IndentationError是否是Python中的语法错误？

I have a simple question,

我有一个简单的问题，

Is IndentationError a SyntaxError in Python or not?

IndentationError是否是Python中的SyntaxError？

I think it is not but since I am a beginner I would like to be sure. Are syntax errors only those which give me SyntaxError as a response in an interpreter? For example, if I type

我认为不是，但因为我是初学者，我想确定。语法错误只是那些在解释器中将SyntaxError作为响应的错误吗？例如，如果我输入

3f = 22

I get

我明白了

SyntaxError: invalid syntax

So if there's something else (IndentationError etc), may it be a sub-type of SyntaxError or not?

所以，如果还有其他东西（IndentationError等），它可能是SyntaxError的子类型吗？

2 个解决方案

#1

>>> issubclass(IndentationError, SyntaxError)
True

It means yes

这意味着是的

Your example is a SyntaxError, because you can't have an identifier that starts with a number:

您的示例是SyntaxError，因为您不能拥有以数字开头的标识符：

>>> 3f = 22
  File "<stdin>", line 1
    3f = 22
     ^
SyntaxError: invalid syntax


>>>     f3 = 22
  File "<stdin>", line 1
    f3 = 22
    ^
IndentationError: unexpected indent


>>> def test():
... f3 = 22
  File "<stdin>", line 2
    f3 = 22
     ^
IndentationError: expected an indented block

An IndentationError is a kind of SyntaxError, see the method resolution order in: help(IndentationError) and: http://docs.python.org/2/library/exceptions.html#exceptions.IndentationError

IndentationError是一种SyntaxError，请参阅以下方法中的方法解析顺序：help（IndentationError）和：http：//docs.python.org/2/library/exceptions.html#exceptions.IndentationError

Valid identifiers:

有效标识符：

test
test3
test_3
__3Test_3______

Invalid identifiers:

标识符无效：

3f
333
33__
# Using any symbol other than: _

>>> issubclass(IndentationError, SyntaxError)
True
