[FIXED] how to convert strings to float

Issue

code image

Hello, I am trying to write a code that takes in a number of inputs and outputs the graph that they form, (ex. quadratic equations, and cubic). In the image linked I am trying to get in the inputs as entrys from a window that I have created using Tkinter, however, when I go to work with the values I need to convert them into float numbers, however, I don’t know how I can it.

Can someone help me, please?

Solution

here there is no function 'type' instead use 'delete' and 'insert' the '0' represents the cursor position (i.e in starting) and 'end' denotes till end

from tkinter import *
root=Tk() 
def conversion():
    global a
    global b
    global c
    global d
    for i in (a,b,c,d):
        k=float(i.get())
        i.delete(0,'end')
        i.insert(0,k)
a=Entry(root,text='3')
a. pack() 
b=Entry(root)
b.pack() 
c=Entry(root)
c.pack() 
d=Entry(root)
d.pack() 
buttonl=Button(root, text="press",command=conversion)
buttonl.pack() 
root .mainloop()
