File data can also be uploaded through FTP. As with downloading, there are two basic functions for uploading: storbinary() and storlines(). Both take a command to run, and a file-like object to transmit. The storbinary() function will call the read() method repeatedly on that object until its content is exhausted, while storlines(), by contrast, calls the readline() method. Unlike the corresponding download functions, these methods do not require you to provide a callable function of your own. (But you could, of course, pass a file-like object of your own crafting whose read() or readline() method computes the outgoing data as the transmission proceeds!) Listing 17 5 shows how to upload a file in binary mode. Listing 17 5. Binary Upload #!/usr/bin/env python # Binary download - 17 - binaryul.py from ftplib import FTP import sys, getpass, os.path if len(sys.argv) != 5: print "usage: %s <host> <username> <localfile> <remotedir>" % ( sys.argv[0]) exit(2) host, username, localfile, remotedir = sys.argv[1:] password = getpass.getpass( "Enter password for %s on %s: " % (username, host))

Now select the four buttons and the spring, and then apply a vertical layout so that you get the form shown in Figure 2-15. You can select multiple items by clicking and holding the Shift key or by dragging a box containing the items that you want to select. Notice that you do not want to add the layout from the widget box. Instead, select the widgets that you want inside the layout and click the vertical layout button in the toolbar shown in Figure 2-14. The buttons are the following (from left to right): Apply horizontal layout places the widgets in horizontal row. Apply vertical layout places the widgets in a vertical row. Horizontal splitter places the widgets in a horizontal row, but also enables the user to adjust the size of the widgets. Vertical splitter places the widgets in a vertical row, but also enables the user to adjust the size of the widgets. Apply grid layout places the widgets in a stretchable grid. Break layout removes any current layout. Adjust size adjusts the size of the current layout so that the contained widgets fit. Try holding the pointer over the toolbar buttons to find the one with the tooltip Lay Out Vertically, which is the one you want.

f = FTP(host) f.login(username, password) f.cwd(remotedir) fd = open(localfile, 'rb') f.storbinary('STOR %s' % os.path.basename(localfile), fd) fd.close() f.quit() This program looks quite similar to our earlier efforts. Since most anonymous FTP sites do not permit file uploading, you will have to find a server somewhere to test it against; I simply installed the old, venerable ftpd on my laptop for a few minutes and ran the test like this: $ python binaryul.py localhost brandon test.txt /tmp I entered my password at the prompt (brandon is my username on this machine). When the program finished, I checked and, sure enough, a copy of the test.txt file was now sitting in /tmp. Remember not to try this over a network to another machine, since FTP does not encrypt or protect your password! You can modify this program to upload a file in ASCII mode by simply changing storbinary() to storlines().

Now that you ve got your Upcoming block, complete with API key, added to the design surface, it s time to configure the Virtual Earth block s properties. This block (see Figure 4-15) has four operations: addPushpin: Adds a pushpin to the map at a specific location setMapView: Sets the viewable area of the map drawLine: Draws a line from point to point on the map deleteAllPushpins: Removes all pushpins from the map

Figure 2-15. All widgets in a vertical layout You can find the list widget in the group item widgets in the widget box. Place it on the form in the middle of the free space. Then click on a free spot on the form, which selects the actual form. You can see that you have selected the actual form by looking at the Object

Just like the download process had a complicated raw version, it is also possible to upload files by hand using ntransfercmd(), as shown in Listing 17 6. Listing 17 6. Uploading Files a Block at a Time #!/usr/bin/env python # Advanced binary upload - 17 - advbinaryul.py from ftplib import FTP import sys, getpass, os.path BLOCKSIZE = 8192 # chunk size to read and transmit: 8 kB

Inspector. When the dialog is chosen, you have the right selection. Now apply a grid layout by clicking the appropriate button in the toolbar. Applying a layout when having selected a widget containing other widgets applies that layout to the form (layout is an attribute of the parent widget, not the children within it). Figure 2-16 shows the form after the list widget has been added, and Figure 2-17 shows the form after the layout has been applied.
