we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
1、list.append(obj):在列表末尾添加新的对象 2、list.count(obj):统计某个元素在列表中出现的次数 3、list.extend(seq):在列表末尾一次性追加另一个序列中的多个值(用新列表扩展原来的列表) 4、list.index(obj):从列表中找出某个值第一个匹配项的索引位置 5、list.insert(index, obj):将对象插入列表 6...

字符串和列表可以通过 list, join 方法来进行互转, #list() can convert string to list, #"".join() can convert list to string, #and remove the empty char at the begining and the end of the word word = 'good' wordlist = list(word) ...
1s.translate(str.maketrans('', '', string.punctuation)) 它使用一个查找表在C中执行原始字符串操作——除了编写自己的C代码,没有什么比这更好的了。 如果速度不是问题,另一个选择是: exclude = set(string.punctuation) s = ''.join(ch for ch in s if ch not in exclude) ...

Therefore, the above two snippets result in an empty list. To get ["wtf"] from the generator some_func we need to catch the StopIteration exception, try: next(some_func(3)) except StopIteration as e: some_string = e.value >>> some_string ["wtf"]...
