# Python Program explaining 
# numpy.char.lower() function  
  
import numpy as geek  
  
  
in_arr = geek.array(['P4Q R', '4Q RP', 'Q RP4', 'RP4Q']) 
print ("input array : ", in_arr) 
  
out_arr = geek.char.lower(in_arr) 
print ("output lowercased array :", out_arr) 

Output:

input array :  ['P4Q R' '4Q RP' 'Q RP4' 'RP4Q']
output lowercased array : ['p4q r' '4q rp' 'q rp4' 'rp4q']

Code #2:

# Python Program explaining 
# numpy.char.lower() function  
  
import numpy as geek  
  
in_arr = geek.array(['Beginner', 'FOR', 'Beginner']) 
  
print ("input array : ", in_arr) 
  
out_arr = geek.char.lower(in_arr)
