Python 3 – dictionary type() Method
In Python, a dictionary is a collection of key-value pairs. We can use the type()
method to determine the type of a dictionary object.
Syntax:
Here is the basic syntax of the type()
method in Python:
type(obj)
The obj
parameter is the object whose type is to be returned.
Example:
Here is an example of how to use the type()
method to find the type of a dictionary object:
# define a dictionary object
grades = {'Alice': 98, 'Bob': 88, 'Charlie': 77}
# print the type of the dictionary object
print(type(grades))
Output:
<class 'dict'>
Here, we have defined a dictionary object called grades
. We then use the type()
method to find the type of this object, which is dict
.
Explanation:
The type()
method returns the type of the object passed to it as a parameter. In the example above, we passed the grades
dictionary object as a parameter to the type()
method. The method then returns the type of the object, which is dict
.
Benefits:
The type()
method is useful in situations where we may not be sure of the type of an object. It can be used to check the type of different objects, including dictionaries.
Conclusion
The type()
method is a useful built-in function in Python that allows us to determine the type of an object. It is particularly useful when working with complex data types like dictionaries. With this method, we can easily determine that a variable is a dictionary and avoid errors that might occur if we try to use it as a different data type.
