的Abaqus中止腳本命令提示符 - IndexError：-1

Question

我得到IndexError: -1

我試圖運行在命令提示符下Python腳本錯誤。當我通過Abaqus CAE運行它時，它可以工作。當我嘗試使用沒有GUI的命令提示符運行時，我得到錯誤。

我能夠完成這項工作，但我的腳本也打開了輸出數據庫。在這一步出現錯誤。

我試過Google搜索它，但我沒有得到任何更聰明。這在Python中通常意味着什麼？爲什麼我的腳本在abaqus中工作，但只通過命令提示符的一半？

謝謝！

您對IndexError三個潛在的陷阱：-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' 

      [...] 

的IndexError本身就說明，你要訪問一個列表或序列的元素，超出範圍。由於您使用的-1索引，你要訪問的列表或序列的最後一個元素，所以你訪問的任何元素，如前應檢查無空虛：

  [...] 

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

      [...] 

注and var在if子句的最後。
