chars=list(input) print(chars)# ['A', 'B', 'C'] 下载运行代码 2. 使用列表理解 另一种方法是使用列表推导。 Python 中经常使用列表推导来构造一个新列表,其中每个列表元素都来自应用于可迭代的每个成员的某些操作。这可以实现为: 1 2 3 4

convert_special_chars()是一个函数,用于将特殊字符转成字符串。 函数接受一个参数text,表示待转换的文本。 函数使用replace()方法将特殊字符转成字符串。 special_chars.items()遍历特殊字符字典中的键值对。 text.replace('\\' + char, escape_char)将text中的特殊字符\加上简写形式char替换成对应的转义字符esc...

字符串的下标索引是从0开始的,所以a_string[0:2]会返回原字符串的前两个元素,从a_string[0]开始,直到但不包括a_string[2]。 如果省略了第一个索引值,Python会默认它的值为0。所以a_string[:18]跟a_string[0:18]的效果是一样的,因为从0开始是被Python默认的。 同样地,如果第2个索引值是原字符串的长...
