Note that before using the sys.stdout as an object to open and print the statement in the text file, a definite path of the file must be defined by the user otherwise, none of the operations can be performed on the file. Print("This text will be added to the file") In this method, we will print a statement in a text file. The form of the output can be varied, for example, it can be a prompt for input, a print statement, or just an expression. Sys.stdout is used when the user wants to display the output directly to the main console of the screen. To use the sys.stdout, the sys module needs to be imported first. The sys module is a built-in Python module that is used by the user to deal with various parts of the runtime environment in Python. Use sys.stdout to Print Output to a File in Python If the user tries to make any change in the file after calling the close() function, an error will be raised. After calling the close() function, the file cannot be read and nothing else can be written.

Note that the close() function is also used to close the file in the above code after opening it with the open(). It is always the user’s choice to either use the w operator or the a operator.Įxample: with open("randomfile.txt", "w") as external_file:Īdd_text = "This text will be added to the file" After that print() function is used to print the text in the file. In this method, first, we call the open() function to open the desired file. Use the print() Function to Print Output to a File in Python a in the code denotes that text is been added to the file. Note that open() function is used here to open the file. O.write('This text will be added to the file') Whereas a is used when the user just wants to add some text to the existing text in the file.Įxample: with open("randomfile.txt", "a") as o: w is used when the user wants to empty the file before writing anything in it. w and a are the 2 operations in this function that will write or add any text in a file. This is a built-in Python function that helps in writing or adding a specified text into a file. Use the write() Function to Print Output to a File in Python In this tutorial, we will see some methods to redirect output to a file in Python. Basically, a standard output can be printed to a file that is chosen by the user itself. In this tutorial, we shall write Python Programs to read input from user.
The standard input in most cases would be your keyboard. There is one more kind of task in file handling that can be done using python i.e redirecting output to an external file. Python input() is a builtin function used to read a string from standard input.
