法學Python Pandas - 檢查區間是否在左側、右側、兩側或均未閉合
要檢查區間是否在左側、右側、兩側或均未閉合，請使用 interval.closed 屬性。
首先，匯入所需的庫：
import pandas as pd
使用值為“both”的“closed”引數設定閉區間。閉區間（在數學中用方括號表示）包含其端點，例如閉區間 [0, 5] 的特徵是 0 <= x <= 5
interval = pd.Interval(left=0, right=20, closed='both')
顯示區間
print("Interval...\n",interval)檢查區間是否在左側、右側、兩側或均未閉合
print("\nChecking for the type of Interval...\n",interval.closed)示例
以下是程式碼：
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)輸出
這將生成以下程式碼：
Interval... [0, 20] Checking for the type of Interval... both
