I created 2 programs in same dir:

helloworldprogram.py:
print("hi")

renamer.py:
import os
os.rename("helloworldprogram.py", "bananapeel.py")

And running renamer.py successfully changed "helloworldprogram.py" name to "bananapeel.py".

#Does this work?

import os

from tkinter import *
root=Tk()
f=open("main.txt","w+")
replace=f.replace("main.txt","name.txt")
f.close()
name=StringVar()
nam=Label(text="Name of customer")
txtnam=Entry(textvariable=name)

os.rename("main.txt", txtnam + ".txt")

root.mainloop()

Answer 9

Did you try txtnam.get()?

Answer 10

def rename():
os.rename("main.txt", txtnam.get())

Because the tkinter uses mainloop, you would need any tkinter widget (such as function) to call this function.

Answer 11

Should I be able to type something if I took the file openings away?:

from tkinter import *
root=Tk()

name=StringVar()
nam=Label(text="Name of customer")
txtnam=Entry(textvariable=name)
root.mainloop()

Answer 12

I couldn't type anything

Answer 13

Aren't the widgets supposed to be packed?

Answer 14

from tkinter import *

root = Tk()

name = StringVar()

nam = Label(text="Name of customer")
nam.pack()

txtnam = Entry(textvariable=name)
txtnam.pack()

root.mainloop()
