Python---str.split()[0](第7天)

Python学习：split()方法以及关于str.split()[0]等形式内容的详细讲解：https://blog.csdn.net/qq_41780295/article/details/88555183

几个技术细节

• Linux shell和python的针对路径的语法不同，.py中要表示shell中的根目录‘~/’需要找到具体的位置‘/home/yupengfei/’（例如：），具体位置可以从任意一个文件的属性中看到。
• Linux系统的shell内可以看到所有文件，包括隐藏文件。

上机实践：

批量修改文件名

##rename_py
import os 
#读取文件名称及其路径
def load_file_list(directory):
    
    list = []
    for filename in [y for y in os.listdir(directory) if os.path.isfile(os.path.join(directory,y))]:
        list.append(os.path.join(directory,filename))
    return sorted(list)
qpList=['22','27','32','37']
## 同时修改四个文件夹的文件名
for qp in qpList:
  dir = '/home/yupengfei/HM-16.9/CTC169/CTC_txt/'+qp
  org_file_list =load_file_list(dir)
  print(org_file_list)
  with open('_'+qp+'rename.sh','w') as f:
    for name in org_file_list:
        print(name)
        new_name = name.split('_.txt',1)[0]
        f.write('mv '+name+'\t'+new_name+'.txt')
        f.write('\n')

使用上述脚本生成
