![]() # Define a list containing different types of values We then use the write() method to write this string to the file. In this method, we use the join() method to concatenate all the items in the list into a single string, separated by newline characters ‘\n’. Read: Python concatenate list Method-3: Python Write List to File using the join() and the write() method Python write a list to file using the writelines method It then loops through the list and writes each item to the file using the writelines() method. ![]() ![]() The above code creates a list of mobile phone brands and then opens a file named “f1.txt” in write mode. # loop through the mobile phone list and write each item to the file # open a file named "f1.txt" in write mode In this method, we use the writelines() method to write each item in the list to the file. Read: Python list methods Method-2: Python Write List to File using the writelines() method The for loop iterates over each element in the list and writes it to the file as a string, followed by a newline character to create a new line for the next element.It uses the with statement to open the file in write mode and automatically close it after writing the data. The code writes the elements of the list my_list to a file named output.txt, with each element on a new line. # loop through the list and write each item to the file # open a file named "output.txt" in write mode We also add a newline character ‘\n’ after each item to write each item on a new line. In this method, we use a for loop to iterate through each item in the list, and use the write() method to write each item to the file. Method-1: Python Write List to File using a for loop and the write() method There are several methods for writing a list to a file in Python, including using a for loop, the writelines () method, json module, etc. One common task is writing a list to a file, which can be useful for storing data that can be read later or for sharing data with other programs. Method-5: Python Write List to File using the pickle.Method-4 Python Write List to File using the JSON module.Method-3: Python Write List to File using the join() and the write() method.Method-2: Python Write List to File using the writelines() method.Method-1: Python Write List to File using a for loop and the write() method.No close() statement is required as with open syntax automatically closes the file after executing all statements inside it.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?
