numpy string operations | lower() function
numpy.core.defchararray.lower(arr) function is used to return an array with the elements converted to lowercase.
Parameters:
arr : [ array_like ] Input array which may be str or unicode.Returns : [ndarray] Output lowercased array of str or unicode, depending on input type.
Code #1:
# 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(['GEEKS', 'FOR', 'GEEKS']) print ("input array : ", in_arr) out_arr = geek.char.lower(in_arr)print ("output lowercased array :", out_arr ) |
Output:
input array : ['GEEKS' 'FOR' 'GEEKS'] output lowercased array : ['geeks' 'for' 'geeks']
