Question

我在文本文件中有这个菜单：

#Menu 1 file
Jelly Fish Yee Sang with Pear
Dried Seafood with Fish Soup
Steamed Sea Water Grouper

我有这段代码：

menuList = input('enter number:')
def printPackage(menuList):
    if menuList == '1':
        with open('menu/Menu1.txt')as f:
            data = f.read()
            print(data)
printPackage(menuList)

我应该在代码中添加什么内容，以便将文本文件打印出来？

---------
Menu List
---------
1. Jelly Fish Yee Sang with Pear
2. Dried Seafood with Fish Soup
3. Steamed Sea Water Grouper

请帮助。

尝试这种Pythonic WAY （更快）：

get_input = input('Enter Number: ')
if not get_input == "1":
    exit()
write_save = open("menu/result.txt", "a")
read_lines = [write_save.write("{}. {}{}".format(counts, line.rstrip("\n"), "\n")) for counts, line in enumerate(open('menu/Menu1.txt'), 1)]
write_save.close()

甚至更短：

get_input = input('Enter Number: ')
if not get_input == "1":
    exit()
read_lines = [open("result.txt", "a").write("{}. {}{}".format(counts, line.rstrip("\n"), "\n")) for counts, line in enumerate(open('Menu1.txt'), 1)]

JUST ONE LINE（LOOL）：

if input("Enter Number: ") == "1" : [open("result.txt", "a").write("{}. {}{}".format(counts, line.rstrip("\n"), "\n")) for counts, line in enumerate(open('Menu1.txt'), 1)]

如何在文本文件中的单词前添加数字？
