Question

我尝试运行此代码，但我不断收到此错误。我不知道是什么导致错误。请有人可以帮我吗？

class Dog():
    """ A simple attempt to describe a dog"""
def __init__(self, name, age):
    """ Initialize name and age attributes."""
    self.name = name
    self.age = age
def sit(self):
    """ Simulates a dog sitting in response to a command."""
    print(f"{self.name}.title() " + "is now sitting.")
def roll_over(self):
    """ Simulates a dog rolling over in response to a command."""
    print(f"{self.name}.title() " + " rolled over.")

my_dog = Dog('willie', 6)

print("My dog's name is " +  my_dog.name.title() + ".")
print("My dog is " + str(my_dog.age) + " years old.")

错误

Answer 1

很简单-您在let mainQuestions= questions; let localQuestions = questions; mainQuestions["q-01"].title = "a";之后没有缩进任何内容。缩进它，一切都应该没事。

class Dog()

Answer 2

在python中，缩进很重要

set ::env(PYTHONPATH) {C:\Python\3.6\wherever;C:\Users\me\Python\3.6\wherever}该代码没有缩进，有在线缩进检查器，以防您遇到困难。
