Python:用另一个列表替换一个列表?
我卡住了。我正在将网络上所有具有唯一ID的文件夹移动到中心位置。有几个文件夹有输入错误,因此与中心位置的唯一ID不匹配。我找到了正确的ID,但我需要在移动这些文件夹之前重命名它们。例如,我用错误的唯一ID创建了一个excel电子表格,并且在另一列中使用了正确的ID。现在,我想用正确的ID重命名文件夹,然后将这些文件夹转移到中心位置。我的代码很粗糙,因为我想不出一个好的方法。我觉得使用列表是一种方法,但是由于我的代码是在一个文件夹中迭代的,所以我不确定如何实现这一点 编辑:我想类似的东西可能就是我想要的 例: 在文件夹A中:名为12334的文件应重命名为1234。然后移动到文件夹1234中的基本目录 这是我的密码:Python:用另一个列表替换一个列表?,python,list,rename,Python,List,Rename,我卡住了。我正在将网络上所有具有唯一ID的文件夹移动到中心位置。有几个文件夹有输入错误,因此与中心位置的唯一ID不匹配。我找到了正确的ID,但我需要在移动这些文件夹之前重命名它们。例如,我用错误的唯一ID创建了一个excel电子表格,并且在另一列中使用了正确的ID。现在,我想用正确的ID重命名文件夹,然后将这些文件夹转移到中心位置。我的代码很粗糙,因为我想不出一个好的方法。我觉得使用列表是一种方法,但是由于我的代码是在一个文件夹中迭代的,所以我不确定如何实现这一点 编辑:我想类似的东西可能就是我

感谢下面的答案,这是我的最终代码:

basedir = r"C:\Links"
subfolder = "\Private Drain Connections"

l = ['372911000002001',

l2 = ['372911000003100',

try:
#Walk through all files in the directory that contains the files to copy
for root, dirs, files in os.walk(movdir):
for filename in files:
#find the name location and name of files
path = os.path.join(root, filename)
#file name and extension
ARN, extension = os.path.splitext(filename)
oldname = str(ARN)

link = os.path.join(basedir, ARN)
if not os.path.exists(link):
for ii, jj in zip(l, l2):
newname = re.sub(ii,jj, ARN)
newname = str(newname)
print path
newpath = os.path.join(root, oldname) + extension
print "new name", newpath
os.rename(path, newpath)
print "Renaming"
newpath2 = basedir + "\\" + newname + subfolder
shutil.copy(newpath, newpath2)
print "Copied"
if newname != ARN:
break
else:
continue
except:
print ("Error occurred")
tb = sys.exc_info()[2]
tbinfo = traceback.format_tb(tb)[0]
pymsg = "PYTHON ERRORS:\nTraceback Info:\n" + tbinfo + "\nError Info:\n " + \
str(sys.exc_type)+ ": " + str(sys.exc_value) + "\n"
msgs = "GP ERRORS:\n" + arcpy.GetMessages(2 )+ "\n"
print (pymsg)
print (msgs)
想法:尝试将id转换为字符串。我的意思是:
newname = re.sub('372911000002001','372911000003100',ARN)
希望有帮助 对我来说,方法是将两个列表读入列表对象:
list1 = ["372911000002001", "372809000001400", "372809000001500"]
list2 = ["372911000003100", "372909000001400", "372909000001500"]
for ii, jj in zip(list1, list2):
newname = re.sub(ii,jj,ARN) #re.sub returns ARN if no substitution done
if newname != ARN:
break
那是。。。不仅仅是替换一个列表…@IgnacioVazquez Abrams我已经完成了代码的另一部分,我需要一种更有效的方法来替换坏名字。高效还是优雅?我们讨论了多少错误的文件夹?@Jblasco目前只有30个,我认为效率不是问题。。。我认为优雅是第一位的;)
