Python Pandas - Return a sorted copy of the index
To return a sorted copy of the index, use the index.sort_values() method in Pandas. At first, import the required libraries −
import pandas as pd
Creating Pandas index −
index = pd.Index([50, 10, 70, 95, 110, 90, 30])
Display the Pandas index −
print("Pandas Index...\n",index)Sort index values. By default, sorts in Ascending order −
print("\nSort the index values...\n",index.sort_values())
Example
Following is the code −
import pandas as pd
# Creating Pandas index
index = pd.Index([50, 10, 70, 95, 110, 90, 30])
# 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)
# Sort index values
# By default, sorts in Ascending order
print("\nSort the index values...\n",index.sort_values())Output
This will produce the following output −
Pandas Index... Int64Index([50, 10, 70, 95, 110, 90, 30], dtype='int64') Number of elements in the index... 7 The dtype object... int64 Sort the index values... Int64Index([10, 30, 50, 70, 90, 95, 110], dtype='int64')
