numpy 字符串操作|更大()函数

原文:https://www . geesforgeks . org/numpy-string-operations-greater-function/

numpy.core.defchararray.greater(arr1, arr2)是 numpy 中做字符串运算的另一个函数。如果arr1的元素大于arr2的元素,即arr1 > arr2 ,则逐个检查两个相同形状的字符串数组的元素,并返回。否则,返回

参数: arr1 : 字符串或 unicode.1st 输入数组的 array_like。 arr2 : 字符串或 unicode 的 array _ like . 2nd 输入数组。

返回:【ndarray】bool 的输出数组,如果 arr1 和 arr2 是标量,则返回单个 bool。

代码#1 :

# Python program explaining
# numpy.char.greater() 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.greater(in_arr1, in_arr2)
print ("Output array: ", out_arr) 

Output:

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

代码#2 :

# Python program explaining
# numpy.char.greater() 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.greater(in_arr1, in_arr2)
print ("Output array: ", out_arr) 

Output:

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

代码#3 :

# Python program explaining
# numpy.char.greater() 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', '14'])
print ("2nd Input array : ", in_arr2) 

# checking if in_arr1 > in_arr2
out_arr = geek.char.greater(in_arr1, in_arr2)
print ("Output array: ", out_arr) 

Output:

1st Input array :  ['10' '11' '122' '15']
2nd Input array :  ['10' '13' '121' '14']
Output array:  [False False  True  True]
