Answer :
Here is a simple Python program to convert temperatures from degrees Fahrenheit to degrees Celsius:
```python
def fahrenheit_to_celsius(fahrenheit):
celsius = (fahrenheit - 32) * (5/9)
return celsius
# Test the function
fahrenheit = 98.6
celsius = fahrenheit_to_celsius(fahrenheit)
print("Temperature in Celsius:", celsius)
```
This Python program defines a function `fahrenheit_to_celsius` that takes a temperature in Fahrenheit as input and returns the equivalent temperature in Celsius. The formula `(fahrenheit - 32) * (5/9)` is used to perform the conversion. First, it subtracts 32 from the Fahrenheit temperature to adjust the scale, and then it multiplies by `(5/9)` to convert the adjusted temperature to Celsius.
In the provided example, the function is tested with a Fahrenheit temperature of 98.6, which is equivalent to normal body temperature. The calculated Celsius temperature is then printed to the console. This program demonstrates a straightforward way to perform Fahrenheit to Celsius conversions in Python, making it useful for various applications where temperature conversions are needed.
