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。

In the example, we read the contents of the file with readlines. We print the list of the lines and then loop over the list with a for statement. $ ./read_lines.py ['Lost Illusions\n', 'Beatrix\n', 'Honorine\n', 'The firm of Nucingen\n', 'Old Goriot\n', 'Colonel Chabert\...
#write lines to file with proper line-ending fobj = open(fname, 'w') fobj.writelines(['%s%s' %(x,ls) for x in all]) fobj.close() print ('Done') 程序验证: 文本查看器查看: 2.读取文本文件(readtext.py) 程序如下: #read and dislay text file print("read and dislay text file") ...
In the following example: Theopen()function opens the file nameddata.txtin read mode ('r'). Thereadlines()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. ...
