With the help of sympy.sets.Lopen() method, we can make a set of values by setting interval values like left open that means a set has left open bracket and right close one by using sympy.sets.Lopen() method.
Syntax : sympy.sets.Lopen(val1, val2) Return : Return set of values with left open set.
Example #1 : In this example we can see that by using sympy.sets.Lopen() method, we are able to find the set of values by defining left open brackets. Python3 1=1
# import sympy
from sympy.sets import Interval

# Use sympy.sets.Lopen() method
gfg = Interval.Lopen(0, 10)
print(gfg)
  
print(gfg.contains(8))
Output :
(0, 10] True
Example #2 : Python3 1=1
# import sympy
from sympy.sets import Interval

# Use sympy.sets.Lopen() method
gfg = Interval.Lopen(0, 3)
print(gfg)
  
print(gfg.contains(0))
(0, 3] False
