法學Python Pandas - 判斷兩個 CategoricalIndex 物件是否包含相同的元素
要確定兩個 CategoricalIndex 物件是否包含相同的元素，請使用 equals() 方法。首先，匯入所需的庫 −
import pandas as pd
使用 "categories" 引數為分類設定類別。使用 "ordered" 引數將類別視為有序的。建立兩個 CategoricalIndex 物件 −
catIndex1 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"]) catIndex2 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"])
檢查兩個 CategoricalIndex 物件是否相等 −
print("\nCheck both the CategoricalIndex objects for equality...\n",catIndex1.equals(catIndex2))示例
以下是程式碼 −
import pandas as pd
# Set the categories for the categorical using the "categories" parameter
# Treat the categorical as ordered using the "ordered" parameter
# Create two CategoricalIndex objects
catIndex1 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"])
catIndex2 = pd.CategoricalIndex(["p", "q", "r", "s","p", "q", "r", "s"], ordered=True, categories=["p", "q", "r", "s"])
# Display the CategoricalIndex objects
print("CategoricalIndex1...\n",catIndex1)
print("\nCategoricalIndex2...\n",catIndex2)
# Check both the CategoricalIndex objects for equality
print("\nCheck both the CategoricalIndex objects for equality...\n",catIndex1.equals(catIndex2))輸出
這將產生以下輸出 −
CategoricalIndex1... CategoricalIndex(['p', 'q', 'r', 's', 'p', 'q', 'r', 's'], categories=['p', 'q', 'r', 's'], ordered=True, dtype='category') CategoricalIndex2... CategoricalIndex(['p', 'q', 'r', 's', 'p', 'q', 'r', 's'], categories=['p', 'q', 'r', 's'], ordered=True, dtype='category') Check both the CategoricalIndex objects for equality... True
