Open a File in Python

# Opening a File in Python Python is a widely used high-level programming language used for general-purpose programming. It is an interpreted language, with a large and comprehensive standard library. One of the core features of Python is its ability to read, write and manipulate files. In this article, we will explore how to open a file in Python. Opening a file in Python requires the built-in open() function. This function enables us to open a file, read or write to it, and then close it. The open() function takes in two parameters: the file name and the mode of file access. The mode of file access can be either read-only (r), write-only (w), or read-write (r+). The syntax for the open() function is as follows: ``` file_object = open("filename", "mode") ``` Here, the file_object is the name of the object of the file that we are opening. The filename refers to the file that we want to open, and the mode is the mode of file access. We can then use the file_object to read or write to the file. The read() method is used to read the contents of a file, while the write() method is used to write content to a file. After we are done writing or reading the file, we need to close it. We can do this using the close() method. This will ensure that any data written is properly saved. By using the open() function, we can easily open and manipulate files in Python. It is a useful tool for performing basic file operations such as reading, writing, and closing files.
