How Python divides modules
This article introduces the relevant knowledge of "how to divide the module of Python". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
First step, split rule
Copy the code from the rule section to a new file: rule.py, and comment or delete the original code. For comparison here, DE8UG commented on file 08, see the last code.
# rule.py
# author: DE8UG
# PROJECT: rengleme
Rule = {
"Wet garbage": ["vegetable leaves", "orange peel", "spring onions", "biscuits"]
"dry garbage": ["old bathtub", "basin", "sponge", "toilet paper"]
}
The second step is to split the core code for dealing with garbage
Create a new file: handle_laji.py, and copy the function for dealing with garbage sorting here.
# handle_laji.py
# author: DE8UG
# PROJECT: rengleme
Def reng_laji (rule_k, laji, ljt):
If rule_k = = ljt ['name']:
Ljt ['data'] .append (laji)
Def fenlei (laji, rule, ljt):
For k, v in rule.items ():
Print (k, v)
If laji in v:
Print ('garbage found:', laji, k)
Reng_laji (k, laji, ljt)
The third step is to process files, load and save garbage
Create a new file: handle_file.py, and copy the function for processing the file here.
# handle_file.py
# author: DE8UG
# PROJECT: rengleme
Import json
# print ('load file:', ljt_gan)
Def load_data (filename):
With open (filename) as f:
Data = json.load (f)
Return data
# encapsulate the code for writing files with functions
Def save_to_file (filename, data):
With open (filename,'w') as f:
Json.dump (data, f)
The fourth step, improve the code, test
Delete the removed code from the 08 file (I've only commented here for comparison), and then import the previous new py files first.
Note: these files need to be in one directory to avoid the situation that files can not be found in different paths.
After import imports the corresponding module, the subsequent function needs to use the module. Called by the name of the function. Please add the required function name yourself. Then conduct a code test. If there is no problem, our new transformation will be completed today.

# reng_laji (k, laji, ljt_shi)
# encapsulate the code for writing files with functions
# def save_to_file (filename, data):
# with open (filename,'w') as f:
# json.dump (data, f)
Def main ():
# define trash cans
Ljt_shi = {
Name': "wet rubbish"
'data': []
}
Ljt_gan = {
Name': "dry trash"
'data': []
}
# load existing garbage
Ljt_gan = handle_file.load_data ('gan.json')
Ljt_shi = handle_file.load_data ('shi.json')
Print ('load file:', ljt_gan, ljt_shi)
# throw out the trash
Laji = input ("enter garbage to throw:")
Print ("junk:", laji)
# Classification
Handle_laji.fenlei (laji, rule, ljt_gan)
Handle_laji.fenlei (laji, rule, ljt_shi)
Print ('- * 20)
Print (ljt_shi)
Print (ljt_gan)
# call the function and save to the specific trash file
Handle_file.save_to_file ('gan.json', ljt_gan)
Handle_file.save_to_file ('shi.json', ljt_shi)
If _ name__ = = "_ _ main__":
Main ()
