Def problem, plz help, thank you

Question

celsius = int(input())

def conv(c):
print(9/5*c+32)
#your code goes here

fahrenheit = conv(celsius)
print(fahrenheit)

#may i ask why there is a none in the output??

Answer 1

because the `conv` function does not return a value, so by default it returns None every time is called.
To fix this just modify the line as: `return 9/5*c+32`
