list1 is of empty strings. Now I've to fill this empty list with A's.

1. check if the list is empty or not

list1 = [' ',' ',' ',' ',' ',' ',' ',' ',' ']
 def check_emptystring(list1)
	for i in range(len(list1)):
		if list1[i] == ' ':
			print('list is not full')

2. make a new list "list2" as the list of indexes that are empty strings of list1 and send input A one by one. for example,after filling list1 with A's

list1 = ['A','A','','A','','','','A','']

now I've to create a new list "list2" as the indexes of empty strings in list1, so:
list2=[3,5,6,7,9]

def get_empytlist1(list1):
	list2 = []
	for i in range(len(list1)):
		if list1[i] == ' ':
			list2.append(i)
	return list2

now I've to fill at these empty indexes of list1 with A's one by one. How can i do it???

Something like this:

for index in list2:
    list1[index] = 'A'
