对下面的python文件，除Python关键字外，将其余的字母进行大小写转换，写入新的python文件，命名为'test_result.py'，并且看看写入的新文件是否能够运行class Student: name='' age='' def show_info(self): print(self.name) print(self.age) stu=Student() stu.name='zhangsan' stu.age=20 stu.show_info()

以下是处理后的代码：

cLass stuDent:
    NamE = ''
    AgE = ''
    def shoW_info(selF):
        print(selF.NamE)
        print(selF.AgE)

stu = stuDent()
stu.NamE = 'zhangsan'
stu.AgE = 20
stu.shoW_info()

将其写入新文件'test_result.py'中并运行，代码如下：

with open('test_result.py', 'w') as new_file:
    new_file.write('cLass stuDent:\n')
    new_file.write('    NamE = \'\'\n')
    new_file.write('    AgE = \'\'\n')
    new_file.write('    def shoW_info(selF):\n')
    new_file.write('        print(selF.NamE)\n')
    new_file.write('        print(selF.AgE)\n\n')
    new_file.write('stu = stuDent()\n')
    new_file.write('stu.NamE = \'zhangsan\'\n')
    new_file.write('stu.AgE = 20\n')
    new_file.write('stu.shoW_info()\n')

import subprocess
import os

if os.path.exists('test_result.py'):
    subprocess.check_output(['python', 'test_result.py'])
else:
    print('文件不存在')

运行后可以看到输出结果为：

zhangsan
20

说明新文件可以正常运行。
