my python script (1) ---------create model script file-优快云博客

本文介绍了一个使用Python编写的简单工具，该工具可以根据用户输入的文件路径自动生成包含基本Python代码的脚本文件。它首先检查并创建指定的目录路径，然后在目标位置创建Python文件，并写入初始化代码。

# my python script (1)

# to create script file

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import os,subprocess,sys

child = subprocess.Popen('which python',stdout = subprocess.PIPE,shell=True)
(pypath,error) = child.communicate()
pypath = pypath.strip('\n')

myfile = raw_input('please input file name (like home/test.py)')
if myfile:
    (path,filename) = os.path.split(myfile)
    if path:
        print 'check dir path ...'
        if os.path.exists(path):
            print 'dir already exists!'
        else:    
            print 'dir: %s does not exist!' % path
            print 'create dir: %s ...' % path
            try:
                os.makedirs(path)
                print 'dir: %s is created successfully!' % path    
            except Exception ,e:
                print 'exception occur while try to create dirs %s' % path
                print e
    else:
        pass
else:
    sys.exit('input is none!')

print 'create script file: %s ...' % filename
try:
    f = open(myfile,'w')
    f.write('#!'+ pypath + '\n')
    f.write('#! -*- coding:utf-8 -*-')
    f.write('\n')
    f.write('\n')
    f.write('if __name__ == '+ "'__main__':\n")
    f.write('    print "hello world!"\n')
    f.close()
    print 'script is created successfully!'
except Exception,e:
    print 'exception occur while try to write file: %s ' % filename
    print e
