Python copies specific suffix files and preserves instances of the original directory structure

This article mainly introduces the Python copy specific suffix file, and preserves the original directory structure of the instance, has a certain reference value, now share to everyone, the need for friends can refer to

As shown below:

#!/usr/bin/python#-*-coding:utf-8-*-import osimport shutildef cp_tree_ext ( Exts,src,dest): "" Rebuild the director tree like SRC below dest and copy all files like xxx.exts to Dest Exts:exeten s seperate by blank like "jpg png gif" "" "fp={} extss=exts.lower (). Split () for Dn,dns,fns in Os.walk (SRC): for FL In Fns:if Os.path.splitext (Fl.lower ()) [1][1:] ' extss:if dn not ' in Fp.keys (): fp[dn]=[] fp[      Dn].append (FL) for k,v in Fp.items (): Relativepath=k[len (SRC) + 1:] Newpath=os.path.join (Dest,relativepath) For f in V:oldfile=os.path.join (k,f) print ("Copy [" +oldfile+ "] to [" +newpath+ "]") if not os.path.exists (NewPath): Os.makedirs (NewPath) shutil.copy (Oldfile,newpath) #用法如下: # #cp_tree_ext (exts,src,dest) # #exts: separated by spaces String, can be multiple extension names, such as "Bat txt" #src: Original directory #dest: Target directory, if not present, then establish Cp_tree_ext (' Doc docx ', '/home/lincoln/python/copy/source ', '/ Home/lincoln/python/copy/target ') 

Just a piece of code, call the Cp_tree_ext (Exts,src,dest) method directly.
