Python file operations, open read/write files, append text content instances, 1. After open is used to open a file, remember to call the close () method of the file object. For example, you can use the try/finally statement to ensure that the file can be closed at last. file_object = open('thefile.txt')try: all_the_text = file_object.read( )finally: file_object.c
