Sure, I can explain it to you.
To write a file in Python 3.10, we use the built-in open() function in write mode ('w'). Below is a simple example to write a text file in Python:
# Open the file in write mode
file = open('example.txt', 'w')
# Write text to the file
file.write('Hello, world!\n')
file.write('Welcome to Python\n')
# Close the file
file.close()
In this code, we opened and created the file example.txt in write mode using the open() function. We then used the .write() method to write text to the file.
Note that the .write() method does not add a newline character by default. So, we manually added a newline character (\n) at the end of the first line.
Finally, after writing the text, we closed the file using the .close() method.
You can now check the contents of the file by opening example.txt.
Hope, it helps. Let me know if you have any further questions.
