編寫一個 Python 程序，使用 for 循環(huán)范圍來計算元組中的正數和負數。if 條件(if (posngTuple[i] >= 0))檢查元組項是否大于或等于零。如果為真，我們向正元組計數添加一個；否則(tNegativeCount = tNegativeCount+1)，在負元組計數值上加 1。

# Count Positive and Negative Numbers

posngTuple = (3, -22, -44, 19, -99, -37, 4, 11, -89)
print("Positive and Negative Tuple Items = ", posngTuple)

tPositiveCount = tNegativeCount = 0

for i in range(len(posngTuple)):
    if (posngTuple[i] >= 0):
        tPositiveCount = tPositiveCount + 1
    else:
        tNegativeCount = tNegativeCount + 1

print("The Count of Positive Numbers in posngTuple = ", tPositiveCount)
print("The Count of Negative Numbers in posngTuple = ", tNegativeCount)

計算元組中正數和負數的 Python 程序

在這個 Python 正負示例中，我們使用 for 循環(huán)(對于 posngTuple 中的 pntup)來迭代實際的元組值，并檢查它們是否大于或等于零。

# Count Positive and Negative Numbers

posngTuple = (55, -99, -88, 0, -78, 22, 4, -66, 21, 33)
print("Positive and Negative Tuple Items = ", posngTuple)

tPositiveCount = tNegativeCount = 0
for pntup in posngTuple:
    if(pntup >= 0):
        tPositiveCount = tPositiveCount + 1
    else:
        tNegativeCount = tNegativeCount + 1

print("The Count of Positive Numbers in posngTuple = ", tPositiveCount)
print("The Count of Negative Numbers in posngTuple = ", tNegativeCount)

Positive and Negative Tuple Items =  (55, -99, -88, 0, -78, 22, 4, -66, 21, 33)
The Count of Positive Numbers in posngTuple =  6
The Count of Negative Numbers in posngTuple =  4

Python 程序使用 While 循環(huán)計算元組中的正數和負數。

# Count of Tuple Positive and Negative Numbers

posngTuple = (11, -22, -33, 44, 55, -66, -77, 0, -99)
print("Positive and Negative Tuple Items = ", posngTuple)

tPositiveCount = tNegativeCount = 0
i = 0

while (i < len(posngTuple)):
    if(posngTuple[i] >= 0):
        tPositiveCount = tPositiveCount + 1
    else:
        tNegativeCount = tNegativeCount + 1
    i = i + 1

print("The Count of Positive Numbers in posngTuple = ", tPositiveCount)
print("The Count of Negative Numbers in posngTuple = ", tNegativeCount)

Positive and Negative Tuple Items =  (11, -22, -33, 44, 55, -66, -77, 0, -99)
The Count of Positive Numbers in posngTuple =  4
The Count of Negative Numbers in posngTuple =  5

在這個 Python Tuple 示例中，我們創(chuàng)建了一個返回正數和負數計數的函數。

# Count of Tuple Positive and Negative Numbers

def CountOfPositiveNegativeNumbers(evodTuple):
    tPositiveCount = tNegativeCount = 0
    for pntup in evodTuple:
        if(pntup >= 0):
            tPositiveCount = tPositiveCount + 1
        else:
            tNegativeCount = tNegativeCount + 1
    return tPositiveCount, tNegativeCount

evodTuple = (26, -77, -99, 75, 14, -56, 19, 81, -1, 33) 
print("Positive and Negative Tuple Items = ", evodTuple)

PositiveCount, NegativeCount = CountOfPositiveNegativeNumbers(evodTuple)
print("The Count of Positive Numbers in evodTuple = ", PositiveCount)
print("The Count of Negative Numbers in evodTuple = ", NegativeCount)

Positive and Negative Tuple Items =  (26, -77, -99, 75, 14, -56, 19, 81, -1, 33)
The Count of Positive Numbers in evodTuple =  6
The Count of Negative Numbers in evodTuple =  4
