sum(l) / len(l)
Here is what the above code is Doing:
1. We’re creating a function called average that takes a list of numbers as an argument.
2. We’re creating a variable called length and setting it to the length of the list.
3. We’re creating a variable called sum and setting it to 0.
4. We’re creating a for loop that goes through each number in the list and adds it to sum.
5. We’re dividing sum by length to get the mean.
6. We’re returning the mean.
model_reg.fit(scaled_x_train.values, y_train[vp].values) data_pred = model_reg.predict(scaled_x_test.values) Here is what the above code is Doing: 1. We are creating a linear regression model. 2. We are fitting the model with the training data. 3. We are predicting the values of the test data.
if variable: # code goes here… Here is what the above code is Doing: 1. It’s checking if the variable is True. 2. If it is, it runs the code inside the if statement. 3. If it’s not, it skips the code inside the if statement. You can also use the ‘else’ keyword to run…
from selenium.webdriver.common.action_chains import ActionChains button = driver.find_element_by_class_name(u”infoDismiss”) driver.implicitly_wait(10) ActionChains(driver).move_to_element(button).click(button).perform() Here is what the above code is Doing: 1. Find the element with class name “infoDismiss” 2. Wait for the element to be visible 3. Move the mouse to the element 4. Click on the element
from collections import defaultdict d_int = defaultdict(int) d_list = defaultdict(list) def foo(): return ‘default value’ d_foo = defaultdict(foo) >>> d_int defaultdict(, {}) >>> d_list defaultdict(, {}) >>> d_foo defaultdict(, {}) Here is what the above code is Doing: 1. We create a defaultdict with int as the default_factory. 2. We create a defaultdict with list…
