How to get the data type of a set in Python
Onyejiaku Theophilus ChidaluOverview
A set in Python is a collection of unordered and unchangeable items in a single variable. Sets are created or written inside curly braces {}.
For example:
myset = {"USA", "CANADA", "BRAZIL"}
The variable myset represents the set in the code above, while USA, CANADA, and BRAZIL are the elements of the set.
Data types of set
A set can contain the following data types:
- String data type
- Integer data type
- Boolean data type
- A combination of the string, integer, or Boolean data types
It is worth noting that Python will always return
<class 'set'>to let you know that what you created is a set.
Example
In the code below, we will create sets of items of the different data types mentioned above.
# creating a string data type items of set
stringset = {"USA", "CANADA", "BRAZIL"}
# creating an integer data type items of set
intset = {1, 2, 3, 4, 5}
# crating a boolean data type items of set
boolset = {True, False, False}
# creating a set containing different data types
myset = {"abc", 34, True, 40, "male", "Hello", 20, "False"}
# printing our sets
print(stringset)
print(intset)
print(boolset)
print(myset)Explanation
In the code above, we create three sets, one each for a string, integer, and Boolean data type, and one with items of multiple data types.
Getting the data type of a set
To get the data type of a set, we make use of the type() function.
Syntax
type(set)
Parameter value
The type() function takes a single parameter value that represents the set.
Return value
The type() function will return the set data type, <class 'set'>.
Code
# creating a set
thisset = {"apple", "banana", "cherry"}
print(type(thisset))
Note: Python will always define a set as objects with data type
set. Hence, the output of the code above is<class 'set'>.
