WEBVTT 00:00.000 --> 00:05.000 Building program and debugging. 00:05.000 --> 00:09.000 We'll be understanding how to build a number guessing game. 00:09.000 --> 00:13.000 Debug the program. Let's understand what we are trying to do. 00:13.000 --> 00:16.000 The program picks a secret number between 1 to 20. 00:16.000 --> 00:23.000 After each guess, the program will tell you if it's too high, too low, or correct. 00:23.000 --> 00:26.000 You have limited chances to guess. 00:26.000 --> 00:31.000 Let's start. Generate a random number. Import random. 00:31.000 --> 00:42.000 We have imported and random module. The random module in Python is a built-in library that provides functions to generate random numbers and make random selections. 00:42.000 --> 00:52.000 Type, secret, number equals to random dot. Random open parenthesis, 1 comma 20 close parenthesis. 00:52.000 --> 01:00.000 The random function from the random module generates a random number between two specified values, including both. 01:00.000 --> 01:04.000 It sets a new secret number each time you start the game. 01:04.000 --> 01:09.000 Set the player's attempts to 5. Attempts equals 5. 01:09.000 --> 01:13.000 We will show the game title and add instructions to the player. 01:13.000 --> 01:18.000 Print. Guest the secret number game, backslash n. 01:18.000 --> 01:24.000 The backslash n tells Python to leave a blank line after this sentence. 01:24.000 --> 01:27.000 Print. Keep entering number until you guess it correctly. 01:27.000 --> 01:30.000 Print. Line. Backslash n. 01:30.000 --> 01:36.000 Create a loop for guessing for space underscore and range. Attempts. 01:36.000 --> 01:42.000 Guest equals to int. Input. Guest the number between 1 to 20. 01:42.000 --> 01:51.000 As we are stored the information in the form of a string, we need to add int, function, so that when the player enters the number, it takes it as an integer. 01:51.000 --> 01:54.000 Then, run the loop to check if it works correctly. 01:54.000 --> 02:00.000 Debug the program. Python has shown an error online eight. Let's fix it. 02:00.000 --> 02:08.000 If we check the code, we will understand that we have not closed the quotation marks. Add the end quotation mark. 02:09.000 --> 02:14.000 Now run the program. We will see the text printed. Check the player's guess. 02:14.000 --> 02:23.000 You will use conditionals, if, else, if, and else to check whether the guess is correct, too high or too low. 02:23.000 --> 02:32.000 We will add a if condition, if guess equals secret number. Print. Congratulations. You've guessed the correct number. 02:32.000 --> 02:43.000 Break. The break statement stops the loop at that moment. When the player guesses the secret number correctly, there's no need to continue asking for guesses. 02:43.000 --> 02:56.000 We will add an else if and else condition. Lif. Guest is greater than secret number. Print. Too high. Else. Print. Too low. 02:56.000 --> 03:02.000 We have nearly completed the program. Let's run it to check if it works. Debug the program. 03:02.000 --> 03:11.000 We will only get the most recent error on the console, which is online nine. Syntax error. Expected. 03:11.000 --> 03:16.000 We have not added the colon after secret number. We will add the colon. 03:16.000 --> 03:22.000 The colon helps the program understand that the following indented lines are part of the if statement. 03:23.000 --> 03:31.000 Click on run to check whether the code is working. There is one more error online, 12, which needs to be fixed. 03:31.000 --> 03:38.000 In the alif condition, if the player's guess is greater than secret number, it should print too high. 03:38.000 --> 03:45.000 But we haven't included the greater than sign in the statement. Add greater than sign. 03:46.000 --> 03:52.000 We will check if the code runs properly. Now the code is executed properly. End the game. 03:52.000 --> 04:03.000 To end the game, we will add a statement. Else. Print. F. Sorry. You've run out of attempts. The correct number was secret number. 04:03.000 --> 04:11.000 It is important to add F, formatted string, so we get the secret number printed in the console after all incorrect attempts. 04:12.000 --> 04:21.000 Let's run a check whether we can find the secret number. 04:21.000 --> 04:31.000 Congratulations on building your first number guessing game.
