from smtpd import program

Put functions at the top of the program
'''

def fahrenheit(celsius):
    '''Returns the input Celsius degrees in Fahrenheit'''
    return 9/5 * celsius + 32

def celsius(fahrenheit):
    '''Returns the input Fahrenheit degrees in Celsius'''
    return 5/9 * (fahrenheit - 32)

'''
Call the functions below the function definitions
'''
c = float(input("Enter the degrees in Celsius: "))
f = fahrenheit(c)
# You can print multiple items in one statement if you put a comma after each 
#item, it prints a space and then goes on to print the next item
print(c, 'C =', f, 'F')
#You can print this way too, but allowing exactly two decimal places
print('%.2f C = %.2f F' %(c,f))

f = float(input("Enter the degrees in Fahrenheit: "))
c = celsius(f)
print(f,'F =', c,'C')
print('%.2f F = %.2f C' %(f,c))

''' 
Try composition of functions.
Converting a Fahrenheit temperature to Celsius and back to Fahrenheit should
give you the original Fahrenheit temperature
'''

print() #print by itself prints a new line
f = float(input("Enter the degrees in Fahrenheit: "))

#Use assert to check if the returned value if equal to the expected value
assert(fahrenheit(celsius(f)) == f)
#No output should be produced unless the assertion fails which means you have 
#error either in your code or in your expectation
