Def c_to_f(): # FIXME return # FIXME: Finish temp_c = float(input('Enter temperature in Celsius: ')) temp_f = None # FIXME: Call conversion function # temp_f = ?? # FIXME: Print result # print('Fahrenheit:' , temp_f)

Explanation:

The first piece of code we can fill in is the formula to convert Celsius to Fahrenheit and return it as function output (Line 2).

The second fill-up code is to call the function c_to_f and pass temp_c as argument (Line 7). The temp_c will be processed in the function and an equivalent Fahrenheit value will be returned from the function and assigned it to temp_f.
