We can pull them apart by indexing and slicing them, and we can join them together by concatenating them. However, we cannot join strings and lists: If we use a for loop to process the elements of this string, all we can pick out are the individual characters — we don't get to choose the granularity.
The tell method of a file object tells you your current position in the open file. The seek method of a file object moves to another position in the open file. The second parameter specifies what the first one means; 0 means move to an absolute position counting from the start of the file1 means move to a relative position counting from the current positionand 2 means move to a position relative to the end of the file.
The tell method confirms that the current file position has moved. The read method reads a specified number of bytes from the open file and returns a string with the data that was read.
The optional parameter specifies the maximum number of bytes to read.
If no parameter is specified, read will read until the end of the file. You could have simply said read here, since you know exactly where you are in the file and you are, in fact, reading the last bytes.
The read data is assigned to the tagData variable, and the current position is updated based on how many bytes were read. The tell method confirms that the current position has moved. Closing Files Open files consume system resources, and depending on the file mode, other programs may not be able to access them.
In this case, the file is still open closed is False.
To close a file, call the close method of the file object. The closed attribute confirms that the file is closed.
The variable f will continue to exist until it goes out of scope or gets manually deleted. However, none of the methods that manipulate an open file will work once the file has been closed; they all raise an exception.
Calling close on a file object whose file is already closed does not raise an exception; it fails silently. This example shows how to safely open and read from a file and gracefully handle errors.Licenses.
