理解 Python 中的“IndentationError: unindent does not match any external indentation level”错误
当你遇到“IndentationError: unindent does not match Python 中出现“与任何外部缩进级别不匹配”错误,它通常表示代码缩进存在问题。缩进是 Python 语法的一个重要方面,确保其一致并遵循正确的级别非常重要。
可能的原因:混合空格和制表符
一个常见的问题导致此错误的原因是空格和制表符缩进的混合。 Python 需要一致的缩进,同时使用空格和制表符可能会混淆解释器。
解决方案:
要解决此问题,请在代码中执行搜索并替换将所有制表符替换为数量一致的空格。例如,您可以用四个空格替换所有制表符。
示例:
以下 Python 代码之前引发了缩进错误:
import sys def Factorial(n): # Return factorial result = 1 for i in range (1,n): result = result * i print "factorial is ",result return result
通过用四个空格替换所有制表符,错误得到解决:
import sys def Factorial(n): # return factorial result = 1 for i in range (1,n): result = result * i print "factorial is ",result return result print Factorial(10)
以上是为什么Python会抛出'IndentationError:unindent与任何外部缩进级别不匹配”错误?的详细内容。更多信息请关注PHP中文网其他相关文章!
