Extracting a zipfile to memory?
extractall extracts to the file system, so you won't get what you want. To extract a file in memory, use the ZipFile.read() method.
If you really need the full content in memory, you could do something like:
def extract_zip(input_zip): input_zip=ZipFile(input_zip) return {name: input_zip.read(name) for name in input_zip.namelist()}
If you work with in-memory archives frequently, I would recommend making a tool. Something like this:
# Works in Python 2 and 3.try: import BytesIOexcept ImportError: from io import BytesIO # Python 3import zipfileclass InMemoryZip(object): def __init__(self): # Create the in-memory file-like object for working w/IMZ self.in_memory_zip = BytesIO() # Just zip it, zip it def append(self, filename_in_zip, file_contents): # Appends a file with name filename_in_zip and contents of # file_contents to the in-memory zip. # Get a handle to the in-memory zip in append mode zf = zipfile.ZipFile(self.in_memory_zip, "a", zipfile.ZIP_DEFLATED, False) # Write the file to the in-memory zip zf.writestr(filename_in_zip, file_contents) # Mark the files as having been created on Windows so that # Unix permissions are not inferred as 0000 for zfile in zf.filelist: zfile.create_system = 0 return self def read(self): # Returns a string with the contents of the in-memory zip. self.in_memory_zip.seek(0) return self.in_memory_zip.read() # Zip it, zip it, zip it def writetofile(self, filename): # Writes the in-memory zip to a physical file. with open(filename, "wb") as file: file.write(self.read())if __name__ == "__main__": # Run a test imz = InMemoryZip() imz.append("testfile.txt", "Make a test").append("testfile2.txt", "And another one") imz.writetofile("testfile.zip") print("testfile.zip created")
