What's wrong with this code?

Question

I'm not too sure what's wrong with this

def initial():
initial_unit = str(input("Enter the unit you currently have"))
final_unit = str(input("Enter the unit you want to get"))
if initial_unit == "stones" and final_unit == "kg":
print(from_stones_to_kg())
elif initial_unit == "pounds" and final_unit == "kg":
from_pounds_to_kg(int)
elif initial_unit == "kg" and final_unit == "stones":
from_kg_to_stones(int)
elif initial_unit == "kg" and final_unit == "pounds":
from_kg_to_pounds(int)
else:
return False

initial()

def from_stones_to_kg(stones):
if stones != 0:
newweight = stones * 6.35029
return newweight
else:
return 0

def from_pounds_to_kg(pounds):
if pounds != 0:
newweight = pounds * 0.453592
return newweight
else:
return 0

def from_kg_to_stones(kg):
if kg != 0:
newweight = kg / 6.35029
return newweight
else:
return 0

def from_kg_to_pounds(kg):
if kg != 0:
newweight = kg / 0.453592
return newweight
else:
return 0

kg = int(input("Enter the number of kg"))
pounds = int(input("Enter the number of pounds"))
stones = int(input("Enter the number of stones"))

Thanks

Answer 1

You either have to define from_stones_to_kg() etc. before initial() or call initial() after you defined these functions. Otherwise you can't call the functions from initial(), because initial() doesn't "know" what these functions are.

In lines 2 and 3 you convert the input to a string. That's not necessary as any user input will be a string by default.

In line 5, you call from_stones_to_kg() without a parameter, but the function definition says that from_stones_to_kg() needs a parameter "kg".

In lines 7, 9 and 11 you call functions with a parameter "int". int is a datatype. You need to call the function with a specific value instead. Maybe you want to do something like from_kg_to_stones(int(input('Enter the initial value'))). Also, you call the functions but you don't print their return value. So there will be no output.

This is the correct code with why I correcred everything
