String Concatenation and Repetition

📖 Scenario: You are creating a simple text generator for greeting cards. You want to build a message by joining words and repeating some parts to make it more cheerful.

🎯 Goal: Build a program that creates a greeting message by concatenating strings and repeating parts of the message.

📋 What You'll Learn

Create a string variable with a greeting word

Create a string variable with a name

Create a variable for the number of exclamation marks

💡 Why This Matters

🌍 Real World

Creating dynamic text messages is useful in apps that send notifications, emails, or personalized greetings.

💼 Career

Understanding string operations is fundamental for software development, especially in user interface design and data formatting.

1

Create greeting and name variables

Create a string variable called greeting with the value "Hello" and another string variable called name with the value "Alice".

Python

# Create the greeting and name variables
# Your code here

Need a hint?

Use the equals sign = to assign the text values to the variables.

2

Create exclamation count variable

Create an integer variable called exclamation_count and set it to 3.

Python

greeting = "Hello"
name = "Alice"
# Create the exclamation_count variable
# Your code here

Need a hint?

Remember to assign the number 3 to the variable exclamation_count.

3

Concatenate greeting and name with space

Create a string variable called message that concatenates greeting, a space " ", and name.

Python

greeting = "Hello"
name = "Alice"
exclamation_count = 3
# Concatenate greeting, space, and name into message
# Your code here

Need a hint?

Use the plus sign + to join strings. Remember to add a space between the words.

4

Add repeated exclamation marks and print

Add exclamation marks to message by concatenating message with "!" repeated exclamation_count times. Then print the final message.

Python

greeting = "Hello"
name = "Alice"
exclamation_count = 3
message = greeting + " " + name
# Add repeated exclamation marks and print message
# Your code here

Need a hint?

Use the * operator to repeat the exclamation mark string. Then use print() to show the message.
