Python 程序：检查三角形是否有效

编写一个 Python 程序，使用用户指定的角度来检查三角形是否有效。请记住，任何三角形只要三条角之和等于 180 度，则该三角形就是有效的。

Python 程序：检查三角形是否有效 示例 1

这个 Python 程序帮助用户输入三角形的所有角度。接下来，我们使用 If Else 语句 来检查给定角度的总和是否等于 180。如果为 True，则打印语句打印“这是一个有效三角形”。否则，Python 程序打印“这是一个无效三角形”。

# Python Program to check Triangle is Valid or Not

a = int(input('Please Enter the First Angle of a Triangle: '))
b = int(input('Please Enter the Second Angle of a Triangle: '))
c = int(input('Please Enter the Third Angle of a Triangle: '))

# checking Triangle is Valid or Not
total = a + b + c

if total == 180:
    print("\nThis is a Valid Triangle")
else:
    print("\nThis is an Invalid Triangle")

Python 程序：验证三角形是否有效 示例 2

在上面的 Python 示例中，我们忘了检查是否有任何角度为零。因此，我们使用了 逻辑 AND 运算符来确保所有角度都大于 0。

a = int(input('Please Enter the First Angle of a Triangle: '))
b = int(input('Please Enter the Second Angle of a Triangle: '))
c = int(input('Please Enter the Third Angle of a Triangle: '))

# checking Triangle is Valid or Not
total = a + b + c

if (total == 180 and a != 0 and b != 0 and c != 0):
    print("\nThis is a Valid Triangle")
else:
    print("\nThis is an Invalid Triangle")

Please Enter the First Angle of a Triangle: 70
Please Enter the Second Angle of a Triangle: 70
Please Enter the Third Angle of a Triangle: 40

This is a Valid Triangle

Please Enter the First Angle of a Triangle: 90
Please Enter the Second Angle of a Triangle: 90
Please Enter the Third Angle of a Triangle: 0
