• <file.mode> returns the access mode in which the file was opened. Activity 2.2 • <file.name> returns the name of the file. Some of the other The file_name should be the name of the file that file access modes are <rb+>, <wb>, <w+>, has to be opened. If the file is not in the current working directory, then we need to specify the complete path of <ab>, <ab+>. Find out for what purpose each the file along with its name. of these are used. The access_mode is an optional argument that Also, find the file offset positions in represents the mode in which the file has to be accessed each case. by the program. It is also referred to as processing mode. Here mode means the operation for which the file has to be opened like <r> for reading, <w> for writing, <+> for both reading and writing, <a> for appending at the end of an existing file. The default is the read mode. In addition, we can specify whether the file will be handled as binary (<b>) or text mode. By default, files are opened in text mode that means strings can be read or written. Files containing non-textual data are opened in binary mode that means read/write are performed in terms of bytes. Table 2.1 lists various file access modes that can be used with the open() method. The file offset position in the table refers to the position of the file object when the file is opened in a particular mode. Table 2.1 File Open Modes File Mode Description File Offset position <r> Opens the file in read-only mode. Beginning of the file <rb> Opens the file in binary and read-only mode. Beginning of the file <r+> or <+r> Opens the file in both read and write mode. Beginning of the file <w> Opens the file in write mode. If the file already exists, all theg of the file contents will be overwritten. If the file doesn’t exist, then a new file will be created. <wb+> or Opens the file in read,write and binary mode. If the file Beginning of the file <+wb> already exists, the contents will be overwritten. If the file doesn’t exist, then a new file will be created. <a> Opens the file in append mode. If the file doesn’t exist, then End of the file a new file will be created. <a+> or <+a> Opens the file in append and read mode. If the file doesn’t End of the file exist, then it will create a new file. Consider the following example. myObject=open(“myfile.txt”, “a+”) 22 Computer Science - ClassXII Reprint 2026-27
