Python Tutorial

This Python tutorial helps you to learn Python in the best possible way. We provide multiple examples on each topic. So, you can easily understand these Python tutorial topics.

Python Programming language is an object-oriented language, which is sturdy and the fastest growing language in the current situation. Python is very popular, probably because it’s easy to learn code, cross-platform support, and libraries that support Data Scientists to analyze and visualize data.

What I like about Python Programming language is its syntax structure, which removed those traditional flower brackets, semicolons, punctuations. These changes make our code simple and easy to read/understand. Being a C# developer, Python impressed me with its simple syntax, where I have to write a lot of lines to get the same result in C#. Because of this Python’s simple syntax rules, less coding drives the users to learn. I can say, by far, Python is the best language for the people who are new to programming and experienced with other programming languages.

In this Python tutorial, we used the default Python IDE for all the examples to explain each topic. However, you can choose your favorite Free/Paid code editors.

Python Operators

The Python programming language supports the following operators. We can use these operators to perform calculations on operands or values.

  1. Install IDE
  2. Arithmetic Operators
  3. Bitwise Operators
  4. Comparison Operators
  5. Logical Operators
  6. Assignment Operators

Python Flow Control Statements

Generally, flow control statements contain a condition followed by a block of code. The condition always returns either True or false. Based on the result, the flow control statement will execute the block of code. For instance, if True, the true statements will execute. Otherwise, False statements execute or exit from a control flow statement.

  1. If Statement
  2. If Else Statement
  3. Nested If Statement
  4. Elif Statement
  5. While Loop
  6. For Loop
  7. Break Statement
  8. Continue Statement

Python Built-in Functions

The Python interpreter has many built-in functions. The following are the list of all the available functions in Python programming language. To make more sense, we divided them into various sections based on their functionalities. 

Python Common Functions

The below shown Python functions are the standard functions for all the objects. I mean, you can use these functions on Lists, Strings, Tuples, Set, and Dictionary objects.

  1. len
  2. max
  3. map
  4. print
  5. sort and sorted
  6. range
  7. zip

Python Dates

  1. strftime
  2. strptime
  3. timedelta

Python Tutorial on Math Functions

Below table will show you the list of Mathematical function available in Python

Python Tutorial on String Functions

Unlike List, Python string is immutable. So, we cannot perform adding, removing kind of operations on this. However, one can perform a slice or concatenate. Apart from this, a string has its methods to convert it to uppercase and lowercase, splitting, joining, etc. The following Python tutorial sections show the list of string methods available in Python.

Python List Functions

The List Data type has separate methods for adding, removing, finding, manipulating, and reversing list items. The following are the available list functions in Python.

Python Dictionary Functions

Apart from the common functions, Python dictionary has separate functions to select, delete, update, and set values and keys. The following are the available Python dictionary functions.

  1. copy
  2. clear
  3. fromkeys
  4. get
  5. items
  6. keys
  7. len
  8. pop
  9. popitem
  10. setdefault
  11. update
  12. values

Python set Functions

  1. add
  2. clear
  3. copy
  4. discard
  5. len
  6. pop
  7. set max
  8. set min
  9. remove
  10. sorted
  11. union

Python Data Science Tutorial

Similar to any other programming language, Python is an excellent language with all the bells and whistles. However, with the introduction of the Numpy module and few other popular libraries like Pandas, SciPy, and matplotlib, it becomes a heart to Data Science precisely Data scientists. All these libraries made this regular language to the most powerful language in the current scientific world.
