How can I write to a file in Python?

How can I write to a file in Python?

You can use the built-in open() function with the mode set to 'w' for writing. Here's a simple example:

with open('example.txt', 'w') as file:
    file.write('Hello, World!')

What if I want to append to an existing file?

You can open the file in append mode by using 'a' instead of 'w'. Here's how:

with open('example.txt', 'a') as file:
    file.write('Appending this line.')

Can I write multiple lines at once?

Yes! You can use writelines() to write a list of strings. For example:

lines = ['First line.
', 'Second line.
']
with open('example.txt', 'w') as file:
    file.writelines(lines)

How do I handle exceptions when writing to a file?

You can use a try-except block to handle exceptions. Here's an example:

try:
    with open('example.txt', 'w') as file:
        file.write('Hello!')
except IOError:
    print('An error occurred while writing to the file.')
