对 txt 文件中的字符串行进行排序，然后用排序后的行覆盖它

Question

基本上我有一个这样的文件：

hi
my
name
is

我希望它是（按字母顺序排序）：

hi
is
my
name

我下面的代码将 txt 文件中的行存储到一个列表中，然后对其进行排序。它可以满足我的要求，但是...:[=13=]

with open ("3ex.txt","r") as f:
    new = []
    for line in f:
        stripped = line.strip("\n")
        new.append(stripped)

    new.sort() #sorts by letter
    print(new)

with open ("3ex.txt","w") as file:
    for k in new:
        file.write(file"[k]\n")

它不会覆盖它。我尝试先读取文件然后写入文件。但我一直收到错误。

是的，我知道这样做很糟糕，但这就是我要求的。

Answer 1

从 with 语句中定义 new 列表。并更正 file.write 参数。这是更正后的代码

new = []
with open ("3ex.txt","r") as f:
    for line in f:
        stripped = line.strip("\n")
        new.append(stripped)

new.sort() #sorts by letter
with open ("3ex.txt","w") as file:
    for k in new:
        file.write(k + "\n")

对 txt 文件中的字符串行进行排序，然后用排序后的行覆盖它
