Python Pandas - Determine if two CategoricalIndex objects contain the same elements
To determine if two CategoricalIndex objects contain the same elements, use the equals() method. At first, import the required libraries −
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"])
Check both the CategoricalIndex objects for equality −
print("\nCheck both the CategoricalIndex objects for equality...\n",catIndex1.equals(catIndex2))Example
Following is the code −
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))Output
This will produce the following output −
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
