Which of the following scenarios would most likely require the use of a multiline string in Python?
- Storing a short password for later authentication.
- Displaying a complex, formatted help message to the user in a command-line interface. (correct)
- Storing a user's age as a string to avoid integer overflow issues.
- Performing calculations in a Python script.
Given a string variable `text = "Python is fun!"
Given a string variable `text = "Python is fun!"
- `"fun!"`
- `"Python"`
- `text[9:]` (correct)
- `text[10:len(text)]`
Consider the following Python code:
number = "123"
result = number + 456
What will happen when this code is executed?
Consider the following Python code:
number = "123"
result = number + 456
What will happen when this code is executed?
- The code will raise a `TypeError` because you cannot directly add a string and an integer. (correct)
- The code will execute successfully, and `result` will be the integer 123456.
- The code will execute successfully, and `result` will be the string "123456".
- The code will execute successfully, and `result` will be the integer 579.

Study Notes
Strings
- A string is a piece of text-based information surrounded by quotation marks.
- Strings can be assigned to variables.
- Either single or double quotes can be used to create a string.
- Strings can contain multiple words.
- Strings can also include numbers.
- Strings are also referred to as string literals.
Substrings
- A substring is a section of an existing string.
Strings Holding Numbers
- Strings can consist of numbers.
- Strings that contain numbers are not the same as the integer data type.
- Math operations cannot be performed on strings without converting them to a numerical data type first.
Multiline Strings
- Multiline strings can hold large amounts of text that span multiple lines of code.
- Multiline strings are created using three sets of quotes (either double or single) before and after the text.
