摘要

1. 情况1：IOException: Cannot run program "python /temporary2/plus_non_main.py": error=2, No such file or directory
2. 情况2：SyntaxError: Non-ASCII character '\xe6' in file /temporary2/plus_include_main.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

情况1：IOException: Cannot run program "python /temporary2/plus_non_main.py": error=2, No such file or directory

原因：python不认识

解决方法：

将python的执行改为绝对路径，也就是找到python.exe的所在位置

情况2：SyntaxError: Non-ASCII character '\xe6' in file /temporary2/plus_include_main.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

原因：py脚本定义的def函数中使用’’’注释快’’进行注释’’’

def plus2(a, b):
    '''# 有参数2-》网页方法3，试着传参数进去'''
    return (a + b)

解决方案：def定义的函数中使用“#单行注释”
