readlines() :Reads all the lines and return them as each line a string element in a list. File_object.readlines() file.read() 读取文件的所有内容,并以变量的形式返回。如:f = file.read()。这里file是目标文件,打开时需要设置可读模式。
The open() function opens the file named data.txt in read mode ('r'). The readlines() method reads all the lines of the file and returns them as a list of strings. Next, we can use a loop to iterate over the lines and process them sequentially. try: with open('data.txt', '...

file 表示 文件路经,可以是绝对路径(绝对安全),也可以是相对路径(取决于你的当前路径和文件路径) mode 表示 文件操作三种模式 r(read):仅读 t(text):读写文本信息时,直接使用utf-8编码进行压缩存储 w(write):仅写,文件不存在则会自动创建文件,每一次写入都会先清空再写入 ...
