d = {'surname':"Doe",'name':"Jane",'prefix':"Dr."}
f"""{d['prefix'] or ''} {d['name'][0] '. ' or ''}{d['surname']}"""

works, however

d = {'surname':"Doe",'name':None,'prefix':"Dr."}
f"""{d['prefix'] or ''} {d['name'][0] '. ' or ''}{d['surname']}"""

does not of course. How can I parse values from a dictionary conditionally? Or are there other work-arounds? I am iterating through a list of dictionaries with a lot of entries each so editing the data beforehand is not really an option here.

CodePudding user response：

Simply add a condition inside f string

f"""{d['prefix'] or ''} {d['surname'][0] '. ' if d['surname'] is not None else ''}{d['name']}"""

CodePudding user response：

Use condition to check if name has value.

f"""{d['name'][0] if d.get('name') else None}"""

CodePudding user response：

use if in f-string

f"{d['prefix'] or ''} {d['name'] if d['name'] != None else ''}. {d['surname']}"
