【问题描述】：

尽管我的解决方案是正确的，但当我尝试在hackerrank 上解决此问题时，我无法弄清楚为什么它会显示错误。我无法理解 STDIN 和 STDOUT。请参考我附上的图片：

import sys

def triangle(my_string = sys.stdin.readline()):
    # first parse the standard input which is in form of string
    char = []
    
    for i in str(my_string):
        char.append(i)
                
    # is all the sides of the triangle are equal it is equilateral triangle
    if char[0] == char[1] == char[2]:
        print("Equilateral")
    
    # if two sides are equal it is an Isosoleces triangle 
    elif (char[0] == char[1]) or (char[1] == char[2]) or (char[2] == char[0]):
        print("Isosceles")
    
    # if all three sides are different it is an  Noneofthese 
    else:
        print("None of these")

【问题讨论】：

你永远不会打电话给triangle
Please don't post screenshots of text。它们无法被搜索或复制，并且可用性差。相反，将代码作为文本直接粘贴到您的问题中。如果选择它并单击{} 按钮或Ctrl+K，则代码块将缩进四个空格，这将导致其呈现为代码。

标签： python stdin

【解决方案1】：

这是有效的代码。您必须将输入转换为整数。您也忽略了输入中的空格。希望对您有所帮助。

import sys

my_string = input()
# first parse teh standard input wich is in form of string
splits = my_string.split(sep=' ')
value1 = int(splits[0])
value2 = int(splits[1])
value3 = int(splits[2])

# is all the sides of the triangle are equal it is eqaulatral triangle
if value1 == value2 == value3:
    print("Equilateral")

# if two sides are eqaul it is an isoleces triangle
elif (value1 == value2) or (value2 == value3) or (value3 == value1):
    print("Isosceles")

# if all three sides are diffrent it is an  Noneofthese
else:
    print("None of these")
