Python library

Refactoring library

Often time we have to move library functions from files to files to reorganize. just to make sure they all functions are same between old set of files to new set of files following can be used,

compare_mods.py

import importlib

a = '''
chill_test
'''

b = '''
src.test.libtest1
books.book1.ch7
books.book1.ch8
books.book1.ch2_4
books.book1.ch5_6
experiment
'''

def funcs(mods: str) -> set:
    l = mods.strip().split()
    mods = map(importlib.import_module, l)
    dirs = map(dir, mods)
    return set([i for d in dirs for i in d])

sa = funcs(a)
sb = funcs(b)
print(sa)
print(sb)
print (sa ^ sb)

where a is the list of old python modules and b is the new ones.

Python object

it is easy to create an object and attributes.

obj = lambda: None
obj.exclude = 'hello'

Turning a dict to object

attr = {"a" : "b", "c": "d", "e": "f"}
obj = lambda: None
obj.__dict__ = attr

print(obj.a)
print(obj.c)
print(obj.e)
