# Introduction to Basic Data Types and Variables

# Working with Lists
my_list = [1, 2, 3, 4, 5]            # Creating a list
my_list.append(6)                   # Adding an element to the end of the list

# Exploring Dictionaries

# Manipulating Sets
my_set = {1, 2, 3, 4, 5}             # Creating a set
my_set.add(6)                       # Adding an element

# Understanding Tuples

# Conditional Statements

# Loops

# For Loop - Iterates over a sequence

# While Loop - Repeats as long as a condition is true
i = 0
while i < 5:

# Basic String Operations
str1 = "Hello"

# String Formatting using f-strings

# String Indexing and Slicing
print("First character of String:", concatenated_str[0])
print("Substring of String:", concatenated_str[6:])

# Membership Check
print("Is 'Hello' in String?", 'Hello' in concatenated_str)
