Introduction to Python language

 

There are so many programming languages. Why do we need to learn Python? What are the advantages that make Python unique for beginners to learn coding? Well, there might be many answers to this question. The best answer would be that Python is popular, especially in data science and machine learning. Python is now becoming the basic and almost unique tool to data scientist and model developers. 

Another advantage of the Python is the availability in open source libraries. Python has now been used prevalently in machine learning and deep learning with a list of high level packages available in open source, such as scikit-learn, TensorFlow, PyTorch, etc.

Python as a programming language was designed with simple syntax, emphasizing on the readability and prototyping. 

Writing the first line of code with Python on terminal or Jupyter notebook

print('All About Python')

Define a sequence of numbers

alist = [2, 3, 5, 9, 10]
print(alist)

Write a function to filter the even numbers in a list

def get_even_numbers(a):
    even_nums = []
    for x in a:
        if x % 2 == 0:  
            even_nums.append(x)
    return even_nums

get_even_numbers(alist)
