Project description
refdatatypes
Pyton basic datatypes as a references. Solve problems with static class immutable datatypes.
Installation
pip3 install refdatatypes
Problem
class A:
static = 1
class B(A):
pass
print(f"int {A.static}") # get 1 correctly
print(f"int {B.static}") # get 1 correctly
A.static = 5
print(f"int {A.static}") # get 5 correctly
print(f"int {B.static}") # get 5 correctly
B.static = 6
print(f"int {A.static}") # expected 6, but get 5 incorrectly
print(f"int {B.static}") # get 6 correctly
A.static = 7
print(f"int {A.static}") # get 7 correctly
print(f"int {B.static}") # get unchanged 6
Solution
from refdatatypes.refint import RefInt
class AAA:
static = RefInt(1)
class BBB(AAA):
pass
print(f"refint {AAA.static.value}") # get 1 correctly
print(f"refint {BBB.static.value}") # get 1 correctly
AAA.static.value = 5
print(f"refint {AAA.static.value}") # get 5 correctly
print(f"refint {BBB.static.value}") # get 5 correctly
BBB.static.value = 6
print(f"refint {AAA.static.value}") # get 6 correctly
print(f"refint {BBB.static.value}") # get 6 correctly
AAA.static.value = 7
print(f"refint {AAA.static.value}") # get 7 correctly
print(f"refint {BBB.static.value}") # get 7 correctly
