Find and fix the error in the if-else statement.
 
 
### Code Explanation The code snippet provided in the image is as follows: ```python 1 user_num = int(input()) # Program will be tested with values: 1, 2, 3, 4. 2 3 if user_num < 0 and user_num < 4: 4 print('Num is equal to two') 5 else: 6 print('Num is not two') ``` ### Code Analysis - **Line 1:** The program takes an integer input from the user and assigns it to the variable `user_num`. - **Line 3:** An `if` statement checks if `user_num` is less than 0 and less than 4. - **Line 4:** If the condition is true, it prints "Num is equal to two". - **Line 6:** If the condition is false, it prints "Num is not two". ### Logical Error The intention seems to be checking if `user_num` is equal to 2, but the condition `user_num < 0 and user_num < 4` is incorrect. The `if` statement should check: ```python if user_num == 2: ``` ### User Interface - A user inputs a number into a text box labeled with a background showing a value (1 in the example). - There are two buttons labeled "Check" and "Try again". - An error message indicates: "The if statement has to check if `user_num` is not 2." This setup suggests it is part of an educational platform, likely testing or teaching conditional statements in Python.

### Educational Content: Understanding Program Output Comparisons This illustration provides a comparison between expected and actual outputs in a basic programming exercise. Below is the detailed transcription of the comparison results: --- 1. **Compare Output** - **Input:** `1` - **Your Output:** - Correct: "Num is not two" 2. **Compare Output** - **Input:** `2` - **Your Output:** - Incorrect: "Num is **not** two" - **Expected Output:** - "Num is **equal to** two" - **Explanation:** There is a discrepancy between the expected and actual output for the input `2`. The expected output indicates equality with the number two, while the actual output incorrectly suggests inequality. 3. **Compare Output** - **Input:** `3` - **Your Output:** - Correct: "Num is not two" 4. **Compare Output** - **Input:** `4` - **Your Output:** - Correct: "Num is not two" --- ### Graphs/Diagrams There are no graphs or diagrams in the provided image. The content solely includes text comparisons between expected and actual outputs, highlighting discrepancies when present.
