Why my program returning ans with none.

Question

def function(celsius):
celsius=float(input())
fahrenheit= 1.8 *celsius + 32
print(fahrenheit)
print(function (36))

Answer 1

In Python any function or method that does not explicitly return a value will by default return None. Since function() does not explicitly return anything then None is returned from the call to function().
Try this instead;
def func(celsius):
return float(celsius) * 1.8 + 32
print(func(36))

Answer 2

Your function doesn't return any value to calling print function. So none will be printed

Answer 3

It is answering with "none" because you have no return value in your defined function.
You have to do this.
def function():
celsius=float(input())
fahrenheit= 1.8 *celsius + 32
return fahrenheit
print(function())
