Parameters:
arr: array_like of str or unicode.
Returns: [ndarray] Output array of bools.
Code # 1:
| # Python program explaining
# numpy.char.isdecimal () method import numpy as geek
# input array contains only numbers in_arr = geek.array ([ ’1000’ , ’2000’ ]) print ( "Input array:" , in_arr) out_arr = geek.char.isdecimal (in_arr) print ( "Output array:" , out_arr) |
Output :
Input array: [’1000’’ 2000’] Output array : [True True]
Code # 2:
| # Python program explaining
# numpy.char.isdecimal () method import numpy as geek
# input array contains numbers along with spaces and alphabets in_arr = geek.array ([ ’ 1000 2’ , ’a1000’ , ’ 1234 ab’ ]) print ( " Input array: " , in_arr) out_arr = geek.char.isdecimal (in_arr) print ( "Output array:" , out_arr) |
Output :
Input ar ray: [’1000 2’’ a1000’ ’1234 ab’] Output array: [False False False]
