numpy.core.defchararray.find(arr, substring, start=0, end=None): Finds the lowest index of the sub-string in the specified range.
Parameters:
arr : array-like or string to be searched.
substring : substring to search for.
start, end : [int, optional] Range to search in.Returns : An integer array with the lowest index of found sub-string.
Code #1:
# Python Program illustrating # numpy.char.find() method import numpy as np arr = ['vdsdsttetteteAAAa', 'AAAAAAAaattttds', 'AAaaxxxxtt', 'AAaaXDSDdscz'] print ("arr : ", arr) print ("\nfind of 'tt'", np.char.find(arr, 'tt')) print ("find of 'tt'", np.char.find(arr, 'tt', start = 0)) print ("find of 'tt'", np.char.find(arr, 'tt', start = 8)) |
Output:
arr : ['vdsdsttetteteAAAa', 'AAAAAAAaattttds', 'AAaaxxxxtt', 'AAaaXDSDdscz'] find of 'tt' [ 5 9 8 -1] find of 'tt' [ 5 9 8 -1] find of 'tt' [ 8 9 8 -1]
Code #2:
# Python Program illustrating # numpy.char.find() method import numpy as np arr = ['vdsdsttetteteAAAa', 'AAAAAAAaattttds', 'AAaaxxxxtt', 'AAaaXDSDdscz'] print ("\nfind of 'Aa'", np.char.find(arr, 'Aa')) print ("find of 'Aa'", np.char.find(arr, 'Aa', start = 8)) |
Output:
find of 'Aa' [15 6 1 1] find of 'Aa' [15 -1 -1 -1]
