编写一个 Python 程序,使用 for 循环范围(或 i in range(len(posArr))打印数组中的正数。if 条件(if (posArr[i] >= 0))检查 numpy 数组项是否大于或等于零。如果为真,则打印正数组项。
# Print Positives in Array
import numpy as np
posArr = np.array([10, -22, -14, 19, 11, -9, 0])
print("**The Positive Numbers in this posArr Array***")
for i in range(len(posArr)):
if (posArr[i] >= 0):
print(posArr[i], end = " ")
**The Positive Numbers in this posArr Array***
10 19 11 0
使用 for 循环打印数组中正数的 Python 程序
在这个 Python 示例中,for 循环(posArr 中的 num)迭代原始值。在第二个 for 循环中,numpy greater_equal 函数(if (np.greater_equal(i,0)= True))检查 numpy 数组项是否大于或等于零并返回 True。如果为真,则打印 numpy 数组中的正数。
# Print Positive in Array
import numpy as np
posArr = np.array([1, 22, -99, -4, 14, 11, -10])
print("**The Positive Numbers in this posArr Array***")
for num in posArr:
if (num >= 0):
print(num, end = " ")
print("\n\n=== Using greater equal function===")
print("**The Positive Numbers in this posArr Array***")
for i in posArr:
if (np.greater_equal(i, 0) == True):
print(i, end = " ")
**The Positive Numbers in this posArr Array***
1 22 14 11
=== Using greater equal function===
**The Positive Numbers in this posArr Array***
1 22 14 11
Python 程序使用 while 循环返回 Numpy 数组中的正数。
# Print Positive in Array
import numpy as np
posArr = np.array([4, -5, 22, -9, -48, 11, 14])
i = 0
print("**The Positive Numbers in this posArr Array***")
while (i < len(posArr)):
if (np.greater_equal(posArr[i], 0) == True):
print(posArr[i], end = " ")
i = i + 1
**The Positive Numbers in this posArr Array***
4 22 11 14
在这个 Python numpy 数组示例中,我们创建了一个(def printppositivennumbers(posArr))函数来打印正数。
# Print Positive in Array
import numpy as np
def printPositiveNumbers(posArr):
for i in posArr:
if (np.greater_equal(i, 0) == True):
print(i, end = " ")
posArr = np.array([1, -11, 0, 15, -9, -17, 22, -67, 55])
print("**The Positive Numbers in this posArr Array***")
printPositiveNumbers(posArr)
