The syntax to declare a function is: def function_name(arguments): User-defined functions - We can create our own functions based on our requirements.Standard library functions - These are built-in functions in Python that are available to use.There are two types of function in Python programming: You can create two functions to solve this problem:ĭividing a complex problem into smaller chunks makes our program easy to understand and reuse. Suppose, you need to create a program to create a circle and color it. An example of this approach has been provided above.A function is a block of code that performs a specific task.

Using a context manager (with statement) is generally recommended as it automatically closes the file once the block exits. Writing a list to a file in Python can be done by opening the file in write mode, converting the list items into a string, writing that string to the file and then closing it. With open('list_output.txt', 'w') as file: Using a context manager (with statement) is generally a better approach because it automatically closes the file once the block exits: This will create a file named `list_output.txt` with the following content: # You can customize the separator, in this case, I'm using a newline 'n' to separate list items # Convert the list items into a string and write the list data to the file # This is your list of data you want to save in a fileĭata_list = Close the file using the `close` function. Write the string to the file using the `write` function.Ĥ. Use a loop or a join function to convert the list items into a string.ģ. Open a file in write mode using the `open` function with ‘w’ as the second argument.Ģ. To write a list to a file in Python, you can use the following approach.ġ. We will also look at how to use context managers (with statement) for better control over files.

In this blog post, we will discuss the approach of using `open`, `write` and `close` functions for writing data from a list into a file. Writing a list to a file in Python is an easy task.
