Python Pandas - 建立半開時間區間並檢查端點是否存在

要建立一個半開時間區間，請使用 pandas.Interval() 並將 closed 引數設定為 left。要檢查端點是否存在，請使用此 in 屬性。

首先，匯入所需的庫 -

import pandas as pd

半開區間使用帶有值 “left” 的 “closed” 引數設定。當 closed='left'，半開區間 [0, 5) 由 0 <= x < 5 描述。

interval = pd.Interval(left=0, right=20, closed='left')

顯示區間

print("Interval...\n",interval)

檢查區間中元素是否存在。這表明 closed = left 僅包含最左側的端點

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)

示例

以下為程式碼

import pandas as pd

# Half-Open interval set using the "closed" parameter with value "left"
# Half-open i.e. [0, 5) is described by 0 <= x < 5 when closed='left'
interval = pd.Interval(left=0, right=20, closed='left')

# display the interval
print("Interval...\n",interval)

# display the interval length
print("\nInterval length...\n",interval.length)

# check for the existence of an element in an Interval
# This shows that closed = left contain only the left-most endpoint
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)

Interval length...
20
