python写入doc文件 python 写入文本文档

• 新建、写入：

# 创建一个txt文件，文件名为first file,并向文件写入msg

def File_New(name, msg):
    desktop_path = "路径" #文件路径
    full_path = desktop_path + name + '.txt' # 也可以是.doc
    file = open(full_path,'w')
    file.write(msg)
    file.close()
text_create('first file', 'Hi!Python!')

# 调用函数创建一个名为first file的.txt文件，并向其写入Hi!Pythpn!

• 修改：

def UpdateFile(file,old,new):
    file_data = "路径"
    with open(file, "r", encoding="utf-8") as f:
        for line in f:
            if old_str in line:
                line = line.replace(old,new)
            file_data += line
    with open(file,"w",encoding="utf-8") as f:
        f.write(file_data)

 

UpdateFile(r"路径\first file.txt", "zdz", "administrator")#将路径中的first file.txt文件把所有的zdz改为administrator
