In contrast, using the binary mode "b" when using the open function returns bytes. Binary mode is typically used when handling non-text files such as images and executables. Here are few examples of using these access modes in Python:. Besides having a cleaner syntax, the "with" statement also makes exception handling easier when working with file objects.
It is considered best practice to use the with statement when working with files whenever applicable. A significant advantage that using the with statement offers is that it automatically closes any files you've opened after the operation is complete. Thus, you don't have to worry about closing the file and cleaning up after performing any operation on a file.
To read a file using the with statement, you would write the following lines of code:. When the second line of code runs, all of the data stored in "example. If you wanted to write data to the same file, you would run the following code:.
Reading a file in Python is straightforward — you must use the 'r' parameter or not mention a parameter at all since it is the default access mode. That said, there are other ways to read data from a file in Python. For example, you could use the read size method built into Python to read the specified size of data.
If you do not specify the size parameter, the method will read the file until its end. Let's assume that "example. This file has two lines. To read the file using the read method, you would use the following code:. In the example above, the read method returns the new line character when the line ends. Furthermore, once the end of the file is reached, it returns an empty string. It is possible to change the cursor position regardless of what access mode you're using with the help of the seek method.
To check the current position of the cursor, you can use the tell function. Install Python 3. Open IDLE. Click File. Click Open. Select your Python file and click Open. Did this summary help you?

Justin: "run on any computer" is not happening. Not all processors use the same instruction set. At most one processor family will be able to run your program without needing special translation runtime support files, and in order to do much of anything useful, you need OS-specific code as well. Running on more than one system will always need a system-specific runtime helper.
