 # Exercise: Functions in python
 1. Write a function called calculate_area that takes base and height as an input and returns and area of a triangle. Equation of an area of a triangle is,
 ```
-area = (1/2)*base*height
+def calculate_area(base, height):
+    """
+    Calculate the area of a triangle given its base and height.
+
+    Args:
+    base (float): The base of the triangle.
+    height (float): The height of the triangle.
+
+    Returns:
+    float: The area of the triangle.
+    """
+    area = 0.5 * base * height
+    return area
+
 ```
 
 2. Modify above function to take third parameter shape type. It can be either "triangle" or "rectangle". Based on shape type it will calculate area. Equation of rectangle's area is,
-```
-rectangle area=length*width
+``vdef calculate_area(base, height, shape="triangle"):
+    """
+    Calculate the area of a shape given its base and height.
+
+    Args:
+    base (float): The base of the shape.
+    height (float): The height of the shape.
+    shape (str): The type of shape, can be "triangle" or "rectangle".
+
+    Returns:
+    float: The area of the shape.
+    """
+    if shape == "triangle":
+        area = 0.5 * base * height
+    elif shape == "rectangle":
+        area = base * height
+    else:
+        print("Invalid shape type. Defaulting to triangle.")
+        area = 0.5 * base * height
+    return area
+
 ```
 If no shape is supplied then it should take triangle as a default shape
 
 3. Write a function called print_pattern that takes integer number as an argument and prints following pattern if input number is 3,
 ```
-*
-**
-***
+def print_pattern(num):
+    """
+    Print a pattern based on the input number.
+
+    Args:
+    num (int): The number of lines to print in the pattern.
+    """
+    for i in range(1, num + 1):
+        for j in range(i):
+            print("*", end="")
+        print()
+
 ```
 if input is 4 then it should print
 ```
@@ -25,4 +66,4 @@ if input is 4 then it should print
 ```
 Basically number of lines it prints is equal to that number. (Hint: you need to use two for loops)
