#Total Votes Calculation:
#If votes_candidate_A = 1500 and votes_candidate_B = 1300, then the total votes can be calculated as:
#pythtotal_votes results in 2800
votes_candidate_A = 1500
votes_candidate_B = 1300
total_votes = votes_candidate_A + votes_candidate_B
print(total_votes)

#Impact of Variable Modification
#Modifying a value in one variable can affect calculations involving other variables.

x = 10
y = 5
sum = x + y  # sum is 15
x = 20
sum = x + y  # sum is now 25

#Initial Data Assignment
total_voters = 10000
voters_voted = 6000
mail_in_votes = 500

turnout_percentage = (voters_voted / total_voters) * 100  # turnout_percentage is now 65.0

#Indexing Characters
#Characters in a string are identified by their index numbers, which can be positive or negative.
#Positive indexing starts at 0 from the beginning.
#Negative indexing starts at -1 from the end.

greeting = "Hello"
first_char = greeting[0]  # 'H'
last_char = greeting[-1]  # 'o'
print(first_char)
print(last_char)

#Concatenating Strings
#Combining first and last names:
first_name = "Jane"
last_name = "Smith"
full_name = first_name + " " + last_name  # "Jane Smith"
print(full_name)


#Slicing Strings
#Extracting the area code from a phone number:
phone_number = "123-456-7890"
area_code = phone_number[0:3]  # "123"
print(area_code)

# Tuples
# Storing fixed coordinates of polling stations:
# python

# Dictionaries
# Storing voter information:
# python
voter_info = {"name": "John Doe", "age": 30, "city": "New York"}

# Storing unique voter IDs:
# python

# ELIF Statement
# Checks multiple conditions.
# Example:
# python

elif age >= 18:
    print("You can pre-register to vote.")
else:
    print("You are too young to vote.")

# OR Operator
# Checks if at least one condition is true.
# Example:
# python
