The language extracted from the input variable <latex>
is Python
.
Based on the Go code example provided in the input variable <!DOCTYPE html><html>...</html>
, below is the translated code and the explanation in Python, formatted in Markdown suitable for Hugo.
The following example demonstrates how to use struct-like objects in Python by leveraging classes. Classes in Python are a way to group data together to form records.
class Person:
def __init__(self, name, age=0):
self.name = name
self.age = age
def new_person(name):
"""Construct a new Person object with the given name and default age."""
p = Person(name)
p.age = 42
return p
if __name__ == "__main__":
# This syntax creates a new object.
print(Person("Bob", 20))
# You can name the fields when initializing an object.
print(Person(name="Alice", age=30))
# Omitted fields will be zero-valued (or default-valued in Python).
print(Person(name="Fred"))
# Prefixing the instance creation can mimic pointer-like behavior by handling references.
print(new_person("Ann"))
# It’s idiomatic to encapsulate new object creation in factory functions.
print(new_person("Jon"))
# Access object fields with a dot.
s = Person(name="Sean", age=50)
print(s.name)
# You can also use dots with object references.
sp = s
print(sp.age)
# Objects are mutable.
sp.age = 51
print(sp.age)
# Anonymous struct (class in Python) type for a single value scenario.
Dog = type('Dog', (object,), {"name": "", "is_good": True})
dog = Dog()
dog.name = "Rex"
dog.is_good = True
print(f"{dog.name}, is good: {dog.is_good}")
To run the program, save the code in a .py
file and execute it using Python.
$ python script.py
<__main__.Person object at 0x7f2e00d64d90>
<__main__.Person object at 0x7f2e00d64f10>
<__main__.Person object at 0x7f2e00d64fd0>
<__main__.Person object at 0x7f2e00d650d0>
<__main__.Person object at 0x7f2e00d651d0>
Sean
50
51
Rex, is good: True
In this example:
Person
class with name
and age
fields.new_person
is a factory function that initializes a Person
object with a given name and a default age of 42.if __name__ == "__main__":
block allows the code to be run as a script and demonstrates the usage and initialization of Person
objects.type
for the Dog
object to demonstrate dynamic class creation similar to anonymous structs in some languages.
