得到‘int’(integers)整形的判断结果。 ➶“变量”的命名规则: 1.变量名可以包含字母、数字和 下划线“_” 2.不能以数字开头 3.区分大小写 4.不能使用Python的关键字 在Python 中,具有特殊功能的标识符称为关键字。 关键字是 Python 语言已经使用的,不允许开发者自己定义和关键字相同名字的标识符。
Different integers can be used to indicate the reason why a process has failed. In the same way that you can return a value from a function in Python, the operating system expects an integer return value from a process once it exits. This is why the canonical C main() function usually ...

TypeError: list indices must be integers or slices, not str 上面的错误代码中将‘1’与1混淆了,前者是字符串,后者才是整数。可以这样改, >>> a[1] 'bbb' >>> a[1:] ['bbb', 'ccc'] 34. ValueError: substring not found 使用字符串的index函数的时候,子字符串必须在被搜索的字符串中存在。
