Python 程序查找数组中奇偶数的和

使用 for 循环 range 编写 Python 程序来查找数组中奇偶数的和。if 条件 (if (evenOddSumArr[i] % 2 == 0)) 检查数组项是否可以被二整除。如果为 True，我们将该数组项添加到 evnArrSum。否则，将该数组值添加到 oddArrSum。

# Sum of Even and Odd in Array

import numpy as np

evenOddSumArr = np.array([10, 25, 199, 450, 70, 111, 190, 7])
evenArrSum = 0
oddArrSum = 0

for i in range(len(evenOddSumArr)):
    if (evenOddSumArr[i] % 2 == 0):
        evenArrSum = evenArrSum + evenOddSumArr[i]
    else:
        oddArrSum = oddArrSum + evenOddSumArr[i]

print("The Sum of Even Numbers in evenOddSumArr Array = ", evenArrSum)
print("The Sum of Odd Numbers in evenOddSumArr Array  = ", oddArrSum)

Python 程序查找数组中奇偶数的和

在此 Python 示例中，我们使用 for 循环迭代数组项。numpy mod 和 remainder 函数检查每个 数组 项除以二的余数是否等于零。

# Sum of Even and Odd in Array

import numpy as np

evenOddSumArr = np.array([10, 199, 14, 450, 170, 191, 200, 700])
evenArrSum = evenArrSum1 = evenArrSum2 = 0
oddArrSum = oddArrSum1 = oddArrSum2 = 0

for i in evenOddSumArr:
    if (i % 2 == 0):
        evenArrSum = evenArrSum + i
    else:
        oddArrSum = oddArrSum + i

print("The Sum of Even Numbers in evenOddSumArr Array = ", evenArrSum)
print("The Sum of Odd Numbers in evenOddSumArr Array  = ", oddArrSum)

print("\n=== Using mod function===")
for i in evenOddSumArr:
    if (np.mod(i, 2) == 0):
        evenArrSum1 = evenArrSum1 + i
    else:
        oddArrSum1 = oddArrSum1 + i

print("The Sum of Even Numbers in evenOddSumArr Array = ", evenArrSum1)
print("The Sum of Odd Numbers in evenOddSumArr Array  = ", oddArrSum1)

print("\n=== Using remainder function===")
for i in evenOddSumArr:
    if (np.remainder(i, 2) == 0):
        evenArrSum2 = evenArrSum2 + i
    else:
        oddArrSum2 = oddArrSum2 + i

print("The Sum of Even Numbers in evenOddSumArr Array = ", evenArrSum2)
print("The Sum of Odd Numbers in evenOddSumArr Array  = ", oddArrSum2)

Numpy 数组中奇偶数之和的输出

The Sum of Even Numbers in evenOddSumArr Array =  1544
The Sum of Odd Numbers in evenOddSumArr Array  =  390

=== Using mod function===
The Sum of Even Numbers in evenOddSumArr Array =  1544
The Sum of Odd Numbers in evenOddSumArr Array  =  390

=== Using remainder function===
The Sum of Even Numbers in evenOddSumArr Array =  1544
The Sum of Odd Numbers in evenOddSumArr Array  =  390

使用 While 循环计算数组中奇偶数之和的 Python 程序。

# Sum of Even and Odd in Array

import numpy as np

evenOddSumArr = np.array([10, 25, 40, 75, 100, 125, 1100, 175])
i = 0
evenArrSum = evenArrSum1 = evenArrSum2 = 0
oddArrSum = oddArrSum1 = oddArrSum2 = 0

while (i < len(evenOddSumArr)):
    if (np.equal(evenOddSumArr[i] % 2, 0)):
        evenArrSum = evenArrSum + evenOddSumArr[i]
    else:
        oddArrSum = oddArrSum + evenOddSumArr[i]
    i = i + 1

print("The Sum of Even Numbers in evenOddSumArr Array = ", evenArrSum)
print("The Sum of Odd Numbers in evenOddSumArr Array  = ", oddArrSum)

使用 while 循环的 Numpy 数组奇偶数之和输出。

The Sum of Even Numbers in evenOddSumArr Array =  1250
The Sum of Odd Numbers in evenOddSumArr Array  =  400

在此 numpy 数组示例中，我们创建了一个 (SumEvenOddNumbers(evenOddSumArr)) 函数，该函数返回奇数和偶数的和。

# Sum of Even and Odd in Array

import numpy as np

def SumEvenOddNumbers(evenOddSumArr):
    evenArrSum = 0
    oddArrSum = 0
    for i in evenOddSumArr:
        if (np.remainder(i, 2) == 0):
            evenArrSum = evenArrSum + i
        else:
            oddArrSum = oddArrSum + i

    return evenArrSum, oddArrSum


evenOddSumArr = np.array([10, 20, 25, 55, 100, 85, 200])
evensum, oddsum = SumEvenOddNumbers(evenOddSumArr)

print("The Sum of Even Numbers in evenOddSumArr Array = ", evensum)
print("The Sum of Odd Numbers in evenOddSumArr Array  = ", oddsum)

使用函数的 Numpy 数组奇偶数之和输出

The Sum of Even Numbers in evenOddSumArr Array =  330
The Sum of Odd Numbers in evenOddSumArr Array  =  165
