To get integer location for requested label and find the nearest index value if no exact match, use the index.get_loc(). Set the method parameter value to nearest.
At first, import the required libraries −
import pandas as pd
Creating Pandas index −
index = pd.Index([10, 20, 30, 40, 50, 60, 70])
Display the Pandas index −
print("Pandas Index...\n",index)Get the location of the nearest index value if no exact match. The value is set "nearest" using the "method" parameter of the get_loc().
print("\nGet the location of the nearest index if no exact match...\n", index.get_loc(58, method="nearest"))Example
Following is the code −
import pandas as pd
# Creating Pandas index
index = pd.Index([10, 20, 30, 40, 50, 60, 70])
# 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)
# get integer location from the given index
print("\nDisplay integer location from given index...\n",index.get_loc(20))
print("\nDisplay integer location from given index...\n",index.get_loc(50))
# Get the location of the nearest index value if no exact match
# The value is set "nearest" using the "method" parameter of the get_loc()
print("\nGet the location of the nearest index if no exact match...\n", index.get_loc(58, method="nearest"))Output
This will produce the following output −
Pandas Index... Int64Index([10, 20, 30, 40, 50, 60, 70], dtype='int64') Number of elements in the index... 7 Display integer location from given index... 1 Display integer location from given index... 4 Get the location of the nearest index if no exact match... 5
