我喜欢3个字符串，如何删除标点符号并使所有评论变为小写，然后打印出所有3条评论。
Review1 = 'My great auntie has lived at Everton Park for decades, and once upon a time I even lived here too, and I remember the days before when there was nothing remotely hipster about this housing block. It is really cool to see cute new cafes and coffee shops moving in, and I've been to Nylon every time I'm back in town.'
Review2 = 'Solid coffee in the Outram Park neighborhood. Location is hidden in a HDB block so you definitely need to search for it. Minus one star for limited seating options'
Review3 = 'Deserve it, truly deserves this much reviews. I will describe coffee here as honest, sincere, decent, strong, smart.'

import string
Review1_Fixed = Review1.lower().translate(str.maketrans('', '', string.punctuation))
print(Review1_Fixed)
输出：

__contains__方法定义了类实例出现在in运算符右侧而不是in运算符右侧的行为。
from string import ascii_letters
Review1 = "My great auntie has lived at Everton Park for decades, and once upon a time I even lived here too, and I remember the days before when there was nothing remotely hipster about this housing block. It is really cool to see cute new cafes and coffee shops moving in, and I've been to Nylon every time I'm back in town."
key = set(ascii_letters + ' ') # key = set('abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ')
Review1_ = ''.join(filter(key.__contains__, Review1)).lower()
print (Review1_)
输出：

用于删除标点符号
s.translate（无，字符串。标点符号）
或创建自己的功能
def标点（字符串）：
标点符号='''！（）-[] {} ;:'“ \，<> ./?@#$%^&*_〜'''
for x in string.lower():
if x in punctuations:
string = string.replace(x, "")
# Print string without punctuation
print(string)
小写 string.lower（）
