RunPython ("import Test; Test.sayhi('" & name & "')")
Here is what the above code is Doing:
1. Create a new Python interpreter.
2. Import the Test module.
3. Call the sayhi function in the Test module.
4. Destroy the Python interpreter.
plt.ticklabel_format(style=’plain’, axis=’y’) Here is what the above code is Doing: 1. We’re creating a figure object called fig, and an axis object in that figure called ax. 2. We’re plotting (with errorbars) the data we’ve read into our pandas dataframe, df, with the data in the ‘x’ column on the x-axis, and the data in…
f = np.fft.fft2(img) fshift = np.fft.fftshift(f) fshift = np.fft.ifftshift(fshift) Here is what the above code is Doing: 1. fft2: Compute the 2-dimensional discrete Fourier Transform. 2. fftshift: Shift the zero-frequency component to the center of the spectrum. 3. ifftshift: The inverse of fftshift.
df = DataFrame({‘var_1’:[‘a’,’b’,’c’], ‘var_2’:[1, 2, 3], ‘var_3’:[‘apple’, ‘banana’, ‘pear’]}) cols = [‘var_1’, ‘var_2’] # Set columns to combine df[‘combined’] = df[cols].apply(lambda row: ‘, ‘.join(row.values.astype(str)), axis=1) # Define which column is index df_i = df.set_index(‘combined’) # Set the index to None df_i.index.names = [None] Here is what the above code is Doing: 1. Create a DataFrame…
my_callbacks = [ tf.keras.callbacks.EarlyStopping(patience=2), tf.keras.callbacks.ModelCheckpoint(filepath=’model.{epoch:02d}-{val_loss:.2f}.h5′), tf.keras.callbacks.TensorBoard(log_dir=’./logs’), ] model.fit(dataset, epochs=10, callbacks=my_callbacks) Here is what the above code is Doing: 1. The first callback we’re passing is EarlyStopping. This callback will stop training when it sees that the validation loss isn’t decreasing for two epochs. 2. The second callback we’re passing is ModelCheckpoint. This callback saves the…
[1, 2, 3, 4, 1, 4, 1].count(1) # result 3 Here is what the above code is Doing: 1. We’re creating a list of integers. 2. We’re using the count() method to count the number of times 1 appears in the list. 3. We’re printing the result.
text = ‘Some text’ htmlWidget = widgets.HTML(value = f”{text}”) labelWidget = widgets.Label(value = r’\(\color{red} {‘ + text + ‘}\)’) Here is what the above code is Doing: 1. We create a string variable called text and assign it the value ‘Some text’ 2. We create an HTML widget and assign it the value of the…
