Python 程序打印数组中的偶数

使用 for 循环 range（for i in range(len(evenArr))）编写一个 Python 程序来打印数组中的偶数。if 语句（if (evenArr[i] % 2 == 0)）检查每个索引位置的 numpy 数组项是否可以被 2 整除。如果是 True，则打印 numpy 数组中的偶数。

# 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 = "  ")

打印 Python Numpy 数组中的偶数输出

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

使用 For 循环打印 Python 数组中的偶数

在此 Python 示例中，我们使用了 numpy mod 和 numpy remainder 函数来检查每个数组项除以 2 的余数是否等于零。如果是 True，则打印 numpy 数组中的偶数。

# 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 = "  ")

使用 for 循环打印 Python Numpy 数组偶数输出

**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 循环返回数组中的偶数。

# 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 循环打印 Python Numpy 数组中的偶数输出

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

在此 Python numpy 数组示例中，我们创建了一个函数（printEvenNumbers(evenArr)），用于检查和打印偶数。

# 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)
