win10/win7系统下无法重命名和打开文件提示文件名太长怎么解决
这里分享一段python代码批量修改文件名字：
import os,sys,re
mydir=os.path.abspath(sys.argv[1])
os.chdir(mydir)
cwd = os.getcwd()
#group ID map
id={"A79_A103_A104_A246_A356_A357_A375_A378_A379_A381_vs_A37_A409_A5_A48_A32_A221_A41_A241_A406_A408":"CW_vs_AW",
"A11_A12_A13_A19_A201_A211_A271_A303_A314_A315_A316_A318_A319_A325_A329_A337_A341_A344_A346_A349_A351_A360_A370_vs_A5_A32_A37_A41_A48_A79_A103_A104_A221_A241_A246_A356_A357_A375_A378_A379_A381_A406_A408_A409":"C_vs_W"
}
i=0
for dir_path, dir_names, file_names in os.walk(cwd):
for file_name in file_names:
p=os.path.join(dir_path,file_name)
if len(file_name)>100:
m=re.match(r'(.+_vs_[^\.]+)', file_name)
vs=m.group(1)
if(id.has_key(vs)):
newfilename=re.sub(r'^[^\.]+_vs_[^\.]+\.', "%s."%str(id[vs]), file_name)
os.system("mv %s %s"%(p,os.path.join(dir_path,newfilename)))
print(os.path.basename(p)+"\t"+newfilename)
else:
i=i+1
id[vs]="DEG%s"%i
newfilename=re.sub(r'^[^\.]+_vs_[^\.]+\.', "%s."%str(id[vs]), file_name)
os.system("mv %s %s"%(p,os.path.join(dir_path,newfilename)))
print(os.path.basename(p)+"\t"+newfilename)
