使用Python计算不同形状的面积

我们将编写一个Python程序来计算一些数学形状的面积。

例子：

Input: shape name = "Rectangle"
       length = 10
       breadth = 15
Output: Area: 150

Input: shape name = "Square"
       side = 10
Output: Area: 100

方法：

在这个程序中，我们将要求用户输入形状的名称。如果它存在于我们的程序中，那么我们将继续根据它们各自的公式找到输入的形状的区域。如果该形状不存在，那么我们将打印“对不起！我们找不到这个形状。”屏幕上的消息。

下面是实现：

Python3

# define a function for calculating
# the area of a shapes
def calculate_area(name):\
   
  # converting all characters
  # into lower cases
  name = name.lower()
   
  # check for the conditions
  if name == "rectangle":
    l = int(input("Enter rectangle's length: "))
    b = int(input("Enter rectangle's breadth: "))
     
    # calculate area of rectangle
    rect_area = l * b
    print(f"The area of rectangle is
          {rect_area}.")
   
  elif name == "square":
    s = int(input("Enter square's side length: "))
       
    # calculate area of square
    sqt_area = s * s
    print(f"The area of square is
          {sqt_area}.")
 
  elif name == "triangle":
    h = int(input("Enter triangle's height length: "))
    b = int(input("Enter triangle's breadth length: "))
       
    # calculate area of triangle
    tri_area = 0.5 * b * h
    print(f"The area of triangle is
          {tri_area}.")
 
  elif name == "circle":
    r = int(input("Enter circle's radius length: "))
    pi = 3.14
         
    # calculate area of circle
    circ_area = pi * r * r
    print(f"The area of triangle is
          {circ_area}.")
         
  elif name == 'parallelogram':
    b = int(input("Enter parallelogram's base length: "))
    h = int(input("Enter parallelogram's height length: "))
     
    # calculate area of parallelogram
    para_area = b * h
    print(f"The area of parallelogram is
          {para_area}.")
     
  else:
    print("Sorry! This shape is not available")
 
# driver code
if __name__ == "__main__" :
   
  print("Calculate Shape Area")
  shape_name = input("Enter the name of shape whose area you want to find: ")
   
  # function calling
  calculate_area(shape_name)

输出：

Calculate Shape Area
Enter the name of shape whose area you want to find: rectangle
Enter rectangle's length: 10
Enter rectangle's breadth: 15
The area of rectangle is 150.
