DO YOU KNOW? What is Name-Mangling in Python! #python #shorts #programming #coding
Hey there, Python enthusiasts! Are you curious about accessing private variables in Python? Let's dive in.
In this example, we have three classes: Male, Female, and SexDetermination. Each class has a private attribute representing the chromosome. But can we access these private variables directly? Let's find out!
If we try to access a private variable directly, like Male.__chromosome, we encounter an AttributeError. Python protects these variables to maintain encapsulation. But, Anyhow we want to access those?
By using name-mangling, we can access these private variables indirectly. Now, if we use the syntax 'ClassName._ClassName__variable', we can retrieve the values of private variables. Let's see it in action!
Voila! We can access the private variable '__chromosome' in the Male class using 'Male._Male__chromosome'. The same applies to the Female class. And same goes for SexDetermination.
When we inspect the class using 'dir(SexDetermination)', we can see the power and effect of name-mangling in action. It maintains encapsulation, prevents naming conflicts, and gives us better control over accessing private variables. Thats all in this video. Thanks for watching.
class Male:
__chromosome = 'XY'
class Female:
__chromosome = 'XX'
class SexDetermination(Male, Female):
__chromosome = 'XXY'
print(Male.__chromosome)
print(Male._Male__chromosome)
print(Female._Female__chromosome)
print(SexDetermination._Male__chromosome)
print(SexDetermination._Female__chromosome)
print(SexDetermination._SexDetermination__chromosome)
print(dir(SexDetermination))
