Python 程序：打印數組中偶數

編寫一個 Python 程序，使用 for 循環範圍(對於 i in range(len(evenArr))打印數組中的偶數。if 語句(if (evenArr[i] % 2 == 0))檢查每個索引位置的 numpy 數組項是否可被 2 整除。如果為真，則打印該 numpy 數組偶數。

# Print Even in Array
import numpy as np

evenArr = np.array([10, 23, 99, 40, 70, 22, 19])

print("**The List of Even Numbers in this evenArr Array***")
for i in range(len(evenArr)):
    if (evenArr[i] % 2 == 0):
        print(evenArr[i], end = "  ")

在 Python Numpy 數組輸出中打印偶數

**The List of Even Numbers in this evenArr Array***
10  40  70  22 

使用 For 循環打印數組中偶數的 Python 程序

在這個 Python 示例中，我們使用 numpy mod 和 numpy 餘數函數來檢查每個可被 2 整除的數組項的餘數是否等於零。如果為真，則從 numpy 數組中打印該偶數。

# Print Even in Array
import numpy as np
evenArr = np.array([1, 22, 99, 44, 74, 89, 190])

print("**The List of Even Numbers in this evenArr Array***")
for i in evenArr:
    if (i % 2 == 0):
        print(i, end = "  ")

print("\n\n=== Using mod function===")
print("**The List of Even Numbers in this evenArr Array***")
for i in evenArr:
    if (np.mod(i, 2) == 0):
        print(i, end = "  ")

print("\n\n=== Using remainder function===")
print("**The List of Even Numbers in this evenArr Array***")
for i in evenArr:
    if (np.remainder(i, 2) == 0):
        print(i, end = "  ")

打印 Python Numpy 數組偶數，用於循環輸出

**The List of Even Numbers in this evenArr Array***
22  44  74  190  

=== Using mod function===
**The List of Even Numbers in this evenArr Array***
22  44  74  190  

=== Using remainder function===
**The List of Even Numbers in this evenArr Array***
22  44  74  190 

Python 程序使用 While 循環返回數組中的偶數。

# Print Even in Array
import numpy as np

evenArr = np.array([44, 15, 22, 19, 148, 17, 140])
i = 0

print("**The List of Even Numbers in this evenArr Array***")
while (i < len(evenArr)):
    if (np.equal(evenArr[i] % 2, 0)):
        print(evenArr[i], end = "  ")
    i = i + 1

使用 while 循環輸出在 Python Numpy 數組中打印偶數

**The List of Even Numbers in this evenArr Array***
44  22  148  140 

在這個 Python numpy 數組的例子中，我們創建了一個檢查和打印偶數的函數(printEvenNumbers(evenArr))。

# Print Even in Array
import numpy as np

def printEvenNumbers(evenArr):
    for i in evenArr:
        if (np.remainder(i, 2) == 0):
            print(i, end = "  ")

evenArr = np.array([1, 8, 5, 22, 14, 17, 10, 18, 35, 44])
print("**The List of Even Numbers in this evenArr Array***")
printEvenNumbers(evenArr)
