It can be installed with pip.

pip install --upgrade extepy

It works in both Python 2 and Python 3.

Features

Extension of hashlib

• extepy.filehash(obj, method="sha256", batchsize=4096) computes the hash value of a file.

Example:

from extepy import filehash
filehash("test.txt")

Extension of importlib

• extepy.reload(obj, update_global=True, update_local=True) provides advanced module and object reloading capabilities for Python, so that developer can modify code without restarting the interpreter.

This function solves key limitations of Python's built-in reloading functionality by:

• Supporting all import styles: import X, import A as X, from A import X, and from A import B as X;
• Automatically updating references without requiring reassignment;
• Offering granular control over namespace updates (global and/or local namespace).

Examples: Reload modules and objects.

from mymodule import myfunction
# ... modify myfunction() in mymodule.py ...
from extepy import reload
reload(myfunction)  # reload function

from mymodule import myfunction as myfunction1
# ... modify myfunction() in mymodule.py ...
from extepy import reload
reload(myfunction1)  # reload function alias

import mymodule
# ... modify mymodule.py ...
from extepy import reload
reload(mymodule)  # reload module
reload("mymodule")  # reload module by module name

import mymodule as mymodule1
# ... modify mymodule.py ...
from extepy import reload
reload(mymodule1)  # reload module alias

from extepy import reload
from mymodule import myfunction as myfunction1, myfunction as myfunction2
# ... modify myfunction() in mymodule.py ...
reload(myfunction1)  # update both myfunction1 and myfunction2

Examples: Update selective namespaces

from extepy import reload
myfunction = None  # global reference
def f():
    global myfunction
    from mymodule import myfunction
    # ... modify myfunction() in mymodule.py ...
    reload(myfunction, update_local=False)  # update global namespace only

from extepy import reload
def f():
    from mymodule import myfunction
    # ... modify myfunction() in mymodule.py ...
    reload(myfunction, update_global=False)  # update the local namespace only
