In my treeview (python tkinter), when I add data, I want the data to be added based on parent name (tkinter)

Question

In my TreeView I enter values manually, I would like to have them displayed like this:

Parent name1

child 1 

child 2 
   
child 3 

parent name 2 

child 1 

child 2 

The data that I enter should be added as a child to the respective parent every time I enter (the entered parent name should be checked with pre-existing parent names in treeview). Note: The data is entered into TreeView only if the failure rate is a numeric value.

#window
main = Tk()
main.title("tool")
main.geometry('1360x768')
count =0
#functions

    messagebox.showinfo("Tip", "Please Enter correct value")
def add():
    a = ie3.get()
    try:
        float(a)
        global count
        my_tree.insert(parent='', index='end',iid= count, text=ie1.get(), values=(ie2.get(), 
        ie3.get(),ie4.get(),ie5.get()))                                                                                         
        count += 1

Answer 1

First all ieX are None because it is the result of .grid(...). You need to split the line like:

ie1 = Entry(input_frame, width = 50).grid(row=0, column=1,padx=5,pady=5)

into two lines:

ie1 = Entry(input_frame, width = 50)
ie1.grid(row=0, column=1,padx=5,pady=5)

Then you need to modify add() to insert parent and child separately:

def add():
    global count
    a = ie3.get()
    try:
        float(a)
        component = ie1.get()
        if not my_tree.exists(component):
            # insert parent
            my_tree.insert(parent="", index="end", iid=component, text=component)
        # insert child
        my_tree.insert(parent=component, index='end', iid=count, values=(ie2.get(),ie3.get(),ie4.get(),ie5.get()))                                                                                         
        count += 1
    except ValueError:
        mesg()
