How to Fix Labels and Entries Inside Tab

I write labels and entries inside notebook tab, however it doesn't lined up vertically. Instead, it's horizontal.

I tried using grid, but it doesn't work because:

_tkinter.TclError: cannot use geometry manager grid inside .!notebook.!frame which already has slaves managed by pack

from tkinter import *
from tkinter import ttk

class View:

    def __init__(self, root):

        # Define software title
        root.title("Plotting Management System")

        # Define software's width and height
        root.geometry("800x600")

        # Define label
        L0 = Label(root, text="Plotting Management System", font="Helvetica 24 bold")
        L0.grid(row=0)
        L0.pack(anchor="nw")

        tab_parent = ttk.Notebook(root)

        tab0 = ttk.Frame(tab_parent)

        tree0 = ttk.Treeview(tab0)
        tree0["columns"] = ("one", "two", "three", "four")
        tree0.heading("#0", text="Kode Dosen", anchor="w")
        tree0.column("#0", minwidth=0, width=100, stretch=NO)
        tree0.heading("one", text="Nama Dosen", anchor="w")
        tree0.column("one", minwidth=0, width=300, stretch=NO)
        tree0.heading("two", text="JFA", anchor="w")
        tree0.column("two", minwidth=0, width=100, stretch=NO)
        tree0.heading("three", text="Prodi", anchor="w")
        tree0.column("three", minwidth=0, width=80, stretch=NO)
        tree0.heading("four", text="KK", anchor="w")
        tree0.column("four", minwidth=0, width=80, stretch=NO)
        tree0.pack(anchor="w")

        L1 = Label(tab0, text="Kode Dosen")
        L1.pack(side="left", anchor="w")
        E1 = Entry(tab0, width=50)
        E1.pack(side="left")

        L2 = Label(tab0, text="Nama Dosen")
        L2.pack(side="left", anchor="w")
        E2 = Entry(tab0, width=50)
        E2.pack(side="left")

        L3 = Label(tab0, text="JFA")
        L3.pack(side="left", anchor="w")
        E3 = Entry(tab0, width=50)
        E3.pack(side="left")

        L4 = Label(tab0, text="Prodi")
        L4.pack(side="left", anchor="w")
        E4 = Entry(tab0, width=50)
        E4.pack(side="left")

        L5 = Label(tab0, text="KK")
        L5.pack(side="left", anchor="w")
        E5 = Entry(tab0, width=50)
        E5.pack(side="left")

        tab_parent.add(tab0, text="Data Dosen")
        tab_parent.pack(fill="both")

if __name__ == "__main__":
    root = Tk()
    gui = View(root)
    root.mainloop()

I want them to lined up vertically, not horizontally.

Wanted Result:

Label 1 | Entry 1

Label 2 | Entry 2

Label 3 | Entry 3

Actual Result:

Label 1 | Entry 1 | Label 2 | Entry 2 | ...

As the error shows, you cannot mix grid and pack with the same parent. But you can add another frame using pack, and have your Label and Entry widgets using grid as the geometry manager inside that frame.

class View:
    def __init__(self, root):
        ...
        label_frame = ttk.Frame(tab0)
        label_frame.pack(anchor="w")

        L1 = Label(label_frame, text="Kode Dosen")
        L1.grid(row=0,column=0)
        E1 = Entry(label_frame, width=50)
        E1.grid(row=0,column=1)
        ...

Also I recommend using a for loop to create your Label/Entry pairs. It can save you from repetitive codes:

for num, i in enumerate(("Kode Dosen","Nama Dosen","JFA","Prodi","KK")):
    a = Label(label_frame, text=i)
    a.grid(row=num, column=0)
    b = Entry(label_frame, width=50)
    b.grid(row=num,column=1)

If you need the value of the Entry, you can append them to a list during the loop.
