To check whether the interval is closed on the left-side, right-side, both or neither, use the interval.closed property.
At first, import the required libraries −
import pandas as pd
Closed interval set using the "closed" parameter with value "both". A closed interval (in mathematics denoted by square brackets) contains its endpoints, # i.e. the closed interval [0, 5] is characterized by the conditions 0 <= x <= 5
interval = pd.Interval(left=0, right=20, closed='both')
Display the interval
print("Interval...\n",interval)
Check whether the interval is closed on the left-side, right-side, both or neither
print("\nChecking for the type of Interval...\n",interval.closed)
Example
Following is the code
import pandas as pd # Closed interval set using the "closed" parameter with value "both" # A closed interval (in mathematics denoted by square brackets) contains its endpoints, # i.e. the closed interval [0, 5] is characterized by the conditions 0 <= x <= 5. interval = pd.Interval(left=0, right=20, closed='both') # display the interval print("Interval...\n",interval) # check whether the interval is closed on the left-side, right-side, both or neither print("\nChecking for the type of Interval...\n",interval.closed) # check for the existence of an element in an Interval # This shows that closed = both contains its endpoints print("\nThe left-most element exists in the Interval? = \n",0 in interval) print("\nThe right-most element exists in the Interval? = \n",20 in interval)
Output
This will produce the following code
Interval... [0, 20] Checking for the type of Interval... both
