## Actual Code:
import zipfile, arcpy, os.path, os
#1 Defining a function to Unzip the initial (.zip) folder. (this worked fine)
def unzip_Orig(oZ):
z = zipfile.ZipFile(oZ)
z.extractall()
return
q = "unzip_Unzip_Data_Test.zip"
unzip_Orig(q)
#2 my attempts to unzip each zipfile within the new folder below
(failed thus far)
mywd = os.getcwd()
zipList = os.listdir(mywd)
print zipList #this didn't work, it printed the directory of where
the .py was stored.
Given the help below for the two os functions you've called, what did
you expect it to do?
>>> help(os.getcwd)
Help on built-in function getcwd in module nt:
getcwd(...)
getcwd() -> path
Return a string representing the current working directory.
>>> help(os.listdir)
Help on built-in function listdir in module nt:
listdir(...)
listdir(path) -> list_of_strings
Return a list containing the names of the entries in the directory.
path: path of directory to list
The list is in arbitrary order. It does not include the special
entries '.' and '..' even if they are present in the directory.
#Zipfile.printdir() # returned "'Zipfile' is not defined.
True indeed, did you mean this to be zipList or what?
#thoughts?
Your assignment for tonight is to go back to the drawing board, let's
face it we wouldn't write code for your students :)
# Thanks
