Python IndentationError: unindent does not match any outer indentation level
提问by Daniel
I am trying to update a dictionary value in Python. I'm trying to update a value in the dict by subtracting 3 from the value.
我正在尝试更新 Python 中的字典值。我试图通过从值中减去 3 来更新字典中的值。
if buildings == 1:
workpower -= 3
if workpower >= 0:
farmplace1 = int(input("where do you want it?"))
farmplace2 = int(input("where do you want it?"))
board[farmplace1][farmplace2] = "F"
my_dict['d'] -= 3;
I get the following error
我收到以下错误
IndentationError: unindent does not match any outer indentation level
What is wrong with the code?
代码有什么问题？

Change your indentation and ensure it's consistent ( just use spaces or just use tabs, don't mix both ):
更改缩进并确保其一致（只需使用空格或仅使用制表符，不要混合使用）：
if buildings == 1:
workpower -= 3
if workpower >= 0:
farmplace1 = int(input("where do you want it?"))
farmplace2 = int(input("where do you want it?"))
board[farmplace1][farmplace2] = "F"
my_dict['d'] -= 3

Check if you use regular whitespaces for all your indents, the most likely you have tab or another space character like that instead of the whitespace.
检查所有缩进是否使用常规空格，最有可能的是制表符或其他类似的空格字符而不是空格。
Mixing space characters may lead to nice visual indents but bad for the interpreter.
混合空格字符可能会导致良好的视觉缩进，但对解释器不利。
