![]() ![]() Method 3: Write all the lines to a file at once using writelines() function If you don’t do that you’ll see all the list content in one single line. This is why I added the new line character ‘\n’ after each iteration so that the list elements are written to the file line by line. Note that the elements in the list don’t have new line character. Here’s a sample Python program: MyList = So, we’ll be using the for loop again to iterate on each element in the list and write it to the file. The write() function takes string as the argument. We are going to use the Write() function. Now let’s see another way to save list to file in Python. Method 2: Write list to file in using Write function in Python If you want to save the previous content of the file, you can open the file in append mode by using the option ‘a’ instead of ‘w’. All the previous content of the file in this mode will be overwritten. In the examples, the file has been opened in write mode with the ‘w’ option. If you use the cat command to display the content of the output file, it will be this: New YorkĪs you can see, the list elements have been written line by line in the output file. The print commands write the element to the opened file. The for loop in python iterates at each element in the list. The file output.txt is opened in writing mode. Here’s a sample Python program for your reference: MyList = ![]() The list elements will be added in a new line in the output file. The print command in Python can be used to print the content of a list to a file. Method 1: Writing a list to a file line by line in Python using print string etc using the functions mentioned here. The examples I am using here discusses writing the list to file but you can use it to write any kind of text. ![]() Writing a List to a File in PythonĪctually the methods I am going to discuss here are used for writing text to a file in Python. In this quick tutorial, I’ll show you several ways for writing a list to a file in Python. No close() statement is required as with open syntax automatically closes the file after executing all statements inside it.In an earlier scripting tip, I showed you how to execute Shell commands in Python.writelines() is used for inserting multiple strings from a list of strings to the text file simultaneously.write() method inserts a string to a single line in a text file.Python write list to file can be implemented using multiple ways.Creating, reading, opening, writing, and closing files using Python comes under File Handling.Q: Why is using the with open() method not safe?Ī: In the case of with open(), if some exception occurs while opening the file, then the code exits without closing the file. Q: How many arguments does the close() function take?Ī: The close() function doesn't take any argument. Q: How many arguments does the open() function take?Ī: The open() function takes two arguments the filename along with its complete path, and the access mode. It creates a new file if a file with the specified name is absent, else overwrites the existing file. Enroll in Scaler Topics Python certification course and level up your career. The list is looped through and all the items are written one by one.ĭon't miss the opportunity to become a certified Python specialist. The open() method opens the file in w mode. The simplest solution for Python to write the list to a file is to use a file.write() method that writes all the items from the list to a file. Which is the Best Method to Write a List to File in Python? Close the file using the close() function.The write() function adds the list of items to the text file.Using a for loop to iterate through all the items in the list. txt file function in w mode (here w signifies write). The list is iterated using a loop, and during every iteration, the write() method writes an item from the list to the file along with a newline character. Close the file after completing the write operation. ![]() Write current items from the list into the text file.A list in Python can be written in a file in various ways. The write() or writelines() method helps Python write lists to files. Python writes list to file and saves the data contained in the list to a text file. Elements in a list may be unique or duplicates and are identified by a unique position called an index. The List in Python is a built-in data structure that stores heterogeneous or homogeneous data in a sequential form. ![]()
