the first dictionary?

The names of the machines are the same...

You could use dict.update to update the existing sub-dictionaries from dict1, and wrap in a try/except to handle KeyError when not in dict2

for key, value in dict1.items():
    try:
        value.update(dict2[key])
    except KeyError:
        continue

Afterwards

>>> dict1
{'machine1': {'operative_system': 'Windows',
              'Description': 'This is an example',
              'Disk1': {'Name_disk': 'example'},
              'Disk2': {'Name_disk': 'disk2'}},
 'machine2': {'operative_system': 'Ubuntu',
              'Description': 'This is another example'}}

Similarly the following would also work

for key, value in dict1.items():
    if key in dict2:
        value.update(dict2[key])
