替换，循环，格式化并计算Python列表中的替换

Question

我需要编辑代码的帮助，因此输出最终如下所示：

输入目标词：红色

输入替换词：粉红色

更换数量：3

原始清单：

blue, red, yellow, green, red, black, white, gray, blue, blue, red

替换清单：

blue, pink, yellow, green, pink, black, white, gray, blue, blue, pink

基本上，我需要修复我的代码，以便我的原始列表和替换列表使用for循环，但是我还必须使用replace函数，并且同时我必须打印替换数量（我不这样做）不知道该怎么做）。
到目前为止，这是我的代码：

def replace (list1, target, replaceWord):
    new = ""
    for word in list1:
        if word == target:
            new += replaceWord + (", "[-1])
        else:
            new += word + (", "[-1])
    return new

def main():
    print ("Welcome! Enter your words one at a time and hit enter after each value.\nWhen you are done entering values, type stop.")
    inp = input ("Enter first value: ")
    list1 = []
    while inp !="stop":
        list1.append(inp)
        inp = input ("Enter first value: ")

    target = input ("Enter target word :")
    replaceWord =  input ("Enter replacement word: ")
    print()
    newlist = replace(list1,target,replaceWord)
    for i in newlist:
##     reps = ( )
##     reps += str (replaceWord)
    print ("Number of replacements: " +(reps))
    print ("Original list: " + (str (list1)))
    print ("List with replacement: " + newlist)

main()

请帮忙，非常感谢

def replace (list1, target, replaceWord):
    new = []
    replacements_no = 0
    for word in list1:
        if word == target:
            new.append(replaceWord)
            replacements_no += 1
        else:
            new.append(word)

    return new, replacements_no

def main():
    print ("Welcome! Enter your words one at a time and hit enter after each value.\nWhen you are done entering values, type stop.")
    inp = input ("Enter first value: ")
    list1 = []
    while inp !="stop":
        list1.append(inp)
        inp = input ("Enter first value: ")

    target = input("Enter targe word :")
    replaceWord = input("Enter replacement word: ")
    print()
    newlist, replacements = replace(list1,target,replaceWord)
    print("Number of replacements: {}".format(replacements))
    print ("Original list: " + (str (list1)))
    print ("List with replacement: {}".format(', '.join(newlist)))

main()

这样的事情应该起作用。 您不必在替换功能中放在一起，可以建立新列表。
