創(chuàng)新互聯(lián)Python教程：

站在用戶(hù)的角度思考問(wèn)題，與客戶(hù)深入溝通，找到威遠(yuǎn)網(wǎng)站設(shè)計(jì)與威遠(yuǎn)網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗(yàn)，讓設(shè)計(jì)與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個(gè)性化、用戶(hù)體驗(yàn)好的作品，建站類(lèi)型包括：做網(wǎng)站、成都網(wǎng)站制作、企業(yè)官網(wǎng)、英文網(wǎng)站、手機(jī)端網(wǎng)站、網(wǎng)站推廣、域名注冊(cè)、網(wǎng)絡(luò)空間、企業(yè)郵箱。業(yè)務(wù)覆蓋威遠(yuǎn)地區(qū)。

編寫(xiě)一個(gè) Python 程序，將列表向左旋轉(zhuǎn) n 次或N個(gè)位置。在這個(gè) Python 示例中，我們使用位置對(duì)列表進(jìn)行切片，并使用算術(shù)+對(duì)其進(jìn)行組合。

ltList = [5, 10, 15, 20, 25, 30, 35, 40, 45, 50]

ltRotate = int(input("Enter Position to Left Rotate List Items = "))

print('Original List Items Before Left Rotating')
print(ltList)

list2 = ltList[ltRotate:] + ltList[:ltRotate]

print('\nFinal List Items After Left Rotating')
print(list2)

這個(gè) Python 程序使用 for 循環(huán)按照用戶(hù)給定的位置向左旋轉(zhuǎn)列表元素。

ltList = [11, 22, 33, 44, 55, 66, 77, 88]

ltRotate = int(input("Enter Position to Left Rotate List Items = "))

print('Original List Items Before Left Rotating')
print(ltList)

for i in range(ltRotate):
    firstValue = ltList[0]
    for j in range(len(ltList) - 1):
        ltList[j] = ltList[j + 1]
    ltList[len(ltList) - 1] = firstValue

print('Final List Items After Left Rotating')
print(ltList)

Enter Position to Left Rotate List Items = 6
Original List Items Before Left Rotating
[11, 22, 33, 44, 55, 66, 77, 88]
Final List Items After Left Rotating
[77, 88, 11, 22, 33, 44, 55, 66]

本 Python 示例允許用戶(hù)輸入列表大小、項(xiàng)目、旋轉(zhuǎn)編號(hào)，并將列表項(xiàng)目向左旋轉(zhuǎn)給定的編號(hào)。

def printListItems(ltList):
    for i in range(len(ltList)):
        print(ltList[i], end = '   ')

ltList = []
ltListTot = int(input("Total Number of Left Rotate List Items = "))

for i in range(1, ltListTot + 1):
    ltListvalue = int(input("Please enter the %d List Item = "  %i))
    ltList.append(ltListvalue)

ltRotate = int(input("Enter Position to Left Rotate List Items = "))

print('\nOriginal List Items Before Left Rotating')
printListItems(ltList)

for i in range(ltRotate):
    firstValue = ltList[0]
    for j in range(len(ltList) - 1):
        ltList[j] = ltList[j + 1]
    ltList[len(ltList) - 1] = firstValue

print('\nFinal List Items After Left Rotating')
printListItems(ltList)

Total Number of Left Rotate List Items = 7
Please enter the 1 List Item = 30
Please enter the 2 List Item = 40
Please enter the 3 List Item = 50
Please enter the 4 List Item = 70
Please enter the 5 List Item = 90
Please enter the 6 List Item = 120
Please enter the 7 List Item = 180
Enter Position to Left Rotate List Items = 2

Original List Items Before Left Rotating
30   40   50   70   90   120   180   
Final List Items After Left Rotating
50   70   90   120   180   30   40 

Python 程序使用 while 循環(huán)向左旋轉(zhuǎn)列表 n 次。

def printListItems(ltList):
    i = 0
    while i < len(ltList):
        print(ltList[i], end = '   ')
        i = i + 1

ltList = []
ltListTot = int(input("Total Number of Left Rotate List Items = "))
i = 1
while i <= ltListTot:
    ltListvalue = int(input("Please enter the %d List Item = "  %i))
    ltList.append(ltListvalue)
    i = i + 1

ltRotate = int(input("Enter Position to Left Rotate List Items = "))

print('\nOriginal List Items Before Left Rotating')
printListItems(ltList)

i = 0
while i < ltRotate:
    firstValue = ltList[0]
    j = 0
    while j < len(ltList) - 1:
        ltList[j] = ltList[j + 1]
        j = j + 1
    i = i + 1
    ltList[len(ltList) - 1] = firstValue 

print('\nFinal List Items After Left Rotating')
printListItems(ltList)

Total Number of Left Rotate List Items = 8
Please enter the 1 List Item = 23
Please enter the 2 List Item = 45
Please enter the 3 List Item = 67
Please enter the 4 List Item = 98
Please enter the 5 List Item = 89
Please enter the 6 List Item = 11
Please enter the 7 List Item = 16
Please enter the 8 List Item = 87
Enter Position to Left Rotate List Items = 3

Original List Items Before Left Rotating
23   45   67   98   89   11   16   87   
Final List Items After Left Rotating
98   89   11   16   87   23   45   67
