Automating WinSCP file transfer in Python using using pywinauto

I am trying to automate a file transfer process in WinSCP using Python and pywinauto. I am currently sending keyboard keys of Ctrl+ to open a directory and search a path, but when I run my program, it will not open the open directory window. Please help!

kb.send_keys("^0")

app1 = Application().connect(title=u'Open directory')
win1 = app1.TOpenDirectoryDialog

src_folder = "/data/cog/deployments"
win1[u'Edit'].type_keys(src_folder)
win1.OK.click()

This is the error code I am getting:

Traceback (most recent call last):

    app1 = Application().connect(title=u'Open directory')
