To print an object as a String in Python, you can print the desired attributes by the dot or the __repr__(), __str__() method. Follow the explanation below to understand better.
Print An Object As A String In Python
Using a dot
To print an object as a String in Python, you can use a dot and print the specified attributes of the object that you want.
Look at the example below.
# Create a class.
class Country:
def __init__(self, name=str(), capital=str(), population=0, area=0):
self.name = name
self.capital = capital
self.population = population
self.area = area
# Create a new object.
country = Country('Vietnam', 'Ha Noi', 96, 333)
# Print attributes of an object with the dot.
print('Name: {}\nCapital: {}\nPopulation: {}\nArea: {}'.format(country.name,
country.capital, country.population, country.area))Output
Name: Vietnam
Capital: Ha Noi
Population: 96
Area: 333Using the __repr__() method
Besides using the dot, you can print an object as a String by overriding the __repr__() method.
Look at the example below.
# Create a class.
class Country:
def __init__(self, name=str(), capital=str(), population=0, area=0):
self.name = name
self.capital = capital
self.population = population
self.area = area
# Override the __repr__() method.
def __repr__(self):
result_str = 'Name: {}\nCapital: {}\nPopulation: {}\nArea: {}'.format(
self.name, self.capital, self.population, self.area)
return result_str
# Create a new object.
country = Country('Vietnam', 'Ha Noi', 96, 333)
# Print attributes of an object with the repr() method.
print(repr(country))Output
Name: Vietnam
Capital: Ha Noi
Population: 96
Area: 333Using the __str__() method
In addition, you can override the __str__() method to print an object as a String in Python. After that, you can print an object by calling its name.
Look at the example below.
# Create a class.
class Country:
def __init__(self, name=str(), capital=str(), population=0, area=0):
self.name = name
self.capital = capital
self.population = population
self.area = area
# Override the __str__() method.
def __str__(self):
result_str = 'Name: {}\nCapital: {}\nPopulation: {}\nArea: {}'.format(self.name,
self.capital, self.population, self.area)
return result_str
# Create a new object.
country = Country('Vietnam', 'Ha Noi', 96, 333)
# Print attributes of an object with the __str__() method.
print(country)Output
Name: Vietnam
Capital: Ha Noi
Population: 96
Area: 333Summary
We have shown you how to print an object as a String in Python in 3 ways. Personally, you should override the __str__() method to achieve your goal because you can print an object by calling its name after overriding the __str__() method.
