写一个 Python 程序来计算一个数组或 Numpy 元素数组的平均值。Python Numpy 模块有求和和求平均值的方法来求数组项的求和和求平均值。
import numpy as np
arr = np.array([10, 20, 40, 60, 80, 100])
total = arr.sum()
avg = np.average(arr)
print('\nThe Sum Of Array Elements = ', total)
print('\nThe Average Of Array Elements = ', avg)这个 python 程序使用 for 循环来迭代 Numpy Array 项，并计算所有元素的总和和平均值。
import numpy as np
arr = np.array([14, 25, 35, 67, 89, 11, 99])
total = 0
for i in range(len(arr)):
total = total + arr[i]
avg = total / len(arr)
print('\nThe Sum Of Array Elements = ', total)
print('\nThe Average Of Array Elements = ', avg)The Sum Of Array Elements = 340
The Average Of Array Elements = 48.57142857142857使用 while 循环计算数组平均值的 Python 程序
import numpy as np
arr = np.random.randint(10, 150, size = 11)
print('The Random Array Genegrated')
print(arr)
total = 0
i = 0
while i < len(arr):
total = total + arr[i]
i = i + 1
avg = total / len(arr)
print('\nThe Sum Of Array Elements = ', total)
print('\nThe Average Of Array Elements = ', avg)The Random Array Genegrated
[123 91 119 131 45 121 48 53 44 60 82]
The Sum Of Array Elements = 917
The Average Of Array Elements = 83.36363636363636这个 Python 示例允许输入数组元素，并找到所有数组项的总和和平均值。
import numpy as np
arrlist = []
Number = int(input("Total Array Elements to enter = "))
for i in range(1, Number + 1):
value = int(input("Please enter the %d Array Value = " %i))
arrlist.append(value)
arr = np.array(arrlist)
total = 0
for i in range(len(arr)):
total = total + arr[i]
avg = total / len(arr)
print('\nThe Sum Of Array Elements = ', total)
print('\nThe Average Of Array Elements = ', avg)Total Array Elements to enter = 7
Please enter the 1 Array Value = 22
Please enter the 2 Array Value = 44
Please enter the 3 Array Value = 66
Please enter the 4 Array Value = 88
Please enter the 5 Array Value = 99
Please enter the 6 Array Value = 122
Please enter the 7 Array Value = 154
The Sum Of Array Elements = 595
The Average Of Array Elements = 85.0
