unexpected EOF while parsing

[whatloop]

On executing the script the python prompts for number until the user enters null as an input

def main():
        total = 0 
        number = input('Enter a number : ')
        while number != '':
                total += int(number)
                number = input('Enter a number : ')
        print('Sum of all input number is : ',total)
if __name__=='__main__':
        main()

Error

You never break out of the loop.
In a function can use return as return always get value out and exit function.
indentation is 4-space not 8.

def main():
    total = 0
    number = input('Enter a number : ')
    while number != '':
        total += int(number)
        number = input('Enter a number : ')
    return f'Sum of all input number is : {total}'

if __name__=='__main__':
    print(main())

Besides ... get a glance to Python powerful!

Output:
C:\Training>python somma.py
Enter a number : 1234567890123456789012345678901234567890123456789012345678901234567890
Enter a number : 1
Enter a number :
Sum of all input numbers is : 1234567890123456789012345678901234567890123456789012345678901234567891
