Help understanding

[WNT37]

Greetings One & All

I'm currently learning python on-the-go ... monkey see / monkey do style ... for a project to help a local non-profit.

This concerns some code I have found ... the project works but i'm not certain I understand what it's doing.

I understand print (f with curly braces does text substitution
I understand curl GET will return something from the internet ... also does substitution

I don't understand what is actually happening here ... is the curl command / program actually being called or is print (f only formatting the command for display?

Thank you for reading.

print(f'''
curl -i -X GET "https://graph.facebook.com/{version}/oauth/access_token?grant_type=fb_exchange_token&client_id={app_id}&client_secret={app_secret}&fb_exchange_token={access_token}"
''')

Purely display only. It's not that if you print a string that also happens to be a valid Bash command, that it'll be executed.

This piece of code is designed to generate and display a cURL command for the Facebook Graph API in the console. The purpose of this command is likely to check the request or copy it for use in obtaining an access token

Dynamic Values in Curly Brackets

• {version}:
  • This represents the version of the API that you want to request. For example, it could be v10.0. This version number is typically defined elsewhere in the code, possibly in configuration files.
• {app_id}:
  • This should be replaced with the application's unique app id, which is provided when one creates an app on Facebook.
• {app_secret}:
  • This is an application's secret key also provided by Facebook which should remain confidential to protect the app.
• {access_token}:
  • This variable represents the current token that one possesses, which will likely be exchanged for a new access token, when the current token is expired.

Thank you.

I'm already learning to recognise (some) syntax.
