The following are all literals in Python:
42                       # Integer literal
3.14                     # Floating-point literal
1.0j                     # Imaginary literal
'hello'                  # String literal
"world"                  # Another string literal
"""Good night"""                 # Triple-quoted string literal

Using literals and delimiters, you can create data values of some other fundamental types:
[ 42, 3.14, 'hello' ]    # List
( 100, 200, 300 )        # Tuple
{ 'x':42, 'y':3.14 }     # Dictionary
