问题
I need to convert a list into a string and then do the reverse process. Note that one script will convert List->String and another script will convert String->List, so store the list in a variable is not a solution. Use split(', ') or similar is not a solution either in all cases. So, as a challange I invite you to do the conversion in the following example:
l = ['ab,.cd\'ac"', b'\x80', '\r\nHi, !', b'\x01']
str_l = str(l)
I have tried one thing that worked: using exec() built-in function but people says is not a good practice, so I invite you to give me another alternative. Also I am having problems using exec() inside a function but that's another question that you can check -> Using exec() inside a function Python 3
回答1:
This should work:
str_l = ("|").join(l)
Which gives you your first string. Then do:
l_2 = str_l.split("|")
Which gives you your second list.
