Avoid Additional Line Spaces when reading from Text Files

I have written below code to Write and Read from a text file. When reading from the text file, I want to avoid the additional line spaces. How can that be done? ..........................................

import datetime

def buildGroceryList(grocery,count): #file = open("GroceryList.txt", 'a')

with open("GroceryList.txt", 'a') as file: #Defining it this way does not require us to explicity close the file

    current_date=datetime.datetime.today()
    if count==1:
        current_date = datetime.datetime.today()
        file.write('\n')
        file.write(datetime.datetime.strftime(current_date, '%d-%b-%Y'))

    file.write('\n')
    file.write(str(sno)+'.'+grocery)
#file.close()

def showGroceryList():

with open("GroceryList.txt") as file:  # Defining it this way does not require us to explicity close the file
    for line in file:
        print(line)

print("Build you Grocery List") print("-"*30) quit=''

sno=0 while quit=='': sno=sno+1 buildGroceryList(input("Enter a Grocery Item\n"),sno) print('-'*30) quit=input('Press Enter to Add another Item or Press any other key to Quit')

print("Your Grocery List") showGroceryList()
