Left Justifying entry box next to label in Tkinter? - python-3.x

Question

So I was wondering why my entry boxes are showing in the center. Before I had the label instructions for first and last name they were aligning right. I have the labels on column 0 and the entry boxes on column 1, however they dont line up directly next to each other. If someone could help me with a very basic solution and language, I am obviously a beginner..
root = Tk()
root.title("Login Information Help")
root.configure(background='black')
root.geometry("1920x1080")
def button_click(number):
textbox.delete(0, END)
textbox.insert(0, number)
instructions = Label(root, text="Please fill in all information below to recieve student account details.", bg="black", fg="white", font="times, 20") #Create instructions line
first_name_text = Label(root, text="Enter First Name", bg="black", fg="white", font="times, 20" ) #enter first name text
inputbox1 = Entry(root, width=30, font="times, 20") #Create input boxes
last_name_text = Label(root, text="Enter Last Name", bg="black", fg="white", font="times, 20" ) #enter last name text
inputbox2 = Entry(root, width=30, font="Times, 20") #Create input boxes
button_1 = Button(root, text="Get Info", padx=45, pady=5, bg="#808080", font="times, 15", command=lambda: button_click("1")) #Define Buttons
instructions.grid(row=0, column=0) #Define Instructions variables (labels)
first_name_text.grid(row=1, column=0, pady=0, sticky=W) #position first name text
inputbox1.grid(row=1, column=1, padx=10) #Postion inputbox 1
last_name_text.grid(row=2, column=0, sticky=W) #position last name text
inputbox2.grid(row=2, column=1, padx=10, pady=10, sticky=W) #Postion inputbox 2
button_1.grid(row=3, column=0, sticky=W) #Put Buttons on Screen
root.mainloop()```

Answer 1

First row must span 2 columns.
instructions.grid(row=0, column=0, columnspan=2)
Use sticky=EW with every widget to fill the column.
Add root.columnconfigure(0, weight=0) to not expand the first column.

Answer 2

First of all this method uses pack since that is what I came up with (more explanation below) here is my code:
from tkinter import Tk, Label, Entry, Button, Frame
root = Tk()
root.title("Login Information Help")
root.configure(background='black')
root.geometry("1920x1080")
def button_click(number):
textbox.delete(0, END)
textbox.insert(0, number)
row0 = Frame(root, bg='black')
row0.pack(side='top', fill='y', anchor='nw')
row1 = Frame(root, bg='black')
row1.pack(side='top', fill='y', anchor='nw')
row2 = Frame(root, bg='black')
row2.pack(side='top', fill='y', anchor='nw')
row3 = Frame(root, bg='black')
row3.pack(side='top', fill='y', anchor='nw')
instructions = Label(row0, text="Please fill in all information below to recieve student account details.", bg="black", fg="white", font="times, 20") #Create instructions line
first_name_text = Label(row1, text="Enter First Name", bg="black", fg="white", font="times, 20" ) #enter first name text
inputbox1 = Entry(row1, width=30, font="times, 20") #Create input boxes
last_name_text = Label(row2, text="Enter Last Name", bg="black", fg="white", font="times, 20" ) #enter last name text
inputbox2 = Entry(row2, width=30, font="Times, 20") #Create input boxes
button_1 = Button(row3, text="Get Info", padx=45, pady=5, bg="#808080", font="times, 15", command=lambda: button_click("1")) #Define Buttons
instructions.pack(side='left')
first_name_text.pack(side='left')
inputbox1.pack(side='left')
last_name_text.pack(side='left')
inputbox2.pack(side='left', padx=2)
button_1.pack(side='left')
root.mainloop()
Explanation: those frames created at the top are stacked like rows, so whenever I add something to each of them using side argument in pack they get added there like columns, that padx is to make the alignment look nicer. Also I would suggest organizing the code better and start learning classes since they imo help a lot when dealing with tkinter.
So basically lets take one of the frames for example. the row1: when adding with .packand using one side (left in this case) widgets get packed in a row however it is not that easy to make them then packed in the second row so that is why there is another frame that is directly below the row1 called row2 and it gets directly packed underneath because of top side similarly as left side for widgets and those frames expand only where there are widgets (or maybe for that expansion it has to have the argument of fill, dunno rn) anyhow have a good day and experiment
