我收到错误IndexError: -1
我正在尝试在命令提示符下运行Python脚本。当我通过Abaqus CAE运行时，它可以工作。当我尝试使用没有GUI的命令提示符运行时，我得到了错误。
我能够完成这项工作，但我的脚本也会打开输出数据库。出现此步骤时出现错误。
我试过谷歌搜索它，但我没有更聪明。这在Python中通常意味着什么？为什么我的脚本在abaqus中运行，但只在命令提示符的一半处？
谢谢！

IndexError 本身表示您正在尝试访问超出范围的列表或序列的元素。由于您使用的索引为 -1 ，因此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检查是否为空，例如：
[...]

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

请注意if子句末尾的and var。
