使用 Python 计算不同形状的面积
我们将制作一个 Python 程序来计算一些数学形状的面积。
示例:
Input: shape name = "Rectangle"
length = 10
breadth = 15
Output: Area: 150
Input: shape name = "Square"
side = 10
Output: Area: 100
进场:
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形状的区域。如果该形状不存在，我们将打印“对不起！我们找不到这个形状。”屏幕上的信息。
下面是实现:
Python 3
# 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.
