Module (modules)

To meet the convenience of the maintenance program, Python provides a way to get the definition from a file, and the module refers to a file that includes Python definitions and declarations, whose file name is the module name +.py suffix, and the module name of the module can be __name__ by the global variable.

The file structure is created as follows, where modu.py is the called module, Transfer,py calls the module:

modu.py content is as follows:

Write transfer.py now

 #导入模块, introduced only the module name Modu  
 from getstartguide.modu  import modu  
  #想要访问模块下的函数, you need to use the following method  
 print (  dir (modu))   #返回字符串类型的存储列表  
 print (Modu.  __name__)  
         Operation Result:


Modu.module1 ()
Modu.module2 ()
Operation Result:


#还可为其赋一个本地名称
Function1=modu.module1
Function1 ()
Operation Result:



< Span style= "COLOR: #000080" > # You can also directly introduce the function           < Span style= "COLOR: #000080" >  
 Span style= "COLOR: #000080" >from GetStartGuide.Modu.modu import Module1 
 from GetStartGuide.Modu.modu import module2 
  #直接调用即可 
 Module1 () 
 Module2 () 
          < Span style= "COLOR: #000080" > < Span style= "COLOR: #000080" >  run Result:
