Parenthesis Checker

Write a program which checks the correctness of the matching parentheses in a given Python expression using stacks. Input Python expressions are provided in an input text file. Each line contains a Python expression, as shown below.

As you notice, expressions in lines 5, 6, and 8 do not have correctly matched parenthesis and your algorithm should produce “Expression is incorrect” output. In this assignment, consider only these parentheses: ‘(’, ‘{’, ‘[’ and their closing counterparts.

x = [((1+2)*(4-3))]

nested_dict = { 'dictA': {'key_1': 'value_1'}, 'dictB': {'key_2': 'value_2'}}

print('Course: {}, Number of Students: {}]'.format('ITC547', 15))

y = ]]6

z = 14 * 8
