Python - Show which entries in a Pandas Index are NA
To show which entries in a Pandas Index are NA, use the index.isna() in Pandas. At first, import the required libraries -
import pandas as pd import numpy as np
Creating Pandas index with some NaN values −
index = pd.Index([5, 65, np.nan, 17, 75, np.nan])
Display the Pandas index −
print("Pandas Index...\n",index)
Show which entries in a Pandas index are NA. Return True for NA entries −
print("\nCheck which entries are NA...\n", index.isna())
Example
Following is the code −
import pandas as pd import numpy as np # Creating Pandas index with some NaN values index = pd.Index([5, 65, np.nan, 17, 75, np.nan]) # 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) # Show which entries in a Pandas index are NA # Return True for NA entries print("\nCheck which entries are NA...\n", index.isna())
Output
This will produce the following output −
Pandas Index... Float64Index([5.0, 65.0, nan, 17.0, 75.0, nan], dtype='float64') Number of elements in the index... 6 The dtype object... float64 Check which entries are NA... [False False True False False True]
