sorry i didnt write everything. the init method also had...
self.filename = filename ... i will paste the whole code

@ DAVE.. you said
sys is a module (presumably you have an import
somewhere above this line). In the module, there's a list argv.
the import statements are:
import sys
import os
import shutil
import zipfile
so im guessing [sys, os, shutil, zipfile] these are the arguments being
passed? my mind tells me no, as these are more likely the arguments in the
A_Class init method?
here is he full code... i changed the names in the mail to make it clearer.
so the names in the code will be different. A_Class is actually ZipReplace
etc..
i cant test it because on start the program returns this error and i dont
know how to fix it:
ZipReplace(*sys.argv[1:4]).zip_find_replace()
TypeError: __init__() takes exactly 4 positional arguments (1 given)
full code:
import sys
import os
import shutil
import zipfile
class ZipReplace:
def __init__(self, filename, search_string, replace_string):
self.filename = filename
self.search_string = search_string
self.replace_string = replace_string
self.temp_directory = "unzipped-{}".format(
filename)
def _full_filename(self, filename):
return os.path.join(self.temp_directory, filename)
def zip_find_replace(self):
self.unzip_files()
self.find_replace()
self.zip_files()
def unzip_files(self):
os.mkdir(self.temp_directory)
zip = zipfile.ZipFile(self.filename)
try:
zip.extractall(self.temp_directory)
finally:
zip.close()
def find_replace(self):
for filename in os.listdir(self.temp_directory):
with open(self._full_filename(filename)) as file:
contents = file.read()
contents = contents.replace(
self.search_string, self.replace_string)
with open(self._full_filename(filename), "w") as file:
file.write(contents)
def zip_files(self):
file = zipfile.ZipFile(self.filename, 'w')
for filename in os.listdir(self.temp_directory):
file.write(self._full_filename(filename), filename)
shutil.rmtree(self.temp_directory)
if __name__ == "__main__":
ZipReplace(*sys.argv[1:4]).zip_find_replace()
is a bit too advanced for me but i now see what it does.. although i wish
it didnt return an error when run.
so the arguments being passed are...
[os, shutil, zipfile] or [filename, search_string, return_string] ?
