Try this out

from tkinter import *

root = Tk()
root.geometry("800x800")

def callback(event):           
    msg = e1.get()
    print(msg)

Label(root, text="Student Name").place(x=140, y=40)

e1 = Entry(root)
e1.place(x=140, y=10)
e1.bind('<Return>',callback) #<Return> is equivalent to your Enter key

root.mainloop()

When you click on Enter key, on the entry widget, then the function gets called and the output will be printed out. I also removed the global as it makes no sense to use it in outside functions.

Hope it helped you out.

Cheers
