需求描述
现在有一个文件夹，文件夹中有几百个markdown文件，我们想在每一个文件的第二行和第三行，分别添加date和title属性。
python如何读取markdown文件
我们只需使用open函数即可，但是在解码格式上年一定要采用UTF-8，否则会报错
如何获取文件的创建时间
t = os.path.getmtime(filePath + '\\' + i) 复制代码
如何得到文件指定行的内容(通过linecache这个包)
import linecache categories_add = 'categories: ' + linecache.getline(filePath + '\\' + i, 5).strip()[2:] 复制代码
全部代码
import os import time import linecache filePath = 'G:\HEXO\添加文件名和时间\\test' def TimeStampToTime(timestamp): timeStruct = time.localtime(timestamp) return time.strftime('%Y-%m-%d',timeStruct) for i in os.listdir(filePath): print(i) t = os.path.getmtime(filePath + '\\' + i) print(TimeStampToTime(t)) file = open(filePath + '\\' + i, "r",encoding='utf-8') text = file.read() # print(text) content_add = i[:-3] text_add = TimeStampToTime(t) pointer = text.find("date:") pos = text.find("title:") categories_add = 'categories: ' + linecache.getline(filePath + '\\' + i, 5).strip()[2:] print(categories_add) if pointer != -1 & pos != -1: # text = text[:pointer+6] + text_add + text[pointer+6:] # text = text[:pos+7] + content_add + text[pos+7:] tagP = text.find("tags:") text = text[:tagP] + categories_add + '\n' + text[tagP:] file = open(filePath + '\\' + i, "w",encoding='utf-8') file.write(text) file.close() # 下面的是写入标题 # print(i[:-3]) # file = open(filePath + '\\' + i, "r",encoding='utf-8') # content = file.read() # content_add = i[:-3] # pos = content.find("title:") # if pos != -1: # content = content[:pos+6] + content_add + content[pos+6:] # file = open(filePath + '\\' + i, "w") # file.write(content) # file.close()
