Do you want to become a Python developer but don’t know where to start? If that’s the case, you’re in the right place. In this Python 2021 roadmap, I will show you everything you need to know in order to become a python developer. Let’s jump right into it!

Step 1: Introduction

First introduces yourself to the fundamentals of Python, what makes it so massively popular, and its benefits and limitations. It also compares Python with other languages like Java, Scala, and R.

• Introduction to Python

• Python vs Scala
• Python vs R
• Applications of Python
• Compilers and Interpreters Available
• Getting to Know the Python Interpreter
• Flavours of Python

Step 2: Basics

We then learn basics of Python- variables, data types, and operators. also learn concepts like looping and decision making.

• Python Variables
  • Python Variable Scope
• Data Types in Python
• Python Operators
  • Bitwise Operators
  • Comparison Operators
  • Operator Precedence
  • Ternary Operators
• Python Decision Making

• Python Tuples
  • The zip() Function
  • Tuples vs Lists
• Slicing in Python
• Binary Sequence Types- bytes, bytearray, memoryview
• Dictionaries in Python
• Sets in Python
• Booleans in Python

Step 4: Functional Programming

Next, Learn about functional programming with concepts like function arguments and lambda expressions. also take a good look at some important built-in functions. Finally, atlast learn decorators, closure, and itertools.

• Functions in Python
• Lambda Expressions
• Function Arguments
• Function Recursion
• Built-in Functions
  • range()
  • eval()

• Working with itertools

Step 5: Modules and Packages

Next is to learn how to create modules and packages, and practice some important ones. then compare packages and modules.

• Modules
  • Counter
  • Defaultdict
  • OrderedDict
  • namedtuple
  • Numeric Modules- math, decimal, random
  • sys
  • Generating Random Numbers
• Packages
  • pip and PyPI
  • Modules vs Packages

Step 6: Miscellany

Time to dig deeper into Python! This Step takes you to more advanced concepts like regular expressions, date and time, and debugging.

• Regular Expressions with Python
• Multithreading in Python
• Working with Date and Time
• Namespace and Scope
• Virtual Environments and Packages
• The datetime Module – Part I
• The datetime Module – Part II
• The calendar Module
• The Python Debugger (pdb)
• CGI Programming with Python
• Understanding urllib
• Terminologies in Python
• What’s new in Python 3.7?
• Deep Copy vs Shallow Copy
• Assert Statements in Python
• Pretty-Printing with pprint

Steps 7: Object-Oriented Programming

We now begin talking object-oriented programming. We talk of classes, methods, and objects. Then, we try a hand at inheritance and operator overloading. Finally, we discuss concepts like generators, iterators, and property.

• Methods in Python
  • Methods vs Functions
  • Magic (Dunder) Methods
• Classes in Python
  • Abstract class
  • Concrete class
• Python Objects
• Inheritance in Python
• Multiple Inheritance
• Python Operator Overloading
• Generators in Python
• Iterators in Python
  • Generators vs Iterators
• Serialization with pickle
• The property Decorator

Step 8: File Handling

now explore other concepts like file handling. This module teaches you to manipulate files with the help of the OS and shutil modules. you will also learn how to copy, rename, and zip files using Python.

• Reading and Writing Files
• Managing Directories and Files
• The OS Module
• The shutil Module
• Copying Files with Python
• Renaming Files with Python
• Zipping Files with Python

Step 9: Exception Handling

now learn about Exception handling and unittest

• Errors and Exceptions
• Exception Handling
• Testing with unittest

Step 10: Important Libraries

With such powerful libraries by your side, it is possible to nurture the true power of a tool like Python.

• Python Libraries
• NumPy
• SciPy
• pandas
• Visualizing with matplotlib
• PyQT
• PyGTK
• PyTorch
• Altair
• Web Scraping with Scrapy
• Data access mechanisms
