As shown below:
out = ('adb shell pm list packages')
top = ()
('List of package names')
('%dx%d' % (400, 1200)) # Set window size
t = Text(top, width=400, height=900)
('1.0', "{}".format(out[1]))
# Insert text in quotes to bring up "1.0" This is the coordinates of the inserted text, and the dot between 1 and 0, not the comma, remember.
# wraplength: Specify how many units to start the wrapping.
# justify: Specify alignment for multiple lines
# Example: Label(top, text='View all package names on current phone: ',wraplength = 80,justify = 'left').grid(row=1,stick=W, pady=10)
