Clear a Text Box within tkinter

I am trying to refresh a label in a tkinter GUI and its proving very difficult. I have tried the destroy() command and delete command e.g

def Erase():
    self.e1.delete(first=0,last=100)

I have read many posts and tkinter documentation but had no success

def retrieve_inputBoxes():
    VPNID = int(self.e1.get())
    df = pd.read_csv("Data.csv")
    output = (df[["field1", "field2", "field9"]][df["field4"]== VPNID])
    my_list1 = output["field1"].tolist()
    self.e1 = self.canvas.create_text(100 ,450 ,anchor='center', text=my_list1, font =('Helvetica', 8, 'bold'))

The data goes into the label just fine but the next time the data goes in, it overwrites the previous entry. Any help would be appreciated

The delete method needs to be called on the canvas object, not the variable self.e1. The create_text method returns an identifier, so this line:

self.e1 = self.canvas.create_text(... )

assigns that identifier to self.e1. You can use that variable to tell the delete method what to delete.

self.canvas.delete(self.e1)
