python import使用方法？

为什么import xxx，会直接运行该模块呢？

1. x = "There are {0} types of people.\n".format(10)
   
2. binary = "binary"
   
3. do_not = "don't"
   
4. y = "Those who know {0} and those who {1}".format(binary,do_not)
   
5. print(x+y)
   
6. print("I said: {0}".format(x))
   
7. print("I also said: {0}".format(y))
   
8. 
   
9. hilarious = False
   
10. joke_evaluation = "Isn't that joke so funny ? {0}"
    
11. print (joke_evaluation.format(hilarious))

直接在c**ole里Import ex6,会打印出图片的内容，为什么会直接运行呢


但直接print （x）又会报错，此时x不是已经被导入了吗
>>>print (x)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
NameError: name 'x' is not defined

如果可以的话可以百度入口函数
调用模块里的值的话，应该是ex6.x
