![]() Writing to a file requires a few decisions - the name of the file in which to store data and the access mode of the file. The open() method returns a file handle that represents a file object to be used to access the file for reading, writing, or appending. The common methods to operate with files are open() to open a file, seek() to set the file's current position at the given offset, and close() to close the file afterwards. This feature is a core part of the Python language, and no extra module needs to be loaded to do it properly. You can do this with the close() method or by using the with statement that automatically closes the file after writing.As pointed out in a previous article that deals with reading data from files, file handling belongs to the essential knowledge of every professional Python programmer. Write to the file using either write() or writelines() method.Open the file with the open() function.To recap, to write to a file, follow these three steps: Today you learned how to write to a file in Python. Here the result is a file called example2.txt with the following contents: This is just another test.Īs you can see, the last bits of text were successfully added to the end of the text file. # Then let's reopen the file and append some text to it: Appending means adding to the end of something.įor example: # Let's first write to a file To add text at the end of a file after the existing lines of text, use the write mode ‘a’. Next, let’s take a look at how to add text at the end of an already existing text file. Now you know how to write text to a file in Python. The writelines() function takes an iterable object, such as a list, that contains strings to be written into the opened file.įor example, let’s repeat the above example using the writelines() method: words = Īfter running this piece of code, the example.txt file looks like this: This is a test In the example.txt file the result looks like this: Thisīut in the case of multiple strings, you can use the writelines() method to write them all into a file on the same go. If you want to have each word appear on a separate line, write the line break character ‘\n’ after writing a string to the file.įor example: words = Notice how each string is written to the same line by default. It writes this argument into the opened file.įor example, let’s create a list of strings and use the write() method to write each of the strings into the file using a for loop: words = Īs a result, a file called example.txt is created with the following content: This is a test The write() method takes a string argument. Let’s see how to use these file writing methods. writelines() that writes a list of strings to the file (or any other iterable, such as a tuple or set of strings). ![]() write() that writes a single string to the text file.This file object has two useful methods for writing text to the file: The open() function returns a file object. Use the mode ‘w’ to write to the file and ‘a’ to append to a file (add text to the end of the file). mode specifies in which state you want to open the file.If no file is found, a new one is created. path_to_a_file is the path to the file you want to open.The syntax for the open() function is as follows: open(path_to_a_file, mode) In this guide, I’m going to use the with statement. Another options is to use the with statement that automatically closes the file for you. Finally, close the file using the close() method.Write text to the opened file with the write() method.Open a text file with the open() function.To write to a file in Python, use these three steps: In this guide, you are going to learn the basics of writing to a file in Python. This piece of code creates a new file called example.txt and writes “Hello World” into it. You can skip the last step by using the with statement.įor example: with open("example.txt", "w") as f: Close the file using the close() method.Write to the file using the write() method.In Python, you can write to a text file by following these three steps:
