Python is one of the top most sorted out programming language with a vast usage from web development to data science and Machine Learning. Being a scripting language, python is not only easy to learn but also easy to write as it has English-like syntax.
Python has various data types which includes numerical values, string, data structure which includes list, tuple, set and dictionary.
Declaring a variable in python is as easy as below:
name = Wambua
You can define several variables in a raw as below:
a, b, c = 1, 2,3
To display an output in python, you use the function print
For example
name = 'Otieno'
age = 12
print(name)
Integers and floats are numerical data type in python. If you want know the type of data you are dealing with you use the function type(). For example:
age = 33
type(age) #int
String is another data type in python. Unlike other languages, python does not have a character. It therefore treats a character as a string of length 1.
To know the length of a string, python uses the function len()
name = 'Daniel'
result = len(name)
print(result) #6
Functions are blocks of code that do a specific job. In python, functions are defined as below:
def add_2(x):
return x+2
To call a function, you just have write the name of the function followed by parenthesis then passing the argument if any.
add_2(5)
Data structures in python are containers for storing data for processing. These includes
-List
-Dictionary
-Tuples
-Set
We shall discuss in details the functionalities of the above data structures. Keep learning!!
