Def deal_import (origin_code) : 

Import_list=[] 
Origin_code=origin_code. The lower () 
Code_lines=removeComments (origin_code) 
One_split_list=code_lines. Split (" import ") 
For twosplit one_split_list in: 
Two_spilt_list=twosplit. Split (" from ") 
Remove_list=remmove_empty (two_spilt_list) 
If len (remove_list)!=0: 
Rmas_list=rm_as (remove_list) 
Import_list=import_list + rmas_list 
Code_def=import_list [1] 
Code_import=import_list 
Code_import. Pop () 
Code_import=list (set (code_import)) 
Code_import. Sort () 
Return code_import, code_def 

As code, I want to extract the data stream,
In this code, enter the function's parameters for origin_code
Origin_code=origin_code. The lower ()
In this line, origin_code into origin_code (is actually no change)
Code_lines=removeComments (origin_code)
In this line of code that is converted into origin_code code_lines
The same method, find out the data flow:

 
Origin_code - & gt; Code_lines - & gt; One_split_list - & gt; Twosplit - & gt; Two_spilt_list - & gt; Remove_list - & gt; Rmas_list - & gt; Import_list - & gt; Code_def 

 
Origin_code - & gt; Code_lines - & gt; One_split_list - & gt; Twosplit - & gt; Two_spilt_list - & gt; Remove_list - & gt; Rmas_list - & gt; Import_list - & gt; Import_list 

Data flow is one of the two, but choose the longest data flow,

If is very complex, it if it can not judge,

Remmove_empty (two_spilt_list)

Its internal for the custom function we don't, that is, whatever it is that if the data flow

Don't know how to implement the code, I hope will be the bosses can give can implement code, thank you
