numpy 字符串运算|大于等于()函数
原文:https://www . geesforgeks . org/numpy-string-operations-greater _ equal-function/
numpy.core.defchararray.greater_equal(arr1, arr2)是 numpy 中做字符串运算的另一个函数。如果arr1的元素大于或等于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，并返回真。否则，返回假。
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_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.greater_equal(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_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.greater_equal(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 True True False]
代码#3 :
# Python program explaining
# numpy.char.greater_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.greater_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)
Output:
1st Input array : ['10' '11' '122' '15']
2nd Input array : ['10' '13' '121' '141']
Output array: [ True False True True]
