In this video, learn how to use the tempfile module to create, write, and read temporary files. These files can be set to erase once closed, or at program termination.
- [Instructor] We can use the tempfile module…to create temporary files in Python,…but in order to use the tempfile module,…we have to import it.…And so, to import it, we'll go, import tempfile.…Now that we have access to it,…we'll go ahead and create a temporary file.…To do this, we'll create a variable, so, tempFile,…which will hold our temporary file that we create.…And then, to create the temporary file,…we'll access the module, so, tempfile.,…and then the TemporaryFile constructor there,…and that will create our temporary file.…
Now that our temporary file is stored…inside of tempfile, we'll go ahead and access tempFile,…and this is how we're going to write to the file.…And so, we'll go write, and what…we're going to want to write to this temporary file…is just a special number, and so we'll say,…Save this special number for me.…It'll be 5678, and then, 309.…And this is your special number that you're saving.…However, we're not done yet,…and that's because this write method takes a bytes object.…
And here, we have a string.…
