+# Conditional Statements in Python
 
 Conditional statements in Python are used to make decisions in your code. They allow you to execute certain blocks of code based on whether a condition is `True` or `False`.

 The basic syntax for a conditional statement is:
 
 ```python
+
 if condition:
  # Code to execute if the condition is True
 elif another_condition:
  # Code to execute if the second condition is True
 else:
  # Code to execute if none of the above conditions are True
+```
+## Practice Questions: Conditional Statements in Python
+
+### 1. Basic Condition
+Write a program that checks if a number is positive, negative, or zero. Print an appropriate message based on the result.
+
+### 2. Even or Odd
+Write a program that checks if a given number is even or odd. Print "Even" if the number is even, and "Odd" if the number is odd.
+
+### 3. Grading System

+- 90 to 100: A
+- 80 to 89: B
+- 70 to 79: C
+- 60 to 69: D
+- Below 60: F
+

+- Child (0-12)
+- Teenager (13-19)
+- Adult (20-64)
+- Senior (65 and above)
+
