自动更改python文件并用不同的文件名保存

Question

我有一个名为^{的python文件

it has some code in which, i just have to change a word "file_1" to "file_2"

并保留其他函数的缩进

^{pr2}$

word file_1有3次出现

^{3}$

有什么方法可以自动化吗？在

Answer 1

创建脚本：

第一：读取文件

with open("./file1.py") as f:
    content = f.read()

第二个：替换文件名

^{pr2}$

第三：写新文件（我建议你写一个新文件）

with open("./file2.py", "w") as f:
    f.write(new_content)

如果您有多个文件，请使用类似

filenames = ["file" + str(item) for item in range(1,100)]
for filename in filenames:
    with open(filename + ".py") as f:
        content = f.read()
    new_filename = filename[:-1] + str(int(filename[-1]) + 1)
    new_content = content.replace(filename,new_filename)
    with open("./another_folder" + new_filename + ".py", "w") as f:
        f.write(new_content)

Answer 2

运行此脚本：

import fileinput

with fileinput.FileInput('file_1.py', inplace=True, backup='.bak') as file:
    for line in file:
        print(line.replace('file_1', 'file_2'), end='')
