把.doc,.docx變爲txt工具：

操作過程:https://www.jianshu.com/p/1e8af633fc08

f = open('C:/Users/Administrator/Desktop/新建文件夾/各講練習題/轉化/第一講.txt','r',encoding='UTF-8')
#with open('C:/Users/Administrator/Desktop/1.txt','r',encoding='UTF-8') as f:  # 打開新的文本
#text_new = f.read()  # 讀取文本數據
lines = f.readlines()
i=0
for line in lines:
    if "答" in line:
        i=i+1
        print("第{name}題, {url}".format(name=i, url=line))

#優化思路：將答案轉入到list或者DF，然後input答題輸出答案結果
