Sure, let's create an informative tutorial on evaluating postfix expressions in Python.
Postfix notation, also known as Reverse Polish Notation (RPN), is a mathematical notation in which every operator follows all of its operands. For example, the infix expression 3 + 4 * 5 would be written in postfix notation as 3 4 5 * +.
To evaluate a postfix expression, we can use a stack data structure. The algorithm involves scanning the expression from left to right and performing the following steps:
Let's implement this algorithm in Python.
In this example, the evaluate_postfix function takes a postfix expression as a string and returns the result of the evaluation.
Let's take the postfix expression "34+5*" as an example:
Feel free to modify the postfix_expression variable with other postfix expressions to test the function.
