「for循環」（pyvmomi）中的python3.4縮進錯誤

Question

試圖在循環中調用python3.4類方法。 但是得到這個「TabError: inconsistent use of tabs and spaces in indentation」

我在「vim」和「gedit/sublime」中查看了代碼，並且它們沒有顯示明顯的錯誤。

它不一定是縮進，但其他一些錯誤？

謝謝。

## Create a view

此代碼有縮進問題。

變化

for child in children: if child.summary.guest is not None: try: tools_version = child.summary.guest.toolsStatus osFam = child.summary.guest.guestId print("VM: {}, VMware-tools: {}".format(child.name, tools_version)) print("VM: {}, OS Fam: {}".format(child.name, osFam)) except: print("Vmware-tools: None")

要 for child in children: if child.summary.guest is not None: try: tools_version = child.summary.guest.toolsStatus osFam = child.summary.guest.guestId print("VM: {}, VMware-tools: {}".format(child.name, tools_version)) print("VM: {}, OS Fam: {}".format(child.name, osFam)) except: print("Vmware-tools: None")

如果這是你的整個.py文件，錯誤是在線路114和116 不要複製粘貼此代碼，因爲有可能是太多的空白。只需從我提到的代碼中縮進代碼即可。

編輯：在vim或gedit或其他文本編輯器中編寫代碼並不是一個好習慣。看看Pycharm :)
