# Homework Lesson 2 - Strings

# READ CAREFULLY THE EXERCISE DESCRIPTION AND SOLVE IT RIGHT AFTER IT

# ---------------------------------------------------------------------
# Exercise 1: Personalized Greeting
# Write a program that takes a user's name as input
# and then greets them using an f-string: "Hello, [name]!"
#
# Example Input: "Alice"
# Example Output: "Hello, Alice!"
name = input("Enter yor name: ")
print(f"hello {name}")

# ---------------------------------------------------------------------
# Exercise 2: Greeting with User's Favorite Activity
# Write a program that takes a user's name and their
# favorite activity as input, and then greets them
# using the formatting method of your choice as:
# "Hello, [name]! Enjoy [activity]!"

# Example Input:
# Name: Emily
# Favorite Activity: hiking
# Example Output: "Hello, Emily! Enjoy hiking!"

name = input("Enter your name: ")
activity = input("Enter your favorite activity: ")
print(f'hello {name}! Enjoy your {activity}')


# ---------------------------------------------------------------------
# Exercise 3: Membership Cards
# You are designing a simple registration system for a club.
# When new members sign up, you want to ensure their names
# are displayed in uppercase on their membership cards.
# Write a program that takes the new member's name as
# input and prints it in uppercase and prints a welcome message
# using .format()

# Example Input:
# Name: Emily
# Example Output: "Welcome, Emily! Your name in uppercase is: EMILY!"

name = input("Enter your name: ")
print(f'Welcome to the program {name.upper()}, we are excited to have you!')


# ---------------------------------------------------------------------
# Exercise 4: User Profile Creation
# Build a user profile generator. Ask
# the user for their first name, last name, and age. Create
# a profile summary using .title(), .upper(), and .format().
#
# Example Input:
# First name: john
# Last name: smith
# Age: 28
#
# Example Output:
# Name: John Smith
# Age: 28

name = input("Enter your name: ")
last_name = input("Enter your last name: ")
age = input("Enter your age: ")
print(f"{name.upper()} , {last_name.title()} , {age} years old"  .format(name='Erik', last_name='Abrahamyan', age='17'))




# ---------------------------------------------------------------------
# Exercise 5: Text message limits
# You are developing a text messaging application that limits the
# number of characters in a single message. Your task is to create
# a Python program that takes a message as input from the user.
# The program should calculate and display the number of characters
# in the message, including spaces, and format the output using
# an f-string. This character count will help users ensure their
# messages fit within the allowed limit.

text = input("Enter your text: ")
print(len(text))


# ---------------------------------------------------------------------
# Exercise 6: Text Transformation Game
# Create a text transformation game. Ask the user
# to enter a sentence. Replace all vowels with '*'. Display the
# modified sentence.
#
# Example Input: "Hello, world!"
# Example Output: "H*ll*, w*rld!"

sentence = input("Enter a sentence: ")
print(sentence.replace('a' , '*'))



# ------------------------------# ---------------------------------------------------------------------
# Exercise 7: Extracting Information
# The variable 'data' is a student record in the format "name:age"
# Use string slicing and string methods to extract the name and the age
# and print the result formatted.
#
# data = "lucy smith:28"
#
# Expected output:
# Name: Lucy Smith
# Age: 28

string = 'lucy smith:28'
substring = string[0:10]
substring_age = string[11:13]
print(substring)
print(substring_age)



# ---------------------------------------------------------------------
# Exercise 8: Miles to Kilometers Conversion
# Write a program that converts a distance in miles to kilometers.
# Take the distance in miles as input, convert it to kilometers
# using the formula miles * 1.6, and display the
# result using f-strings.

# Example Input: 10
# Example Output: 10 miles is approximately 16.0 kilometers.

# We are converting the input string to float:
# Input: float("1.23")
# Output: 1.23
miles = float(input("Enter distance in miles: "))
kilometers = miles * 1.6
print(kilometers)


# ---------------------------------------------------------------------
# Exercise 9: Workouts calculator
# Write a Python program that asks the user to input the number
# of minutes spent on three different exercises: cardio, strength
# training, and yoga using the input() function. Convert the input
# strings to integers using the int() function. Calculate the
# total time spent on workouts by summing up the minutes from all
# three activities. Based on the total workout time, provide a
# motivational message using an f-string that encourages the user
# to stay consistent and reach their fitness goals. Display the
# motivational message to the user.

text_one = int(input("Minutes spent on cardio: "))
text_two = int(input("Minutes spent on yoga: "))
text_three = int(input("Minutes spent on strength training: "))
motivation = "Great Job on Your Workout! Keep Going!"
result = text_one + text_two + text_three, f'minutes'
print(result)
print(motivation)



# # ---------------------------------------------------------------------
# # Challenge 1 (OPTIONAL!): Reverse the negative integer -324 and keep
# # the negative symbol. Expected output: -423
# input_number = -324
#
# # Convert the integer to a string to handle the negative symbol separately
# num_str = str(input_number)
#
# # Reverse the digits (excluding the negative symbol) using slicing [::-1]
# # Use this simple guide to help you slice the reversed string:
# # http://bit.ly/3siP47n
#
# # (ADD YOUR CODE BELOW)
#
# # Add the negative symbol back to the reversed string
# reversed_num = int(num_str[0] + reversed_str)
#
# # Output the result
# # (ADD YOUR CODE BELOW)
#
# # ---------------------------------------------------------------------
# # Challenge 2 (OPTIONAL!): Formatting Average Speed
# # In this exercise, we're developing a program to determine the
# # average speed of a truck based on the distance traveled in miles
# # and the total time taken in hours. Your task is to format and display
# # this average speed accurately.
# # Task:
# # Your program should take the number of miles and the total number
# # of hours traveled as input and calculate the average speed. Then,
# # present the average speed in a user-friendly format, rounded to one
# # decimal place.
# #
# # Example:
# # If the driver covered 60 miles in 3 hours, the calculated average
# # speed is 20.0 miles per hour. However, we want to display it as
# # 'The average speed is 20.0 miles per hour'.
# #
# # Similarly, for 55 miles and 3 hours, the calculated speed is
# #  approximately 18.33333333332, but we want to format and display
# #  it as 'The average speed is 18.3 miles per hour'.
# #
# # Hints:
# # Refer to the "Format examples" section in the official Python
# # documentation for string formatting techniques:
# # https://docs.python.org/3/library/string.html#format-examples
# # Experiment with different formatting options to achieve the
# # desired presentation of the average speed.
#
# # Taking input for miles and hours
# miles = int(input("Enter the number of miles: "))
# hours = int(input("Enter the total number of hours: "))
#
# # Calculating average speed
# average_speed = miles / hours
#
# # Formatting and displaying the result
# # (Your code here)
#
#
# print(f"The average speed is {rounded_speed} miles per hour")
