With Tcl/Tk, you can generate widgets "on the fly" during program execution, without having to explicitly create them in your code.  i.e., something like:



for {set i 0} {$i <= 5} {incr i} {
    label .myLabel_$i -text "this is label myLabel_$i"
    pack .myLabel_$i 

}



for x in xrange(5):    Label(root, text="This is label %d" %x).pack()
will generate the labels. You can't put the variable names in the local namespace without some tricksy methods. You could, however, have a dict labels and just do


labels[x] = Label(root, text="blah")labels[x].pack()
