numpy字符串操作 | isdecimal()函数

如果元素中只有十进制字符, numpy.core.defchararray.isdecimal(arr)函数对每个元素返回True ,否则返回 false。

代码#1:

# Python program explaining
# numpy.char.isdecimal() method 
  
import numpy as geek
  
# input array contains only digits
in_arr = geek.array([ '1000', '2000'] )
print ("Input array : ", in_arr) 
  
out_arr = geek.char.isdecimal(in_arr)
print ("Output array: ", out_arr)
输出:
Input array :  ['1000' '2000']
Output array:  [ True  True]


代码#2:

# Python program explaining
# numpy.char.isdecimal() method 
  
import numpy as geek
  
# input array contains digits along with space 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)
输出:
Input array :  ['1000 2' 'a1000' '1234 ab']
Output array:  [False False False]
