如何修复*：'function'和'float'错误的不受支持的操作数类型

Question

我正在尝试计算极限试剂，但是一旦到达该行的那部分计算，我就会收到此错误：

gramOxygenAA = (moleOxygen * (2/1)) * ((12.011*2) + (1.008*4) + (15.9994 * 2))

这是我的代码：

# Function that determines moles of oxygen input
def moleOxygen (gramOxygen):
    moleOxygen = gramOxygen / (15.9994 * 2)
    print ("Moles of oxygen available:", format(moleOxygen,'.2f'))
    return (moleOxygen)


# Function that determines moles of acetaldehyde input
def moleAcetaldehyde (gramAcetaldehyde):
    moleAcetaldehyde = gramAcetaldehyde / ((12.011*2) + (1.008*4) + 15.999)
    print ("Moles of acetaldehyde available:", format(moleAcetaldehyde,'.2f'))
    return moleAcetaldehyde


# Function that determines grams of Acetic Acid produced from available oxygen
def gramOxygenAA (moleOxygen): 
    gramOxygenAA = (moleOxygen * (2/1)) * ((12.011*2) + (1.008*4) + (15.9994 * 2))
    print ("Grams of Acetic Acid that can be produced from available oxygen is", format(gramOxygenAA,'.2f'))
    return gramOxygenAA


# Function that determines grams of Acetic Acid produced from available acetaldehyde
def gramAcetaldehydeAA ():
    gramAcetaldehydeAA = (moleAcetaldehyde / (2/2)) *((12.011*2) + (1.008*4) + (15.9994 * 2))
    print ("Grams of Acetic Acid that can be produced from available acetaldehyde is", format(gramAcetaldehydeAA, '.2f'))
    return gramAcetaldehydeAA


# Function that determines the Limiting Reagent
def limitingReagent():
    if gramOxygenAA < gramAcetaldehydeAA:
        smaller = gramOxygenAA
        print ("Oxygen is the limiting reagent")

    else:
        smaller = gramAcetaldehydeAA
        print ("Acetaldehyde is the limiting reagent")

    return smaller


def main ():
    gramOxygen = float (input("Enter grams of oxygen entered into the reaction: "))
    gramAcetaldehyde = float (input("Enter grams of acetaldehyde entered into the reaction: "))

    print ("*" * 80)

    moleOxygen (gramOxygen)
    moleAcetaldehyde (gramAcetaldehyde)
    gramOxygenAA (moleOxygen)
    gramAcetaldehydeAA ()

    limitingReagent()
    print ("The number of grams of acetic acid produced due to limiting reagent is", format (smaller,'.2f'))

我编辑的更改代码：

# Function that determines moles of oxygen input
def moleOxygen (gramOxygen):
    molesOxygen = gramOxygen / (15.9994 * 2)
    print ("Moles of oxygen available:", format(molesOxygen,'.2f'))
    return (molesOxygen)


# Function that determines moles of acetaldehyde input
def moleAcetaldehyde (gramAcetaldehyde):
    molesAcetaldehyde = gramAcetaldehyde / ((12.011*2) + (1.008*4) + 15.999)
    print ("Moles of acetaldehyde available:", format(molesAcetaldehyde,'.2f'))
    return molesAcetaldehyde


# Function that determines grams of Acetic Acid produced from available oxygen
def gramOxygenAA (): 
    gramsOxygen = (moleOxygen * (2/1)) * ((12.011*2) + (1.008*4) + (15.9994 * 2))
    print ("Grams of Acetic Acid that can be produced from available oxygen is", format(gramsOxygenAA,'.2f'))
    return gramsOxygen


# Function that determines grams of Acetic Acid produced from available acetaldehyde
def gramAcetaldehydeAA ():
    gramsAcetaldehydeAA = (molesAcetaldehyde / (2/2)) *((12.011*2) + (1.008*4) + (15.9994 * 2))
    print ("Grams of Acetic Acid that can be produced from available acetaldehyde is", format(gramsAcetaldehydeAA, '.2f'))
    return gramsAcetaldehydeAA


# Function that determines the Limiting Reagent
def limitingReagent():
    if gramsOxygen < gramsAcetaldehydeAA:
        smaller = gramsOxygen
        print ("Oxygen is the limiting reagent")

    else:
        smaller = gramsAcetaldehydeAA
        print ("Acetaldehyde is the limiting reagent")

    return smaller


def main ():
    gramOxygen = float (input("Enter grams of oxygen entered into the reaction: "))
    gramAcetaldehyde = float (input("Enter grams of acetaldehyde entered into the reaction: "))

    print ("*" * 80)

    moleOxygen (gramOxygen)
    moleAcetaldehyde (gramAcetaldehyde)
    gramOxygenAA ()
    gramAcetaldehydeAA ()

    limitingReagent()
    print ("The number of grams of acetic acid produced due to limiting reagent is", format (smaller,'.2f'))

但是我仍然遇到相同的错误...太可悲了...
