python3.4 "for loop" 中的缩进错误 (pyvmomi)

Question

试图在循环中调用 python3.4 class 方法。但是得到这个“TabError: inconsistent use of tabs and spaces in indentation”

我查看了 "vim" 和 "gedit/sublime" 中的代码，它们没有显示明显的错误。

难道不是缩进而是其他错误？

谢谢。

这段代码有缩进问题。

改变

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")

到 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")

如果那是你的整个 .py 文件，错误在第 114 和 116 行。不要复制粘贴此代码，因为可能会有太多空格。只需缩进我提到的行中的代码即可。

编辑：在 vim 或 gedit 或其他文本编辑器中编写代码不是一个好习惯。看看Pycharm :)
