编写一个 Python 程序来计算数组中的偶数和奇数,用于循环范围。if 条件(if (evenOddArr[i] % 2 == 0))检查数组项是否可被二整除。如果为真,我们将偶数数组计数加 1;否则,将奇数数组计数值加 1。
# Count Even and Odd in Array
import numpy as np
evenOddArr = np.array([10, 99, 22, 50, 77, 22, 112, 19])
print("The List of Numbers in evenOddArr Array = ", evenOddArr)
evenArrCount = 0
oddArrCount = 0
for i in range(len(evenOddArr)):
if (evenOddArr[i] % 2 == 0):
evenArrCount = evenArrCount + 1
else:
oddArrCount = oddArrCount + 1
print("The Count of Even Numbers in evenOddArr Array = ", evenArrCount)
print("The Count of Odd Numbers in evenOddArr Array = ", oddArrCount)
计算数组中偶数和奇数的 Python 程序
在这个 Python 例子中,我们使用 numpy mod 和余数函数来检查每个项目的余数是否等于零。
# Count Even and Odd in Array
import numpy as np
evenArr = np.array([4, 29, 88, 5, 0, 11, 17, 18, 7, 44, 9, 89])
evenArrCount = evenArrCount1 = evenArrCount2 = 0
oddArrCount = oddArrCount1 = oddArrCount2 = 0
for i in evenArr:
if (i % 2 == 0):
evenArrCount = evenArrCount + 1
else:
oddArrCount = oddArrCount + 1
print("The Count of Even Numbers in evenOddArr Array = ", evenArrCount)
print("The Count of Odd Numbers in evenOddArr Array = ", oddArrCount)
print("\n=== Using mod function===")
for i in evenArr:
if (np.mod(i, 2) == 0):
evenArrCount1 = evenArrCount1 + 1
else:
oddArrCount1 = oddArrCount1 + 1
print("The Count of Even Numbers in evenOddArr Array = ", evenArrCount1)
print("The Count of Odd Numbers in evenOddArr Array = ", oddArrCount1)
print("\n=== Using remainder function===")
for i in evenArr:
if (np.remainder(i, 2) == 0):
evenArrCount2 = evenArrCount2 + 1
else:
oddArrCount2 = oddArrCount2 + 1
print("The Count of Even Numbers in evenOddArr Array = ", evenArrCount2)
print("The Count of Odd Numbers in evenOddArr Array = ", oddArrCount2)
Python 计算 Numpy 数组输出中的偶数和奇数
The Count of Even Numbers in evenOddArr Array = 5
The Count of Odd Numbers in evenOddArr Array = 7
=== Using mod function===
The Count of Even Numbers in evenOddArr Array = 5
The Count of Odd Numbers in evenOddArr Array = 7
=== Using remainder function===
The Count of Even Numbers in evenOddArr Array = 5
The Count of Odd Numbers in evenOddArr Array = 7
Python 程序使用 While 循环计算 Numpy 数组中的偶数和奇数。
# Count Even and Odd in Array
import numpy as np
evenOddArr = np.array([4, 15, 19, 22, 9, 18, 140])
i = 0
evenArrCount = 0
oddArrCount = 0
while (i < len(evenOddArr)):
if (np.equal(evenOddArr[i] % 2, 0)):
evenArrCount = evenArrCount + 1
else:
oddArrCount = oddArrCount + 1
i = i + 1
print("The Count of Even Numbers in evenOddArr Array = ", evenArrCount)
print("The Count of Odd Numbers in evenOddArr Array = ", oddArrCount)
使用 While 循环输出 计算 Python Numpy 数组中的偶数和奇数
The Count of Even Numbers in evenOddArr Array = 4
The Count of Odd Numbers in evenOddArr Array = 3
在这个 Python numpy 数组的例子中,我们创建了一个(counterevenoddles(evenOddArr))函数,返回偶数和奇数的计数。
# Count Even and Odd in Array
import numpy as np
def CountEvenOddNumbers(evenOddArr):
evenArrCount = 0
oddArrCount = 0
for i in evenOddArr:
if (np.remainder(i, 2) == 0):
evenArrCount = evenArrCount + 1
else:
oddArrCount = oddArrCount + 1
return evenArrCount, oddArrCount
evenOddArr = np.array([11, 88, 15, 122, 140, 17, 10, 48, 35, 64])
even, odd = CountEvenOddNumbers(evenOddArr)
print("The Count of Even Numbers in evenOddArr Array = ", even)
print("The Count of Odd Numbers in evenOddArr Array = ", odd)
使用函数输出计算 Numpy 数组中的偶数和奇数
The Count of Even Numbers in evenOddArr Array = 6
The Count of Odd Numbers in evenOddArr Array = 4
