File Operation Example
The code is as follows:
#输入文件f = open (R ' D:\Python27\pro\123.bak ')#输出文件FW = open (R ' D:\Python27\pro\123e.bak ', ' W ')#按行读出所有文本lines = F.readlines ()num =-1For line in lines:str = ' @SES/%i/'%numline = Line.replace (' @SES/1/', str)num = num + 1#写入文件Fw.writelines (line)#关闭文件句柄F.close ()Fw.close ()

If we want to read a file into the StringBuffer and write the new file, the new file MD5 value needs to remain the same (the new file is guaranteed to be identical to the source file),We need to append the line break when manipulating StringBuffer:1StringBuffer SB =NewStringBuffer ();2Reader rd =NULL;3BufferedReader br =NULL;4 5RD =NewFileReader ("e:/" is a ladies ' boy. html ");6BR =NewBufferedReader (RD);
Example of a file operation
Copy Code code as follows:
#输入文件
f = open (R ' D:\Python27\pro\123.bak ')
#输出文件
FW = open (R ' D:\Python27\pro\123e.bak ', ' W ')
#按行读出所有文本
lines = F.readlines ()
num =-1
For line in lines:
str = ' @SES/%i/'%num
line = Line.replace (' @SES/1/', str)
num = num + 1
#写入文件
Fw.writelines (line)
#关闭文件句柄
F.close ()
Fw.close ()
