• Python’s libraries, built for data science and scientific computing, simplify complex tasks and allow more focus on problem-solving.

Core Python Libraries for Data Science

• Numpy: Key for high-speed numerical operations, especially with large datasets and complex calculations.
• Pandas: Provides structures like DataFrames, making it easy to manipulate and analyze structured data.
• Scipy: Adds advanced functions for scientific and statistical computing, often used in data modeling and optimization.
• TensorFlow: Supports building, training, and deploying machine learning models, with strong support for deep learning.

Course Overview: What You Will Learn

upGrad’s Python course provides a complete introduction to programming basics, with a focus on practical applications. 

You’ll start with setup and move through Python’s core syntax, data types, control structures, and libraries essential for data science and software development. 

By the end, you’ll have the skills to write Python code for data processing, automation, and basic analysis, equipping you for further projects in data science or programming.

Python Installation and Setup

Setting up Python is straightforward and gets you ready to start coding:

• Download Python: Go to python.org and download the latest version for your OS.
• Add Python to PATH: During installation, check “Add Python to PATH” to easily access Python from any directory.
• Choose an IDE:
  • VS Code: Lightweight, flexible, with strong plugin support.
  • PyCharm: A robust IDE with features like code completion and debugging tools.

Install Key Packages: Use pip to install foundational libraries:

pip install numpy pandas scipy matplotlib

Setting up these tools and libraries prepares you to start coding and experimenting in Python right away.

Basic Python Syntax and Data Types

A strong grasp of Python’s syntax and data types forms the base for all programming. Here’s what you’ll cover:

• Variables and Naming:
  • Python uses dynamic typing, so there’s no need to declare types explicitly.
  • Naming conventions follow snake_case, making code easy to read.
• Data Types:
  • Integers and Floats: For whole numbers and decimal values, supporting basic arithmetic operations.
  • Strings: For text data, with functions for slicing, indexing, and formatting.
  • Booleans: True/False values, used in logical and comparison operations.
• Core Data Structures:
  • Lists: Mutable collections for storing ordered items.
  • Tuples: Immutable sequences, often for fixed collections.
  • Dictionaries: Store key-value pairs, allowing efficient lookups and data retrieval.
• Conditionals:
  • If-Else Logic: Allows branching based on conditions, using comparison operators (==, !=, >, etc.) and logical operators (and, or, not).

Example:

if temperature > 30:
    print("Hot")
elif temperature > 20:
    print("Warm")
else:
    print("Cool")

• Loops:
  • For Loops: For iterating over sequences like lists, dictionaries, or ranges.
  • While Loops: Runs as long as a condition is True, suitable for repeated actions based on dynamic conditions.

Example:-

# Initialize the counter
count = 1
# While loop while count <= 5:
print(count) # Print the current count 
count += 1 # Increment the counter

These foundational concepts set the stage for building and understanding more complex programs.

Control Flow and Loops

Understanding control flow and loops allows you to create logical programs that respond to conditions and repeat tasks:

• Control Flow:
  • If Statements: Decide which code to run based on conditions.
  • Else and Elif: Provide alternative paths, enabling layered decision-making.
  • Nested Conditions: Allows for detailed checks and multi-step decisions.
• Loops:
  • For Loops: Used to iterate through elements in sequences like lists or strings.
  • While Loops: Continues running as long as a specified condition is met.

Example:

for i in range(5):
    print(i * 2)  # Prints even numbers from 0 to 8

• Loop Controls:
  • Break: Exits a loop early.
  • Continue: Skips the rest of the code in the loop for the current iteration.
  • Else in Loops: Runs if the loop completes all iterations without a break.
