Syntax : numpy.core.defchararray.startswith(arr, prefix, start = 0, end = None)
Parameters :
arr : [array-like of str or unicode] Array-like of str.

start, end : [int, optional] With optional start, test beginning at that position. With optional end, stop comparing at that position.
Return : [ndarray] Return the array of booleans.
Code #1 :

# Python program explaining # numpy.char.startswith() function # importing numpy as geek import numpy as geek arr = "neveropen - A computer science portal"prefix = 'Geeks' gfg = geek.char.startswith(arr, prefix, start = 0, end = None) print (gfg) |
Output :
True
