How do I open a file in Python and keep writing to it without overwriting the existing content?

To open a file for writing in Python and continue writing to it without overwriting the existing content 1, you need to use the "a" mode instead of the standard "w" mode. The "a" mode stands for “append mode”, which will allow you to continue writing to the end of the file instead of starting from the beginning.

Here’s an example code snippet to illustrate how to open a file in "a" mode and write to it:

with open("myfile.txt", "a") as myfile:
    myfile.write("This is some new text that will be added to the end of the file!")

In this example, "myfile.txt" is the name of the file you want to open, and "a" is the mode you want to open it in. The "with open" statement opens the file and ensures that it’s closed properly when you’re done writing to it. The write() method writes the new text to the end of the file.

Using "a" mode ensures that any existing content in the file will be preserved, and that your new text will be added to the end of the file without overwriting anything.
