Complete roadmap to learn Python for data analysis
Step 1: Fundamentals of Python
1.
Basics of Python Programming
- Introduction to Python
- Data types (integers, floats, strings, booleans)
- Variables and constants
- Basic operators (arithmetic, comparison, logical)
2.
Control Structures
- Conditional statements (if, elif, else)
- Loops (for, while)
- List comprehensions
3.
Functions and Modules
- Defining functions
- Function arguments and return values
- Importing modules
- Built-in functions vs. user-defined functions
4.
Data Structures
- Lists, tuples, sets, dictionaries
- Manipulating data structures (add, remove, update elements)
Step 2: Advanced Python
1.
File Handling
- Reading from and writing to files
- Working with different file formats (txt, csv, json)
2.
Error Handling
- Try, except blocks
- Handling exceptions and errors gracefully
3.
