What are the different data types of set items in Python?
Overview
A set in Python is a collection of multiple unordered and unchangeable items in a single variable.
Sets are written using the curly braces {}.
For example:
myset = {"USA", "CANADA", "BRAZIL"}
From the code above, the variable myset represents the set while "USA", "CANADA", and "BRAZIL" represent the items of the set.
Data types of set items
A set can be of any data type: a string, int, or the boolean data types.
Example 1
In the code below, we will create sets of different data types and print them.
Code
# creating a string data type items of setstringset = {"USA", "CANADA", "BRAZIL"}# creating an integer data type items of setintset = {1, 2, 3, 4, 5}# crating a boolean data type items of setboolset = {True, False, False}# printing our setsprint(stringset)print(intset)print(boolset)
Code explanation
- Line 2: We create a set with items of string data type.
- Line 5: We create a set with items of integer data type.
- Line 7: We create a set with items of Boolean data type.
- Lines 11-13: We print these sets.
As we can see, we are able to create sets having items of different data types by using the curly braces {}.
Interestingly, the same set can also contain items of different data types.
Example 2
In the code below, we will create a set that contains items of string, integer, and Boolean data types.
# creating a set with different data typesmyset = {"abc", 34, True, 40, "male", "Hello", 20, "False"}# printing the setprint(myset)
Code explanation
- Line 2: We create a set with items of different data types in it.
- Line 5: We print the set.
