Input & Output to Console

input(__parameter__) is a built-in function that is able to grab keyboard based input from the console.

The input() function has an optional parameter which takes a single string. This string can be considered as a prompting message to help users identify what type of data to input.

print(__parameter__) is a built-in function that helps to output a message to the console.

The print() function can take any number of parameters separated by commas. This will output such parameters separated by a whitespace into the console.

# Fahrenheit to Celsius Converter

fahrenheit = input("Enter a fahrenheit value: ")
fahrenheit = float(fahrenheit)

celsius = (fahrenheit - 32.0) * (5/9)

print(fahrenheit, "is converted to:", celsius, "in celsius")

Code Explanation

fahrenheit = input("Enter a fahrenheit value: ")
fahrenheit = float(fahrenheit)

• The first line prompts the user to enter a Fahrenheit value.

• The input function is used to read the user's input, which is initially a string.

• The second line converts the input value from a string to a floating-point number using the float() function and assigns it to the variable fahrenheit.

celsius = (fahrenheit - 32.0) * (5/9)

• The next line calculates the Celsius equivalent of the Fahrenheit value.

• The formula used is (Fahrenheit - 32) * (5/9) to convert Fahrenheit to Celsius.

• The result is assigned to the variable celsius.

print(fahrenheit, "is converted to:", celsius, "in celsius")

• Finally, the last line displays the original Fahrenheit value entered by the user, along with the converted Celsius value.

• The print() function is used to output the values to the console.

• The values are separated by commas, which are automatically converted to strings and concatenated.
