you can practically read and write into any file.
here are a few examples.
# Write into a file
with open("text.txt") as file:
file.write("this line was written by a function")
# Read a file
with open("text.txt") as file:
file_content = file.read()
print(file_content) # this will print all the file content that has been read
Now, the file can be of any format, so go crazy with it.
