字符串到列表和列表到字符串的转换 - 没有拆分

Question

Could you share how to convert string to list and vice versa as shown below (without splitting each words)

• Input: string 'I am a boy'
• Output: ['I am a boy']

and

• Input: list ['I am a boy']
• Output: string 'I am a boy'

Just to be clear, The first part is pretty straightforward and did implemented before the post. I just stuck for the 2nd problem.

Answer 1

To "convert" a string to a list, you can just place it in one, eg, by creating a new list with [] :

input1 = 'I am a boy'
output1 = [input1]

To "convert" a list like you have to a string, you could simply extract the first and only value in it:

input2 = ['I am a boy']
output2 = input2[0]

Answer 2

String to list (supposing it's a list with just 1 string, as per your image)

inp = 'I am a boy'
lst = [input]

List to string (supposing it's a list with just 1 element of type string)

inp = ['I am a boy']
string = input[0]

If you want to force casting (maybe cause you have a list of integers), you can use the str() function, such as str(inp[0]) where inp[0] is maybe a number
