This python code isn't working for me and I do not know why. Tell me if there any promblem with the code

Question

I don't know why this python code isn't working, please tell me why.

weight = int(input("Enter your weight:"))
Weightscale = (input("(L)bs or (K)g:"))

if Weightscale.lower == "L":
                  ans = (weight * 0.45)
                  print(f"You are {ans} Kg")

else:
    ans = (weight / 0.45)
    print(f"You are {ans} pound")

Answer 1

You should declare weight as a float to have decimal values.

You must use () to call lower . Then your lower condition must compare to a lowercase letter "l" , not "L" :

weightscale = input("(L)bs or (K)g: ")
weight = float(input(f"Enter weight in {weightscale}: "))

# Lower needs (), then make the "L" lower too -> "l"
if weightscale.lower() == "l":
    ans = (weight * 0.45)
    print(f"You are {ans} Kg")

else:
    ans = (weight / 0.45)
    print(f"You are {ans} pound")

Answer 2

I notice three mistakes in your code:

• weight is not declared

• Weightscale.lower should be a function call, ie Weightscale.lower()

• Weightscale.lower() will never be equal to "L" , so your if block will never be treated. You should do one of the following:

  • Weightscale.lower() == "l"
  • Weightscale.upper() == "L"

Answer 3

使用较低并比较“L”，尝试：

if Weightscale.lower() == "l":
