转换字符串列表到元组?

Question

我正在尝试使用。txt文件为我的游戏制作排行榜功能，但当提取列表时，它将元组转换为字符串

我的代码:

#USER INPUT__________________________________________________________
text=input("input: ")
#READING AND PRINTING FILE__________________________________________
a_file = open("textest.txt", "r")
list_of_lists = []
for line in a_file:
stripped_line = line.strip()
line_list = stripped_line.split()
list_of_lists.append(line_list)
a_file.close()
print(list_of_lists)
#INSERTING STUFF IN THE FILE_________________________________________
with open("textest.txt", "a+") as file_object:
file_object.seek(0)
data = file_object.read(100)
if len(data) > 0 :
file_object.write("n")
file_object.write(text)

文件的内容是

['test1', 60]
['play 1', 5080] 
['test2', 60]
['test3', 160]
['fake1', 69420]

，但输出给出("['test1', 60]","['play 1', 5080]","['test2', 60]","['test3', 160]","['fake1', 69420]")

Answer 1

ast.literal_eval()安全地求值表达式节点或包含Python文字的字符串。

import ast
data = ("['test1', 60]","['play 1', 5080]","['test2', 60]","['test3', 160]","['fake1', 69420]")
[tuple(ast.literal_eval(x)) for x in data]

输出:

[('test1', 60),
('play 1', 5080),
('test2', 60),
('test3', 160),
('fake1', 69420)]

Answer 2

使用ast.literal_eval()将文件解析为列表

import ast
with open("textest.txt", "r") as a_file:
list_of_lists = [ast.literal_eval(line) for line in a_file]
