Code # 1:
# Python program explaining # numpy.char.isnumeric () method import numpy as geek # input array contains only numeric character in_arr = geek.array ([ ’1000 ’ , ’ 2000’ ]) print ( "Input array:" , in_arr) out_arr = geek.char.isnumeric (in_arr) print ( "Output array:" , out_arr) |
Output:
Input array: [’1000’’ 2000’ ] Output array: [True True]
Code # 2:
# Python program explaining # numpy.char.isnumeric () method import numpy as geek # input array in_arr = geek.array ([ ’python3 .5’ , ’a1000’ , ’1234 ab’ ]) print ( "Input array:" , in_arr) out_arr = geek.char.isnumeric (in_arr) print ( "Output array:" , out_arr) |
Output:
Input array: [’python3.5’’ a1000’ ’1234 ab’] Output array: [False False False]
