Question

我对python相对较新，而我唯一的其他体验是C ++。每当我在Python中定义一个函数时，我似乎无法执行它。这是我当前的作业代码，如果可能，我只想知道为什么我的代码不会执行

def birthexp(birthyear):
    product = birthyear**birthyear
    length = len(str(product))
    onesCount = str(product).count("1")
    threeCount = str(product).count("3")
    fiveCount = str(product).count("5")
    sevenCount = str(product).count("7")
    nineCount = str(product).count("9")
    sumCount = onesCount+threeCount+fiveCount+sevenCount+nineCount
    oneRation = onesCount/float(length)*100
    threeRatio = threeCount/float(length)*100
    fiveRatio = fiveCount/float(length)*100
    sevenRatio = sevenCount/float(length)*100
    nineRatio = nineCount/float(length)*100
    totalRatio = sumCount/float(length)*100
    print(str(product) + ": product after multiplying the birth year to itself.")
    print(str(onesCount) + ": number of ones found at a rate of " +str(oneRation)+ "percent.")
    print(str(threeCount) + ": number of threes found at a rate of " +str(threeRatio)+ "percent")
    print(str(fiveCount) + ": number of fives found at a rate of " +str(fiveRatio)+ "percent")
    print(str(sevenCount) + ": number of sevens found at a rate of " +str(sevenRatio)+ "percent")
    print(str(nineCount) + ": number of nine found at a rate of " +str(nineRatio)+ "percent")
    print(str(sumCount) + ": total odd numbers found at a rate of " +str(totalRatio)+ "percent")

birthyear(1990)

Answer 1

此行totalRatio = sumCount/floar(length)*100中有拼写错误。您需要float而不是floar。

其次，几乎所有使用print函数的行都有大量缺失的括号。

如果您希望该函数返回值，则应使用return代替print：

return (str(product)
            + ": product after multiplying the birth year to itself.\n"
            + str(onesCount)
            + ": number of ones found at a rate of " + str(oneRation) + "percent.\n"
            + str(threeCount)
            + ": number of threes found at a rate of " + str(threeRatio) + "percent\n"
            + str(fiveCount)
            + ": number of fives found at a rate of " + str(fiveRatio) + "percent\n"
            + str(sevenCount)
            + ": number of sevens found at a rate of " + str(sevenRatio) + "percent\n"
            + str(nineCount)
            + ": number of nine found at a rate of " + str(nineRatio) + "percent\n"
            + str(sumCount)
            + ": total odd numbers found at a rate of " + str(totalRatio) + "percent\n")
