比較兩個NumPy陣列,如果第一個陣列大於等於第二個陣列,則返回True
要比較兩個陣列,如果第一個陣列大於等於第二個陣列,則返回True,可以使用Python NumPy中的**numpy.char.greater_equal()**方法。arr1和arr2是兩個形狀相同的輸入字串陣列。
與numpy.greater_equal不同,此比較是在首先去除字串末尾的空格字元後執行的。此行為是為了與numarray向後相容。
numpy.char模組為numpy.str_或numpy.bytes_型別的陣列提供了一組向量化字串操作。
步驟
首先,匯入所需的庫:
import numpy as np
建立兩個一維字串陣列:
arr1 = np.array(['Bella', 'Tom', 'John', 'Kate', 'Amy', 'Brad', 'aaa']) arr2 = np.array(['Cio', 'Tom', 'Cena', 'Kate', 'Adams', 'brad', 'aa'])
顯示陣列:
print("Array 1...
", arr1)
print("
Array 2...
", arr2)獲取陣列的型別:
print("
Our Array 1 type...
", arr1.dtype)
print("
Our Array 2 type...
", arr2.dtype)獲取陣列的維度:
print("
Our Array 1 Dimensions...
",arr1.ndim)
print("
Our Array 2 Dimensions...
",arr2.ndim)獲取陣列的形狀:
print("
Our Array 1 Shape...
",arr1.shape)
print("
Our Array 2 Shape...
",arr2.shape)要比較兩個陣列,如果第一個陣列大於等於第二個陣列,則返回True,可以使用numpy.char.greater_equal()方法。arr1和arr2是兩個形狀相同的輸入字串陣列:
print("
Result...
",np.char.greater_equal(arr1,arr2))示例
import numpy as np
# Create two One-Dimensional arrays of string
arr1 = np.array(['Bella', 'Tom', 'John', 'Kate', 'Amy', 'Brad', 'aaa'])
arr2 = np.array(['Cio', 'Tom', 'Cena', 'Kate', 'Adams', 'brad', 'aa'])
# Display the arrays
print("Array 1...
", arr1)
print("
Array 2...
", arr2)
# Get the type of the arrays
print("
Our Array 1 type...
", arr1.dtype)
print("
Our Array 2 type...
", arr2.dtype)
# Get the dimensions of the Arrays
print("
Our Array 1 Dimensions...
",arr1.ndim)
print("
Our Array 2 Dimensions...
",arr2.ndim)
# Get the shape of the Arrays
print("
Our Array 1 Shape...
",arr1.shape)
print("
Our Array 2 Shape...
",arr2.shape)
# To compare and return True if an array is greater than equal to another, use the numpy.char.greater_equal() method in Python Numpy
# The arr1 and arr2 are the two input string arrays of the same shape.
print("
Result...
",np.char.greater_equal(arr1,arr2))輸出
Array 1... ['Bella' 'Tom' 'John' 'Kate' 'Amy' 'Brad' 'aaa'] Array 2... ['Cio' 'Tom' 'Cena' 'Kate' 'Adams' 'brad' 'aa'] Our Array 1 type... <U5 Our Array 2 type... <U5 Our Array 1 Dimensions... 1 Our Array 2 Dimensions... 1 Our Array 1 Shape... (7,) Our Array 2 Shape... (7,) Result... [False True True True True False True]
