We can convert a string to list in Python using split() function.
我们可以使用split（）函数将字符串转换为Python中的列表。
Python String split() function syntax is:
Python字符串split（）函数语法为：
str.split(sep=None, maxsplit=-1)Python将字符串转换为列表 (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.
让我们看一个简单的示例，在此示例中，我们要将字符串转换为单词列表，即使用分隔符将其分割为空白。
s = 'Welcome To JournalDev'
print(f'List of Words ={s.split()}')Output: List of Words =['Welcome', 'To', 'JournalDev']
输出： List of Words =['Welcome', 'To', 'JournalDev']
f-strings in Python
Python中的f字符串
If we want to split a string to list based on whitespaces, then we don’t need to provide any separator to the split() function. Also, any leading and trailing whitespaces are trimmed before the string is split into a list of words. So the output will remain same for string s = ' Welcome To JournalDev ' too.
如果我们想将字符串拆分为基于空格的列表，则无需为split（）函数提供任何分隔符。 同样，在将字符串拆分为单词列表之前，将修剪所有前导和尾随空格。 因此，对于字符串s = ' Welcome To JournalDev ' ，输出也将保持相同。
Let’s look at another example where we have CSV data into a string and we will convert it to the list of items.
让我们看另一个示例，其中将CSV数据转换为字符串，然后将其转换为项目列表。
s = 'Apple,Mango,Banana'
print(f'List of Items in CSV ={s.split(",")}')Output: List of Items in CSV =['Apple', 'Mango', 'Banana']
输出： List of Items in CSV =['Apple', 'Mango', 'Banana']
Python字符串到字符列表 (Python String to List of Characters)
Python String is a sequence of characters. We can convert it to the list of characters using list() built-in function. When converting a string to list of characters, whitespaces are also treated as characters. Also, if there are leading and trailing whitespaces, they are part of the list elements too.
Python字符串是字符序列。 我们可以使用内置的list（）函数将其转换为字符列表 。 将字符串转换为字符列表时，空格也被视为字符。 另外，如果存在前导和尾随空格，它们也属于列表元素。
s = 'abc$ # 321 '
print(f'List of Characters ={list(s)}')Output: List of Characters =['a', 'b', 'c', '$', ' ', '#', ' ', '3', '2', '1', ' ']
输出： List of Characters =['a', 'b', 'c', '$', ' ', '#', ' ', '3', '2', '1', ' ']
If you don’t want the leading and trailing whitespaces to be part of the list, you can use strip() function before converting to the list.
如果您不希望前导和尾随空格成为列表的一部分，则可以在转换为列表之前使用strip（）函数 。
s = ' abc '
print(f'List of Characters ={list(s.strip())}')Output: List of Characters =['a', 'b', 'c']
输出： List of Characters =['a', 'b', 'c']
That’s all for converting a string to list in Python programming.
这就是在Python编程中将字符串转换为列表的全部过程。
