#Python #List

A list is a common Python datatype that is ordered and changeable. It allows duplicate values.

Creating a list is as simple as putting different comma-separated values between square brackets:

animals = ["Cow", "Ox", "Got"]

A python list is very important especially for data science and Machine learning because the data of datasets are organized in a list form. We can further investigate the future predictions based on the list of data.

#TIP #help_function

Python has many more functions, and defining your own functions is a big part of python programming.

The help() function is possibly the most important Python function you can learn. If you can remember how to use help(), you hold the key to understanding most other function.

Here is an example:

help(round)

#Question_by_user
Q: "Can somebody help me in putting list in CSV file in Python"

#Solution

# first create a list with items you would like to save a csv file
big_list = [{'name': 'Fredrick Stein', 'userid': 6712359021, 'is_admin': False},
{'name': 'Wiltmore Denis', 'userid': 2525942, 'is_admin': False},
{'name': 'Greely Plonk', 'userid': 15890235, 'is_admin': False},
{'name': 'Dendris Stulo', 'userid': 572189563, 'is_admin': True}]
# import csv module
import csv

# create afile with open function with a temporary file name output.csv
with open('output.csv', 'w') as output_csv:
# create a list of headers
fields = ['name', 'userid', 'is_admin']
# write the output using dictionary writter function
output_writer = csv.DictWriter(output_csv, fieldnames=fields)
# write the headers
output_writer.writeheader()
# create for loop which iterate each list and write a row
for item in big_list:
output_writer.writerow(item)

One more #question_by_another_user
#Q: "What is the d/nce b/n Machine learning and Data science ...?"

#CODE_CHALLENGE #PYTHON_LIST #LOOPS #FUNCTIONS

1. Write a function called delete_starting_evens() that has a parameter named lst.

The function should remove elements from the front of lst until the front of the list is not even. The function should then return lst.

For example if lst started as [4, 8, 10, 11, 12, 15], then delete_starting_evens(lst) should return [11, 12, 15].

Make sure your function works even if every element in the list is even!

NEURAL NETWORK
A neural network is a network or circuit of neurons,or in a modern sense, an artificial neural network, composed of artificial neurons or nodes. This a neural network is either a biological neutral network, mafe up of real biological neurons or an artificial neural network for solving Artificial Intelligence problems. The connections of the biological neurons are modelled as weight. A positive weight reflects and extraordinary collection, while negative values means inhibitory connections. All inputs are modified by weight and summed. This activity is referred to as a linear combination. Finally and activation function control ls the Amplitude of the output. For example and acceptable range of output is usually between 0 and 1, or it could be -1 and 1.

Why we choice Python ? Well, Python is the library with the most complete set of Neural Network library . I will use Keras.
Keras is a higher-level abstraction for the popular neural network library, Tensorflow. Because of the high level of abstraction, you don’t have to build a low-level Linear Algorithm and Multivariate Calculus by yourself.
