You can write a list to a file in Python using the 'writelines()' method or by iterating through the list and writing each item individually. For example, you can use the following code: with open('filename.txt', 'w') as f: f.writelines('%s ' % item for item in my_list).
You can use 'w' for writing (which overwrites the file if it exists), 'a' for appending (which adds to the end of the file), and 'x' for exclusive creation (which fails if the file already exists).
Yes, but you need to convert non-string items to strings before writing them to a file. You can do this using the 'str()' function or by using a list comprehension to convert the items.
You can achieve this by adding a newline character (' ') after each item when writing to the file. For example, you can modify the code to: f.writelines('%s ' % item for item in my_list).
If you encounter an error, check for common issues such as file permissions, whether the file is open in another program, or if the path to the file is correct. You can also use a try-except block to handle exceptions gracefully.
