Abaqus在命令提示符- IndexError：-1中中止脚本

Question

我得到了错误IndexError: -1

我试图在命令提示符中运行Python脚本。当我在Abaqus CAE中运行它时，它就能工作了。当我尝试使用没有GUI的命令提示符运行时，就会得到错误。

我能够完成这项工作，但我的脚本也会打开输出数据库。正是在这一步出现了错误。

我试过搜索它，但我没有变得更聪明。这在Python中通常意味着什么？为什么我的脚本在abaqus中工作，但只在命令提示符中运行了一半？

谢谢!

关于IndexError有三个潜在的缺陷：-1

            [...]

            status = str(mdb.jobs[jobName].messages[-1].type)

            [...]

            for i, var in enumerate(CFNM1):
                if i == len(CFNM1) - 1:
                    maxCf1 = var[-1]
                    print str(maxCf1) + 'CFNM1 724/723'


            for i, var in enumerate(CFNM2):
                if i == len(CFNM2) - 1:
                    maxCf2 = var[-1]
                    print str(maxCf2) + 'CFNM2 722/721'

            [...]

IndexError本身表明，您正试图访问超出范围的列表或序列的一部分。由于您使用的索引为-1，所以您希望访问列表或序列的最后一个元素，因此在访问任何元素之前，应该检查是否为空，例如：

            [...]

            for i, var in enumerate(CFNM2):
                if i == len(CFNM2) - 1 and var:
                    maxCf2 = var[-1]
                    print str(maxCf2) + 'CFNM2 722/721'

            [...]

注意if子句末尾的and var。
