Question

我想使用以下数据导入.txt文件：

no
a
no
a
b
c
no

将其更改为列表（或其他一些数据类型）：

mylist = ["no", "yes", "no", "yes", "yes", "yes", "no"]

并将其保存到新的.txt文件中

到目前为止我想出了什么：

with open("input.txt", "r") as my_file, open("output.txt", "w") as outfile:
    for line in my_file:
        words = line.split()

        for n, i in enumerate(words):
            if i != "no":
                words[n] = "yes"
                i == words[n]

                outfile.write(i + "\n")

因此，我想要一个包含以下数据的文件：

no
yes
no
yes
yes
yes
no

Answer 1

my_file.txt

no
a
no
a
b
c
no

码

with open('my_file.txt', 'r', encoding='utf8') as f:
    text = f.read()

with open('outfile.txt', 'w', encoding='utf8') as f:
    f.write('\n'.join([i if i == 'no' else 'yes' for i in text.split('\n')]))

outfile.txt

no
yes
no
yes
yes
yes
no

有时候，在个别步骤中更容易做事。

更改文件并将其保存到另一个文件（python）
