Hello! The code above doesnt delete the .pdf files with send2trash.
Files seems to be closed, if i copy encrypt function to another file and run it separately - it delete the file provided - no problem. But in this script i get [win32] None errors - it just refuse to delete any file.
Can anyone kindly point at the point i'm missing? Thanks alot !
PS It supposed to go through folder(subfolders), look for .pdf files and encrypt/decrypt them.

Found the issue, sorry :P
reader = PyPDF2.PdfFileReader(open(filename, "rb"))

Encrypting a file using saved RSA keys in python

I am trying to encrypt an image file using RSA keys that are generated by another script and saved into a .pem file. when i am trying to encrypt the file its showing errors like this
Traceback (most recent call last):
File "rsaencrypt.py", line 85, in <module>
main()
File "rsaencrypt.py", line 45, in main
content = fileObj.read()
File "/usr/lib64/python3.7/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte
I am new to python and file handling so i think the problem is in the way of how i am handling the files both the key files and the inputfile. Looking forward to some suggestion.
Heres the code of my encryption file:
import time, os, sys
def main():
inputFilename = 'img.jpg'
# BE CAREFUL! If a file with the outputFilename name already exists,
# this program will overwrite that file.
outputFilename = 'encrypted.jpg'
myKey = open("public_key.pem",'r')
myMode = 'encrypt' # set to 'encrypt' or 'decrypt'
# If the input file does not exist, then the program terminates early.
if not os.path.exists(inputFilename):
print('The file %s does not exist. Quitting...' % (inputFilename))
sys.exit()
# If the output file already exists, give the user a chance to quit.
if os.path.exists(outputFilename):
print('This will overwrite the file %s. (C)ontinue or (Q)uit?' % (outputFilename))
response = input('> ')
if not response.lower().startswith('c'):
sys.exit()
# Read in the message from the input file
fileObj = open(inputFilename)
content = fileObj.read()
fileObj.close()
print('%sing...' % (myMode.title()))
# Measure how long the encryption/decryption takes.
startTime = time.time()
if myMode == 'encrypt':
translated = transpositionEncrypt.encryptMessage(myKey, content)
elif myMode == 'decrypt':
translated = transpositionDecrypt.decryptMessage(myKey, content)
totalTime = round(time.time() - startTime, 2)
print('%sion time: %s seconds' % (myMode.title(), totalTime))
# Write out the translated message to the output file.
outputFileObj = open(outputFilename, 'w')
outputFileObj.write(translated)
outputFileObj.close()
print('Done %sing %s (%s characters).' % (myMode, inputFilename, len(content)))
print('%sed file is %s.' % (myMode.title(), outputFilename))
# If transpositionCipherFile.py is run (instead of imported as a module)
# call the main() function.
if __name__ == '__main__':
main()

You need to open the file in binary mode, not text (which is the default).
Turn
fileObj = open(inputFilename)
into
fileObj = open(inputFilename, "rb")
and .read() will return bytes (i.e. binary data), not str (i.e. text).

Encoding issues while saving json to file

I am reading logs from mobile device, from system terminal line by line and saving it to string.
Then I cut this string into parts and want to generate .*json file from it.
I have my .*json in form of dictionary and I want to save it to file with usage of this custom made method:
def save_json_to_file(json_dict, folder, file_name, extension):
directory = add_ending_slash(GlobalConfig.OUTPUT_DIR) + add_ending_slash(str(folder))
file_path = clean_path(directory + str(file_name) + "." + extension)
output_file = None
try:
if not os.path.exists(directory):
os.makedirs(directory)
output_file = open(file_path, "w")
absolute_path = os.path.abspath(file_path)
Printer.system_message(TAG, "Created json file '" + absolute_path + "'.")
json.dump(json_dict, output_file, indent=4, ensure_ascii=False)
except Exception as e:
message = "Unable to create file '{}.{}'. Error message: {}"
message = message.format(file_path, extension, str(e))
raise LauncherFlowInterruptedException(TAG, message)
finally:
if output_file is not None and hasattr(output_file, "close"):
output_file.close()
return absolute_path
At some point of json.dump doing it's job I get crash:
File "/Users/F1sherKK/anaconda3/lib/python3.6/codecs.py", line 321, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc0 in position 89: invalid start byte
I tried changing every string I receive from console by doing:
received_terminal_line = received_terminal_line.encode('utf-8')
I know that in incoming strings there can be various different encodings, in example emoji.

pyCURL download and get content from mp3 file

content = content_file.read()
return content
How I can get normal characters (in UTF8) ? thanks.

try to remove ch.setopt(curl.TRANSFERTEXT, True), cause mp3 is binary.
After that change fp = open('audio.txt', "wb") to fp = open('audio.mp3', "wb")
now you'll have correct mp3 saved on disk.
Then try use following
import mp3play
filename = r'audio.mp3'
mp3 = mp3play.load(filename)
mp3.play()
you should have installed mp3play package.

Write and Save As with python in plugin QGIS

I try to make plugin in QGIS and i want to make save as button but i got error message like this

I try to save file in different format

The error message tells you exactly what the problem is:
filename = QtGui.QFileDialog(self).getSaveFileName()
if not filename.isEmpty():
filename is a unicode object, which doesn't have an isEmpty() method. Try:
if filename != "":
or, as empty strings are False-y:
if filename:
