How to format a numeric Entry with commas (,) in Python

[IRAQSTONE]

Am using Python 3.7 when a user enters a number, he expects to see the figure displayed in the entry field with commas.

eg 3755125.70 to be displayed as 3,755,125.70. Is it possible?

[SioSio]

f = float(input())
print('{:,}'.format(f))

[IRAQSTONE]

Please is it possible to be part of the Entry options python?
eg FloatNumber=Entry(textvariable = f, ('{:,}'.format(f))

thanks

For your solution, the following code will work :

from tkinter import *
import locale
root = Tk()
 
FloatNumber = float(input('Enter no : '))
b = Entry(root, textvariable = FloatNumber, justify = RIGHT).pack()
 
def getOutput(*events):
    x = FloatNumber.get()
    y = x.replace(",",'')
    z = float(y)
    print(z)
    try:
        asd = format(z,',')
        print(asd)
    except:
        print("b")
    #Overwrite the Entrybox content using the widget's own methods
    b.delete(0, END)
    b.insert(0, asd)
 
FloatNumber.trace('w',getOutput)
root.mainloop()

import locale
>>> locale.setlocale(locale.LC_ALL, 'en_US')
'en_US'
>>> locale.format("%d", 3755125, grouping=True)
'3,755,125'

In this method, the part after the colon is the format specifier. The comma is the separator character you want,
This is equivalent of using format(num, ",d") for older versions of python.
we can use my_string = '{:,. 2f}'. format(my_number) to convert float value into commas as thousands separators.
