# Python Program explaining# numpy.char.swapcase() 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.swapcase(in_arr)print ("output swapcased array :", out_arr) |
Output:
input array : ['P4Q R' '4q Rp' 'Q Rp4' 'rp4q'] output swapcasecased array : ['p4q r' '4Q rP' 'q rP4' 'RP4Q']
