+Code Explanation:
+A dictionary named items is created to store product names and their corresponding prices.
+Example: "apple": 5 means apple costs 5 units.
+
+one variable is initialized:
+
+total_price to keep track of the overall bill.
+
+
+A menu is printed that shows the user what number to press for each item or to generate the final bill.
+
+A while True loop is started, meaning it will keep running until the user explicitly chooses to stop (by selecting "6" for the bill).
+
+Inside the loop:
+
+The user is asked to enter a number (1–6).
+
+Depending on their input:
+
+If they enter 1–5, the corresponding item is "added to the cart" and its price is added to the total_price.
+
+If they enter 6, the total price is printed and the loop breaks (ends).
+
+If they enter something outside 1–6, a warning message is shown.
+
+The try-except block is used to catch errors if the user enters something that's not a number (like a letter or symbol).
+In that case, it simply shows: "enter only digits".
