【Python基础】IndentationError: unexpected indent

返回: Python基础 索引页

在 python-3.7.4-embed amd64\phython.exe 启动后,在 >>> 提示符下,
粘贴拷贝官方的原始的类创建程序,会报错:

程序片段:

class Dog:
 def __init__(self, name):
   self.name = name
   self.tricks = []    # creates a new empty list for each dog

 def add_trick(self, trick):
   self.tricks.append(trick)

 


错误信息:

>>>  def add_trick(self, trick):
  File "<stdin>", line 1
    def add_trick(self, trick):
    ^
IndentationError: unexpected indent
>>>    self.tricks.append(trick)
  File "<stdin>", line 1
    self.tricks.append(trick)
    ^
IndentationError: unexpected indent
>>>
   self.tricks.append(trick)

 
在两个方法的空行,加入注释行 "#####" 后,可以正常工作。

class Dog:
 def __init__(self, name):
   self.name = name
   self.tricks = []    # creates a new empty list for each dog
#############
 def add_trick(self, trick):
   self.tricks.append(trick)

 
此时,拷贝后,给出提示符 "...", 再次回车,回到 ">>>" 提示符状态。

>>> class Dog:
...  def __init__(self, name):
...    self.name = name
...    self.tricks = []    # creates a new empty list for each dog
... #############
...  def add_trick(self, trick):
...    self.tricks.append(trick)
...
>>>
