separatedWord = list(input_word)
you can typecast a string as list
try this code:
from tkinter import *
class MyEntry(Entry):
def __init__(self, root, textvariable):
Entry.__init__(self, master=root, textvariable=textvariable)
#binding your trace handler to your textvariable
textvariable.trace_add("write", self._traceHandler)
#or just use this handler
def _traceHandler(self, x, y, z):
# code block
print(self.getSeparatedWord())
#you can call this
def getSeparatedWord(self):
value = self.get()
return list(value)
root = Tk()
my_textvar = StringVar()
my_entry = MyEntry(root, my_textvar)
my_entry.pack()
root.mainloop()
