我正在尝试创建一个python脚本,它将查看一系列子文件夹并删除空shapefile。我已经成功创建了将删除一个文件夹中的空文件的脚本部分,但是"项目"中有总共70个文件夹。夹。虽然我可以复制并粘贴代码69次,但我确定必须让它查看每个子文件夹并运行每个子文件夹的代码。以下是我到目前为止所拥有的内容。有任何想法吗?我对此非常陌生,我只是编辑了一个现有的代码来实现这一目标。谢谢!
import os
# Set the working directory
os.chdir ("C:/Naview/Platypus/Project")
# Get the list of only files in the current directory
file = filter(os.path.isfile, os.listdir('C:/Naview/Platypus/Project'))
# For each file in directory
for shp in file:
# Get only the files that end in ".shp"
if shp.endswith(".shp"):
# Get the size of the ".shp" file.
# NOTE: The ".dbf" file can vary is size whereas
# the shp & shx are always the same when "empty".
size = os.path.getsize(shp)
print "\nChecking " + shp + "'s file size..."
#If the file size is greater than 100 bytes, leave it alone.
if size > 100:
print "File is " + str(size) + " bytes"
print shp + " will NOT be deleted \n"
#If the file size is equal to 100 bytes, delete it.
if size == 100:
# Convert the int output from (size) to a string.
print "File is " + str(size) + " bytes"
# Get the filename without the extention
base = shp[:-4]
# Remove entire shapefile
print "Removing " + base + ".* \n"
if os.path.exists(base + ".shp"):
os.remove(base + ".shp")
if os.path.exists(base + ".shx"):
os.remove(base + ".shx")
if os.path.exists(base + ".dbf"):
os.remove(base + ".dbf")
if os.path.exists(base + ".prj"):
os.remove(base + ".prj")
if os.path.exists(base + ".sbn"):
os.remove(base + ".sbn")
if os.path.exists(base + ".sbx"):
os.remove(base + ".sbx")
if os.path.exists(base + ".shp.xml"):
os.remove(base + ".shp.xml")

有几种方法可以做到这一点。我是glob
for shp in glob.glob('C:/Naview/Platypus/Project/**/*.shp'):
size = os.path.getsize(shp)
print "\nChecking " + shp + "'s file size..."
#If the file size is greater than 100 bytes, leave it alone.
if size > 100:
print "File is " + str(size) + " bytes"
print shp + " will NOT be deleted \n"
continue
print "Removing", shp, "files"
for file in glob.glob(shp[:-3] + '*'):
print " removing", file
os.remove(file)

学习程序编程的时间:Defining Functions。
将代码放入带路径参数的函数中,并为70个路径中的每个路径调用它:
def delete_empty_shapefiles(path):
# Get the list of only files in the current directory
file = filter(os.path.isfile, os.listdir(path))
...
paths = ['C:/Naview/Platypus/Project', ...]
for path in paths:
delete_empty_shapefiles(path)
创建执行os.path.exists()
和os.remove()
来电的功能的加分点。
