numpy字符串操作 | less_equal()函数

numpy.core.defchararray.less_equal(arr1, arr2)是另一个在 numpy 中进行字符串操作的函数。它一个一个地检查两个相同形状的字符串数组的元素，如果arr1的元素小于或等于arr2的元素，即arr1 <= arr2 ，则返回True 。否则，它返回False 。

Parameters:
arr1 : array_like of str or unicode.1st input array.
arr2 : array_like of str or unicode.2nd input array.

Returns : [ndarray] Output array of bools, or a single bool if arr1 and arr2 are scalars.

# Python program explaining
# numpy.char.less_equal() method 
  
# importing numpy 
import numpy as geek
  
# input arrays  
in_arr1 = geek.array('numpy')
print ("1st Input array : ", in_arr1)
in_arr2 = geek.array('nump')
print ("2nd Input array : ", in_arr2)  
  
# checking if in_arr1 <= in_arr2
out_arr = geek.char.less_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr) 

输出：

1st Input array :  numpy
2nd Input array :  nump
Output array:  False

代码#2：

# Python program explaining
# numpy.char.less_equal() method 
  
# importing numpy 
import numpy as geek
  
# input arrays  
in_arr1 = geek.array(['Geeks', 'for', 'Geek', 'Numpy'])
print ("1st Input array : ", in_arr1) 
in_arr2 = geek.array(['Geek', 'for', 'Geek', 'numpy'])
print ("2nd Input array : ", in_arr2) 
  
# checking if in_arr1 <= in_arr2
out_arr = geek.char.less_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr) 

输出：

1st Input array :  ['Geeks' 'for' 'Geek' 'Numpy']
2nd Input array :  ['Geek' 'for' 'Geek' 'numpy']
Output array:  [False  True  True  True]

代码#3：

# Python program explaining
# numpy.char.less_equal() method 
  
# importing numpy 
import numpy as geek
  
# input arrays  
in_arr1 = geek.array(['10', '11', '122', '15'])
print ("1st Input array : ", in_arr1) 
in_arr2 = geek.array(['10', '13', '121', '141'])
print ("2nd Input array : ", in_arr2) 
  
  
# checking if in_arr1 <= in_arr2
out_arr = geek.char.less_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr) 

输出：

1st Input array :  ['10' '11' '122' '15']
2nd Input array :  ['10' '13' '121' '141']
Output array:  [ True  True False False]
