For this question, you will parse a string to determine if it contains only "balanced delimiters." A balanced delimiter starts with an opening character ((, [, {), ends with a matching closing character (), ], } respectively), and has only other matching delimiters in between. A balanced delimiter may contain any number of balanced delimiters.

Balanced Delimiters

array = input().strip()

lst = []

for i in range(len(array)):
    if array[i] == '(' or array[i] == '[' or array[i] == '{':
        lst.append(array[i])
    elif array[i] == ')': 
        if len(lst) != 0 and lst[len(lst)-1] == '(':
            lst.pop()
        else:
            lst.append(array[i])
    elif array[i] == ']': 
        if len(lst) != 0 and lst[len(lst)-1] == '[':
            lst.pop()
        else:
            lst.append(array[i])
    elif array[i] == '}': 
        if len(lst) != 0 and lst[len(lst)-1] == '{':
            lst.pop()
        else:
            lst.append(array[i])   
        
print (len(lst) == 0)

Extremely helpful. Thank you so much
