Python Pandas - Replace index values where the condition is False
To replace index values where the condition is False, use the index.isin() method in Pandas. At first, import the required libraries −
import pandas as pd
Creating Pandas index −
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')
Display the Pandas index −
print("Pandas Index...\n",index)Replace values where condition is False. Here, except the 'Decor', every other element gets replaced −
print("\nReplace index vales where condition is False...\n",index.where(index.isin(['Decor']), 'Miscellaneous'))Example
Following is the code −
import pandas as pd
# Creating Pandas index
index = pd.Index(['Electronics','Accessories','Decor', 'Books', 'Toys'], name ='Products')
# Display the Pandas index
print("Pandas Index...\n",index)
# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)
# Return the dtype of the data
print("\nThe dtype object...\n",index.dtype)
# replace values where condition is False
# Here, except the 'Decor', every other element gets replaced
print("\nReplace index vales where condition is False...\n",index.where(index.isin(['Decor']), 'Miscellaneous'))Output
This will produce the following output −
Pandas Index... Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], dtype='object', name='Products') Number of elements in the index... 5 The dtype object... object Replace index vales where condition is False... Index(['Miscellaneous', 'Miscellaneous', 'Decor', 'Miscellaneous','Miscellaneous'],dtype='object', name='Products')
