Python Convert String to List Let’s look at a simple example where we want to convert a string to list of words i.e. split it with the separator as white spaces. s = 'Welcome To JournalDev' print(f'List of Words ={s.split()}') Copy Output: List of Words =['Welcome', 'To...
所以,在此处a_string[18:]跟a_string[18:44]的结果是一样的,因为这个串的刚好有44个字符。这种规则存在某种有趣的对称性。在这个由44个字符组成的串中,a_string[:18]会返回前18个字符,而a_string[18:]则会返回除了前18个字符以外字符串的剩余部分。事实上a_string[:n]总是会返回串的前n个字符,而a_s...

在Python的编程中,经常会涉及到字符串与list之间的转换问题,下面就将两者之间的转换做一个梳理。 1、list转换成字符串 命令:list() 例子: 2、字符串转换成list 命令:"".join(list) 其中,引号中是字符之间的分割符,如“,”,“;”,“\t”等等
