isinstance不输出任何东西
使用isinstance时，我的代码不输出任何内容。 这在代码的最后显示。 我尝试inputyear 1和tla_2=1 ，没有输出发生。 我的isinstance声明是错误的。 我是否循环不正确？
output = 'From Bus #: {}\tTo Bus #: {}\tTo Bus #: {}\t Area Station: {}\t VMIN: {} pu\tVMAX: {} pu\t' print(output.format(from_, to,name2, min_value, max_value,last_bus))

csv.writer能够将任何数据（整数，浮点数，string…）写入csv 。 但csv.reader不执行反转操作。
last_bus是直接来自csv.reader迭代器的数据。 所以它必须是一个string。
所以，你的isinstance方法不能返回True 。
有几种方法来检查一个string是否实际上是一个整数。 我不会在这里解释他们，这将是很多已经回答的问题是多余的，但检查这个问答（有其他问答的链接）来实现你的select之一： 如何检查一个string是否有一个数值在Python中？
一旦你确定这个string持有一个整数，只需要int(last_bus)转换为整数。
好，所以我做了你所说的。 它输出正确，但不输出到psspy函数。
