Q2:
源码：
word = input('Enter word: ')
reverse = word[::-1]
if word == reverse:
print('Palindrome? True')
else:
print('Palindrome? False')

运行结果：
>>> ================================ RESTART ================================
>>>
Enter word: racecar
Palindrome? True
>>> ================================ RESTART ================================
>>>
Enter word: research
Palindrome? False
>>>

Q3:
源码：
sentence = input('Type in a line of text: ')string = ''
for each_chr in sentence:
if each_chr.isalpha():
string += each_chr.lower()
print(string)

flag = string == string[::-1]
print('Palindrome?', flag)
运行一下：
>>> ================================ RESTART ================================
>>>
Type in a line of text: Doc, note: I dissent. A fast never prevents a fatness. I diet on cod.
docnoteidissentafastneverpreventsafatnessidietoncod
Palindrome? True
>>> ================================ RESTART ================================
>>>

Palindrome? True
>>> ================================ RESTART ================================
>>>
