4/17/2023 0 Comments Open any file![]() Note: Since we don't have to worry about closing the file, make a habit of using the with.open syntax. For example, with open("test.txt", "r") as file1: In Python, we can use the with.open syntax to automatically close the file. Here, we have closed the file in the finally block as finally always executes, and the file will be closed even if an exception occurs. ![]() A safer way is to use a try.finally block. If an exception occurs when we are performing some operation with the file, the code exits without closing the file. Here, we have used the close() method to close the file.Īfter we perform file operation, we should always close the file it's a good programming practice. It is done using the close() method in Python. When we are done with performing operations on the file, we need to properly close the file.Ĭlosing a file will free up the resources that were tied with the file. Here, file1.read() reads the test.txt file and is stored in the read_content variable. Notice the code, read_content = file1.read In the above example, we have read the test.txt file that is available in our current directory. Here, we have explicitly specified the mode by passing the "r" argument which means file is opened for reading. The code above is equivalent to file1 = open("test.txt", "r") This object can be used to work with files and directories.īy default, the files are open in read mode (cannot be modified). Here, we have created a file object named file1. Now, let's try to open data from this file using the open() function. To demonstrate how we open files in Python, let's suppose we have a file named test.txt with the following content. In Python, we use the open() method to open files. ![]() ![]() Hence, in Python, a file operation takes place in the following order: When we are done, it needs to be closed so that the resources that are tied with the file are freed. When we want to read from or write to a file, we need to open it first. A file is a container in computer storage devices used for storing data. ![]()
