Numpy string operations | replace() function

Last Updated : 29 Aug, 2020

In the numpy.core.defchararray.replace() function, each element in arr, return a copy of the string with all occurrences of substring old replaced by new.

Syntax : numpy.core.defchararray.replace(arr, old, new, count = None)

Parameters :

arr : [array-like of str] Given array-like of string.

old : [str or unicode] Old substring you want to replace.

new : [str or unicode] New substring which would replace the old substring.

count : [int, optional] If the optional argument count is given, only the first count occurrences are replaced.

Return : [ndarray] Return the output array of str .

Code #1 :

# Python program explaining 
# numpy.char.replace() function 

# importing numpy as geek  
import numpy as geek 

gfg = geek.char.replace('GFG | a computer science portal for geeks', 'GFG', 'GeeksforGeeks')
  
print (gfg)

Output :

GeeksforGeeks | a computer science portal for geeks

Code #2 :

# Python program explaining 
# numpy.char.replace() function 

# importing numpy as geek  
import numpy as geek 

gfg = geek.char.replace('This is a python article', 'python', 'Numpy-Python', count = 1)
  
print (gfg)

Output :
