How to convert a dictionary of contacts into a vcard (*.vcf file)?

Question

I am working on some vcard files in python. I have parsed vcard file into a dictionary. Now I want to save it to a new vcf file after editing it. I couldn't find any solution to this. Is there any library or module which parse python dictionary in vcards ?

person = {'n': 'Forrest Gump',
          'fn': 'Forrest Gump', 'tel': '(111) 555-1212',
          'email': '[email protected]',
          'photo': ';http://www.example.com/dir_photos/my_photo.gif',
          'adr': 'Kathmandu, Nepal'}

I want to get a vcf file like the following when I give this dictionary.

BEGIN:VCARD
VERSION:3.0
N:Gump;Forrest;;Mr.;
FN:Forrest Gump
TITLE:Shrimp Man
PHOTO;VALUE=URI;TYPE=GIF:;http://www.example.com/dir_photos/my_photo.gif
EMAIL:[email protected]
END:VCARD

You should probably take a look at vobject here http://eventable.github.io/vobject/

import vobject

person = {'n': 'Forrest Gump',
          'fn': 'Forrest Gump', 'tel': '(111) 555-1212',
          'email': '[email protected]',
          'photo': ';http://www.example.com/dir_photos/my_photo.gif',
          'adr': 'Kathmandu, Nepal'}

vcard = vobject.readOne('\n'.join([f'{k}:{v}' for k, v in person.items()]))
vcard.name = 'VCARD'
vcard.useBegin = True
vcard.prettyPrint()

with open('test.vcf', 'w', newline='') as f:
    f.write(vcard.serialize())

Note that writing the card without .name and .useBegin set will omit the BEGIN and END and the resulting file will not be a valid vCard. I'm not sure if there's a more convenient way to do this using this library, but you could simply create your own class that inherits from the existing one (or call the function from a new one) to clean up the code.
