You can use Python to read and write the contents of files.
Text files are the easiest to manipulate. Before a file can be edited, it must be opened, using the open function.
myfile = open(“filename.txt”)
You can specify the mode used to open a file by applying a second argument to the open function.
Sending “r” means open in read mode, which is the default.
Sending “w” means write mode, for rewriting the contents of a file.
Sending “a” means append mode, for adding new content to the end of the file.
Adding “b” to a mode opens it in binary mode, which is used for non-text files (such as image and sound files).
# write mode
# read mode
# binary write mode
Once a file has been opened and used, you should close it.
This is done with the close method of the file object.
file = open(“filename.txt”, “w”)
# do stuff to the file
