Adding feature in Python/Fahrenheit_to_celsius.py [Convert user provided temperature]

[arpitbaheti2002]

Description:

I want to add a feature that allows the user to input temperature in Fahrenheit and the program converts it to celsius for that specific input.

Impact :

This will increase the useability of this program as this will allow users to quickly get the desired output rather than scrolling through all the outputs for different temperatures.

Required Changes :

• [ ] provide a choice to users to convert specific temperature or go through all the temperature conversions.
• [ ] If the user wants to convert a specific temperature to Celsius then ask for the temperature.
• [ ] Display desired result.

Notes :

I have read the CODE_OF_CONDUCT.md and CONTRIBUTING.md. Please assign the issue to me.

Pull Request :

I have made pull request #614 implementing this feature.
