如何拆分包含多个列表的字符串？ python

Question

Hi Im having trouble while reading a file and trying to split a string that has 2 lists.

I have this string in the file text:

BaseDeDatos.txt:

hello test, C, ['Gore', 'Family'], 3.4, Actor, ['Cesar', 'Mile'], 1

Code:

with open('BaseDeDatos.txt', 'r') as data:
        peli = data.readlines()[int(modificar_peli)-1]
        selec_final = [ast.literal_eval(i) if i.startswith('[') else int(i) if re.findall('^\\d+$', i) else i for i in re.split(',\s*', peli)]

As suggested from another question: question I tried using ast.literal_eval() but im getting this error:

return compile(source, filename, mode, flags,  File "<unknown>", line 1
    ['Gore'
          ^
SyntaxError: unexpected EOF while parsing

Output Expected:

["hello test", "C", "['Gore', 'Family']", "3.4", "Actor", "['Cesar', 'Mile']", "1"] 

If it helps I tried using the same code when I had only 1 list and it split it perfectly.

Any help is appreciated:)

Answer 1

s = "hello test, C, ['Gore', 'Family'], 3.4, Actor, ['Cesar', 'Mile'], 1"

splitted = re.split(r', (?!\')', s)

This will split the line on , (comma and space) only if there is no single-quote ' after slit expression. More about lookahead syntax: https://docs.python.org/3/library/re.html#index-21

Output:

['hello test',
 'C',
 "['Gore', 'Family']",
 '3.4',
 'Actor',
 "['Cesar', 'Mile']",
 '1']

Answer 2

I think it will help your problem.

Basetext = open("LAB3.txt", "r")
listfortext = []
for line in Basetext:
    listfortext.append(line.split())
Basetext.close()
