Mathematical Operators
union()
- x.union(y) ⇒ We can use this function to return all elements present in both sets.
- x.union(y) ⇒ x|y.
Example
Python
x={10,20,30,40}
y={30,40,50,60}
print(x.union(y))
print(x|y)
Output
PowerShell
{40, 10, 50, 20, 60, 30}
{40, 10, 50, 20, 60, 30}
intersection()
- x.intersection(y) ⇒ x&y.
- Returns common elements present in both x and y.
Example
Python
x={10,20,30,40}
y={30,40,50,60}
print(x.intersection(y))
print(x&y)
Output
PowerShell
{40, 30}
{40, 30}
difference()
- x.difference(y) ⇒ x-y.
- Returns the elements present in x but not in y.
Example
Python
x={10,20,30,40}
y={30,40,50,60}
print(x.difference(y))
print(x-y)
print(y-x)
Output
PowerShell
{10, 20}
{10, 20}
{50, 60}
symmetric_difference()
- x.symmetric_difference(y) ⇒ x^y.
- Returns elements present in either x or y but not in both.
Example
Python
x={10,20,30,40}
y={30,40,50,60}
print(x.symmetric_difference(y))
print(x^y)
Output
PowerShell
{10, 50, 20, 60}
{10, 50, 20, 60}
Membership operators
- To check any element is member of set or not.
Example
Python
s=set("ajay")
print(s)
print('a' in s)
print('z' in s)
Output
PowerShell
{'a', 'j', 'a', 'y'}
True
False
