If you see the error “AttributeError: ‘str’ object has no attribute ‘get'” in Python, it’s likely because you’re trying to use the get() method on a string object. Read on to clarify the cause of this error and how you can fix it.
When does the AttributeError: ‘str’ object has no attribute ‘get’ occur?
The error appears when you call the get() method on an object of type string because strings do not have a ‘get’ attribute. See the example below to know.
url = "learnshareit.com"
# Try to use the get() on a string object
name = url.get("learnshareit") # Error
print(name)Error:
AttributeError: 'str' object has no attribute 'get'How to fix this problem?
We will guide you through the simple ways below to solve this problem.
Using the get() method on a dictionary
Before reading on, ensure you understand the syntax of the get() method. You can read more here.
We should use the get() method on a dictionary object or an object with the get() method to avoid the above error. Like this:
learnshareit = {
'url': 'learnshareit.com',
'name': 'LearnShareIT'
}
# Use get() on a dict
name = learnshareit.get('name')
print(name) # LearnShareITOutput:
LearnShareITUsing the type() method
The type() method is a built-in method that returns an object’s class or data type.
Syntax:
type(obj)
Description:
It returns the class or data type of the obj.
This way, we can check whether an object is a dictionary using the type() method. If it is, we can use get() on that object; otherwise, we will print a message line.
learnshareit = {
'url': 'learnshareit.com',
'name': 'LearnShareIT'
}
url = learnshareit['url']
# Use type() to check the object before using get()
if type(url) == dict:
name = url.get('name')
print(name)
else:
print('Cannot use get() on this object!')Output:
Cannot use get() on this object!Using the hasattr() method
The hasattr() method is a built-in function in Python that checks if an object has the given attribute. This is useful when you want to know if an object has a certain property without actually having to access it. You can read more about its syntax here.
First, we check if the object has the get attribute using hasattr(). If it does, we can use get() on that object. If not, it means that the object has no get attribute. Like this:
learnshareit = {
'url': 'learnshareit.com',
'name': 'LearnShareIT'
}
# Use hasattr() to check if an object can use get()
if hasattr(learnshareit, 'get'):
name = learnshareit.get('name')
print(name) # LearnShareIT
else:
print('Cannot use get() on this object!')Output:
LearnShareITSummary
The best way to fix the AttributeError: ‘str’ object has no attribute ‘get’ is to check if a particular attribute exists in our object using hasattr(). If this article was helpful to you, we’re glad it did.
