The x mode can be used in the open() function in the following way. This mode is significant and comes in handy when we donât want to accidentally truncate an already existing file with the a or w modes. In the x mode, the file is only writeable, but in x+ mode, the file is opened as both readable and writeable. When exclusive creation is specified, it means that this mode will not create a file if the file with the specified name already exists. The x mode opens the file for exclusive creation, failing if the file with that name is already existent. This mode is available for the versions Python 3 and above. f1 = open("god.txt", "a+")įor opening the file in binary mode, we can add the ab+ mode. The a+ mode can be used in the open() function in the following way. If the file does not exist, then it is created for writing. The file pointer in this mode is placed at the end of the file if it already exists in the system. The a+ mode opens the file for both reading and appending. The a mode can be used in the open() function in the following way. The a mode opens the file for the purpose of appending. f1 = open("god.txt", "w+")įor opening the file in binary format, we can use the wb+ mode. The w+ mode can be used in the open() function in the following way. The file pointer in this mode is placed at the starting point of the file. If the file already exists, it is truncated, and otherwise, a new file is created if it doesnât exist. The w+ mode opens the file for reading and writing. The w mode can be used in the open() function in the following way: f1 = open("god.txt", "w") If the file already exists, it truncates the file to zero length and otherwise creates a new file if it doesnât exist yet. The w mode is used to open a file for the purpose of writing only. The r+ mode can be used in the open() function in the following way: f1 = open("god.txt", "r+")įor opening the file for writing and reading in the binary format, we can use the rb+ mode. Just like in the previous mode, the file pointer in this mode is placed at the starting point of the file as well. The r+ mode is used to open a file for both reading and writing. The r mode can be used in the open() function in the following way: f1 = open("god.txt", "r") The r mode is used when we want to open the file for reading. In this tutorial, we will learn about the different modes in which a file can be opened in Python. Use one of the following lines to open a file in append mode: f open ('', 'a') Text append f open ('', 'at') Same as above f open ('', 'ab') Binary append Add the + sign to include the read functionality.The open() function mainly takes two parameters, filename and mode. It is used to open the file and return an equivalent file object. The handiest and most important function in dealing with files is the open() function. The following table lists the file access modes parameter values.Reading and Writing To Files in Python (Video 41) ![]()
