如何从列表中删除标点符号

Question

有人可以帮我写这段代码吗现在我得到的 'test2' 和 'test' 一样，如果我测试的是字符串，它工作正常但作为列表它不能正常工作

 punc = set(string.punctuation)
 test=[" course content good though textbook badly written.not got energy 
 though seems good union.it distance course i'm sure facilities.n/an/ain 
last year offer poor terms academic personal. seems un become overwhelmed trying become run"]

test2 = ''.join(w for w in test if w not in punc)
 print(test2)

我想删除所有标点符号

Answer 1

因为 test 是一个列表，'for w in test' 将 return 列表的第一项，即完整的字符串。因此，您需要访问“w”的所有项目以实际测试字符串的所有单个字符。

Answer 2

import string
test=[" course content good though textbook badly written.not got energy though seems good union.it distance course i'm sure facilities.n/an/ain last year offer poor terms academic personal. seems un become overwhelmed trying become run"]
test2 = ''.join(w for w in test[0] if w not in string.punctuation )
print(test2)

如果列表中有多个字符串

import string
test=["Hi There!"," course content good though textbook badly written.not got energy though seems good union.it distance course i'm sure facilities.n/an/ain last year offer poor terms academic personal. seems un become overwhelmed trying become run"]
#if there are multiple string in the list
for x in test:
    print(''.join(w for w in x if w not in string.punctuation ))
# If there are multiple strings in the list and you want to join all of them togather
print(''.join(w for w in [x for x in test] if w not in string.punctuation ))

如果您需要将其附加到列表变量

import string
test2=[]
test=["Hi There!"," course content good though textbook badly written.not got energy though seems good union.it distance course i'm sure facilities.n/an/ain last year offer poor terms academic personal. seems un become overwhelmed trying become run"]
#if there are multiple string in the list
for x in test:
    test2.append(''.join(w for w in x if w not in string.punctuation ))
print(test2)

Answer 3

最快（也可以说是最 Pythonic 的方式）是使用翻译。

import string
test=["Hi There!"," course content good though textbook badly written.not got energy though seems good union.it distance course i'm sure facilities.n/an/ain last year offer poor terms academic personal. seems un become overwhelmed trying become run"]

# Create a translate table that translates all punctuation to nothing
transtable = {ord(a):None for a in string.punctuation}

# Apply the translation to all strings in the list
[s.translate(transtable) for s in test]
