Python备份目录及目录下的全部内容的实现方法
本来是想写一个东西可以直接调用TortoiseSVN保存当前代码到一个分枝下的。
可惜调用SVN的部分还在研究。就先写了目录拷贝的部分。
如果有喜欢研究Python的童鞋愿意提供想法或者建议的话，
这里先谢谢了。 ：）
就目录拷贝的部分，思想很简单。读配置文件中的配置信息。
生成一个项目名称加日期时间组成的文件夹名为分枝名称。把当前项目下的全部内容
拷贝到这个目录下。
然后要做的研究就是调用TortoiseSVN命令嵌入这部分代码。
现在看代码：
1. 读取配置文件
配置文件很简单。用的就是txt文件。 格式类似于：
# root:/Users/lichallenger/test_src/ # project:test # destination:/Users/lichallenger/test_dst/
BTW: 我用的是Mac所以目录格式是这样的。如果你用的是Windows的话请适
当修改配置文件。
读文件就是最简单的了。直接用标准库的文件操作模块打开文件，读出全部的配置。一共就三行，所以
也不用考虑效率什么的了。
# open config file and read config information
# author: bruce li
class ConfigHandler(object):
#
def __init__(self,config_path):
'''initializer'''
self.config_path = config_path
#read config infor
def read_config(self):
f = open(self.config_path)
try:
self.all_lines = f.readlines()
except:
raise
else:
f.close() 2. 拷贝目录和目录内容
拷贝目录用了shutil模块。里面有个方法可以直接把目录和目录下的全部内容拷贝到制定的其他目录。
这样就省得搞目录遍历之类的代码了。
# copy dir(s) & file(s) to configured path
# author: bruce li
import shutil
class CopyHandler(object):
#
def __init__(self,src_path,dest_path):
self.src_path = src_path
self.dest_path = dest_path
def move_content(self):
try:
shutil.copytree(self.src_path,self.dest_path)
except:
raise
@staticmethod
def move_src_content(src, dest):
try:
shutil.copytree(src_path,dest_path)
except:
raise3. 综合调用
这里用了time模块获取当前时间，然后生成目标文件夹名称的一部分。
外界给python传的系统参数的第一个是文件名。这个文件就相当于C＃项目里的Program文件一样，
里面会包含一个main函数。虽然这个函数不一定要命名为main。
还有注意下，Python代码的换行符为\。
# main of dir copy function
import sys
import time
from code_bk_cpy import *
from code_bk_config import *
#print __name__
def main():
config_path = sys.argv[1]
# check if path of configuration path is empty
if (not config_path):
print 'configuration information is needed'
return -1
config_handler = ConfigHandler(config_path)
config_handler.read_config()
config_list = config_handler.all_lines
if len(config_list) != 3:
print 'configuration information is not correct'
return -1
# set source
sep = ':'
current_datetime = time.localtime(time.time())
root_path = config_list[0].split(sep)[1]
prj_name = config_list[1].split(sep)[1]
dst_path = config_list[2].split(sep)[1]
root_path = (root_path + prj_name).replace('\n','')
prj_folder = prj_name + str(current_datetime.tm_year) + str(current_datetime.tm_mon) + \
str(current_datetime.tm_mday) + str(current_datetime.tm_hour) + \
str(current_datetime.tm_min) + str(current_datetime.tm_sec)
dst_path = (dst_path + '/' + prj_folder + '/').replace('\n','')
copy_handler = CopyHandler(root_path,dst_path)
copy_handler.move_content()
print 'content moved'
# start main function
print __name__
if __name__ == "__main__":
main()有时间我会研究下TortoiseSVN调用那块的东西。估计不会难，就是调用exe传参的问题。
本人初学Python，如有问题敬请指正！谢谢。
以上这篇Python备份目录及目录下的全部内容的实现方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。

Is the vscode extension malicious?
Apr 15, 2025 pm 07:57 PM
VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.
How to run programs in terminal vscode
Apr 15, 2025 pm 06:42 PM
In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.
Can vs code run in Windows 8
Apr 15, 2025 pm 07:24 PM
VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.
