Within the code above whenever I type in “L” or “l” into the terminal I’m given the results for the Kgs when it should produce the results for the Lbs
Though when I instead use( As hopefully shown in script2.py)
weight = float(input("Weight: “))
unit = input(”(K)g or (L)bs: ")
if unit.upper() == == “K”:
weight *= .45
print("Weight in kgs: " + str(weight))
elif unit.upper() == “L”:
weight /= .45
print("Weight in lbs: " + str(weight))
else:
Print(‘error’)
The code works perfectly fine and was wondering why this is?

Your condition
if unit == "K" or "k":
is equivalent to
if (unit == "K") or ("k"):
The second operand ("k") is truthy. Therefore the above condition will always evaluate to True irrespective of the value assigned to unit.
(See the paragraph titled “Truth Value Testing” in the documentation to see which values are considered Falsy. The rest are Truthy).
If you wish, you can write the condition as:
if (unit == "K") or (unit == "k"):
