For example: "wb" means writing in binary mode. To use text or binary mode, you would need to add these characters to the main mode. That single character basically tells Python what you are planning to do with the file in your program. The second parameter of the open() function is the mode, a string with one character. txt that follow the dot in names.txt is the "extension" of the file, or its type. Notice that we are writing data/ first (the name of the folder followed by a /) and then names.txt (the name of the file with the extension). In this example, this would be the path: open("data/names.txt") Then we need to use a specific path to tell the function that the file is within another folder. This can be used when the file that you are trying to open is in the same directory or folder as the Python script, like this:īut if the file is within a nested folder, like this: The names.txt file is in the "data" folder We usually use a relative path, which indicates where the file is located relative to the location of the script (Python file) that is calling the open() function.įor example, the path in this function call: open("names.txt") # The relative path is "names.txt" The first parameter of the open() function is file, the absolute or relative path to the file that you are trying to work with. To learn more about them, please read this article in the documentation. There are six additional optional arguments. 💡 Tip: These are the two most commonly used arguments to call this function. One of the most important functions that you will need to use as you work with files in Python is open(), a built-in function that opens a file and allows your program to use it and work with it.
