Python | sympy.sets.Lopen () method

|

With the sympy.sets.Lopen() method we can create a set of values ​​by setting the spacing values, for example, leaving open the left, which means the set has a left open parenthesis and close right parenthesis using sympy.sets.Lopen () .

Syntax: sympy.sets.Lopen ( val1, val2)
Return: Return set of values ​​with left open set.

Example # 1:
In this example, we can see that using sympy.sets.Lopen () we can find a set of values ​​by defining left open parentheses.

# import sympy

from sympy.sets import Interval

 
# Use the sympy.sets.Lopen () method

gfg = Interval.Lopen ( 0 , 10 )

print (gfg)

 

print (gfg.contains ( 8 ))

Output:

(0, 10]
True

Example # 2:

# import sympy

from sympy.sets import Interval

 
# Use the sympy method .sets.Lopen ()

gfg = Interval.Lopen ( 0 , 3 )

print (gfg)

 

print (gfg.contains ( 0 ))

(0, 3]
False
