Select any of the following that are string literal values.

Select every one that is a string literal, then check.

• "5"
  Correct. This is valid, complete, quoted text, so it is a string literal no matter what is written inside the quotes.
• my_string
  Not quite. There are no quotes here, so Python reads this as a bare identifier, a variable name, not a literal value.
• "my_variable"
  Correct. It is fully quoted with matching double quotes, so it is a string literal even though the text inside looks like a variable name.
• _5
  Not quite. Without quotes, this is a bare identifier, not a string literal.
• 5
  Not quite. Without quotes, this is an integer literal, not a string.
• "Hello
  Not quite. The opening quote is never closed with a matching quote, so this is not a valid literal at all.
• 'World"
  Not quite. The opening single quote is closed with a double quote instead of a matching single quote, so this is not a valid literal.

True or False: Strings are composed of only letters and symbols.

Select one answer, then check.

• False
  Correct. Strings are made of letters, numbers, and symbols, so digits like the 5 in "5" can appear inside a string too.
• True
  Not quite. Strings can also contain digits, so limiting them to only letters and symbols leaves out numbers.

"1" + "1" = "2"

Select one answer, then check.

• False
  Correct. The + operator concatenates strings instead of adding them numerically, so "1" + "1" evaluates to "11", not "2".
• True
  Not quite. Python's + operator on two strings joins their text rather than doing arithmetic, so the result is "11", not "2".
