Question

关于Python的几个问题，答案通过电脑运行之后就会采纳，谢谢大家了

Answer 1

1.
s = input(">>>")
result = ' '.join([i.lower()[1:] + i[0].lower() +'ay' for i in s.split()])
print(result)
2.
s = input(">>>")

for i in s.split() :
    if i[0] == 'b':
        print(i)

3.
s = input(">>>")

for i in s.split() :
    if i[-2:] == 'ed':
        print(i)
4.
def getR(l):
    return sorted(set(l))

s = input(">>>")

res = getR(list(map(int, s.split())))
print(res)

5.
s = input(">>>")

d = {'ABC': '2',
     'DEF': '3',
     'GHI': '4', 
     'JKL': '5',
     'MNO': '6',
     'PRS': '7',
     'TUV': '8',
     'WXY': '9',
     }
res = [[v for k, v in d.items() if i in k] for i in s]
res = ''.join(i[0] for i in res)
print(res)
6.
def getR(s):
    return s.lower() == s.lower()[::-1]

s = input(">>>")
print(getR(s))

用列表模拟栈
def is_palindrome(s):
    s = s.lower()
    l = []
    for i in s:
        l.append(i)
    s1 = ''
    while l:        
        s1 += l.pop()
    return s == s1

s = input(">>>")
print(is_palindrome(s))
