# calc the magnitude (abs) and the phase of a complex number from cmath import phase # No need to import abs() c = 1 + 2j print(abs(c)) # Should print 2.23606797749979 print(phase(c)) # Should print 1.1071487177940904
Here is what the above code is Doing:
1. Importing the phase() function from the cmath module.
2. Creating a complex number c.
3. Printing the magnitude of c.
4. Printing the phase of c.
@client.event async def on_message(message): await message.delete(message) Here is what the above code is Doing: 1. When the bot starts up, it will print ‘Logged in as ‘ in the console. 2. When a message is sent, it will be deleted.
>>> # Create a `Sequential` model and add a Dense layer as the first layer. >>> model = tf.keras.models.Sequential() >>> model.add(tf.keras.Input(shape=(16,))) >>> model.add(tf.keras.layers.Dense(32, activation=’relu’)) >>> # Now the model will take as input arrays of shape (None, 16) >>> # and output arrays of shape (None, 32). >>> # Note that after the first layer,…

def rolling_window(a, window): shape = a.shape[:-1] + (a.shape[-1] – window + 1, window) strides = a.strides + (a.strides[-1],) return np.lib.stride_tricks.as_strided(a, shape=shape, strides=strides) Here is what the above code is Doing: 1. The first line is just a reshape of the array. 2. The second line is a bit more complicated. It’s creating a new array…
helvetica_font = tkFont.Font(family=”Helvetica”,size=36,weight=”bold”) Here is what the above code is Doing: 1. We’re creating a new font object, and we’re calling it helvetica_font. 2. We’re telling tkinter that we want the font to be in the Helvetica family. 3. We’re telling tkinter that we want the font to be size 36. 4. We’re telling tkinter…
You can use threading to solve your problem. You can put your image writing function inside a new thread and then that task will get independent of your UI part and hence it will not lag. I have done it and let me know if you need any further help. Here is what the above…
