Asynchronously upload images to Cloudinary using the Python API

Clash Royale CLAN TAG #URR8PPP Asynchronously upload images to Cloudinary using the Python API I am trying to asynchronously upload images to Cloudinary using their Python API. Their documentation states the following is required to upload an image. result = cloudinary.uploader.upload(file, **options) Since, I would like to upload asynchronously, it appears I need to set the "async" option to True (also in the documentation). async (Boolean): Tells Cloudinary whether to perform the upload request in the background (asynchronously). Default: false. Since options has **, as explained in this SO post, I assume that the function accepts keyword arguments like so. response = await cloudinary.uploader.upload(img, async=True) However, when I run my script, I get the following error: File "async_upload.py", line 16 response = await cloudinary.uploader.upload(img, async=True) ^ SyntaxError: invalid syntax How d...

How can I pass in parameters without calling a function in Python? [duplicate]

Clash Royale CLAN TAG #URR8PPP How can I pass in parameters without calling a function in Python? [duplicate] This question already has an answer here: I am using the Tkinter bind function, and I would like to bind a button to a function. However, this function takes parameters (which, for obvious reasons, I have put in parentheses). encrypt_button = Button(window, text='Encrypt') encrypt_button.bind('<Button-1>', bl_encrypt(foo)) My problem is that, since I am passing 'foo' into my function, the function is called whenever the program gets to this line, not when I click on the button. This would not usually happen as, if there were no parameters to be passed, I would not put parentheses after the function name. How do I bind to this function and pass parameters, but without the function being called as soon as I run the program? My Python version is 3.6.0, if that helps. This question has been asked before and already has an answer. If those answe...

What does “[*]” (star modifier) mean in C? [duplicate]

Clash Royale CLAN TAG #URR8PPP What does “[*]” (star modifier) mean in C? [duplicate] This question already has an answer here: While trying to implement a C11 parser (for educational purposes), I found that in C11 (p. 470) but also in C99 (p. 412) (thanks Johannes!), the direct declarator is defined as: (6.7.6) direct-declarator: direct-declarator [ type-qualifier-list? * ] At first, I thought this was an error in the grammar (the type list shouldn't be optional). However, when I tried this out in my reference compiler (clang), I got an rather unexpected error: int array[*] = { 1, 2, 3 }; // error: star modifier used outside of function prototype So apparently, (in clang) this is called the star modifier . I quickly learned that they can only be used in function signatures: void foobar(int array[*]) However, they can only be used in the declaration. Trying to use it in a function definition results in an error as well: void foobar(int array[*]) { // variable length array...
