Question

我想比较n个单词。单词的第一个和最后一个字母必须相同，下一个单词必须从结尾开始，并以字母表中的下一个字母结束。如果所有单词都正确，则打印'ok'。

例如：3利物浦MaM纳尔逊

'OK'

n = int(input("Input a number: "))

woorden = []

for i in range(n):
    woord = input("Enter a string: ")
    woorden.append(woord)
    if woord[:1].startswith('"') == woord[:-1].endswith('"'): 
    if ord(woord[:-1]) == ord(woord[:1]):
        print('ok')
    else:
        print(f'{woord}')

Answer 1

你的if \ else缩进是坏的。只有在检查完循环后的整个项目AKA后才需要进行打印。

n = int(input("Input a number: "))
allGood = True
woorden = []

for i in range(n):
    woord = input("Enter a string: ")
    woorden.append(woord)
    if woord[:1].startswith('"') == woord[:-1].endswith('"'): 
    if ord(woord[:-1]) != ord(woord[:1]):
        allGood = False

print allGood

Answer 2

可能是这样的：

>>> n = int(input("Input a number: "))
Input a number: 3
>>> woorden = []
>>> for i in range(n):
        word = raw_input('Enter a string: ')
        woorden.append(word)
        if word[0] != word[-1]:
            break
        if i==0:
            previous_char = ord(word[0].lower())
            continue
        if ord(word[0].lower()) != (previous_char+1):
            break
        previous_char = ord(word[0].lower())
    else:
        print 'Ok'


Enter a string: liverpool
Enter a string: MaM
Enter a string: nelson

Ok

Answer 3

假设这是预期的输出

Input a number: 5
Enter a string: This
Enter a string: test
Enter a string: is
is
Enter a string: true
Enter a string: fine
ok

代码

n = int(input("Input a number: "))
x = []
ok = False
for i in range(0,n):
    woord = input("Enter a string: ")
    if i > 0:
        y = ord(woord[:1].lower()) -96
        z = ord(woord[-1].lower())-96
        x.append(y)
        x.append(z)
        if x[c-1] - y == -1:
            ok = True
        else:
            print(f'{woord}')
            ok = False
        c=c+2
    else:
        x.append(ord(woord[-1].lower())-96)
        c=1
if (ok):
    print('ok')

对于提及的情景

Input a number: 3
Enter a string: liverpool
Enter a string: MaM
Enter a string: nelson
ok

Answer 4

这段代码似乎适用于所有情况但不包含以下字样：＆＃39; Zhanaz＆＃39;其次是艾丽西亚＆＃39;。谁知道如何解决这个问题？

n = int(input("Input a number: "))
    woorden = []

    for i in range(n):
        woord = input("Enter a string: ")
        woorden.append(woord)
        if woord[0].lower() != woord[-1].lower():
            print(f'{woord}')
            break
        if i == 0:
            previous_char = ord(woord[0].lower())
            continue
        if ord(woord[0].lower()) != (previous_char+1):
            print(f'{woord}')
            break
        previous_char = ord(woord[0].lower())

    else:
        print('Ok')
