strings.py

# • A string literal is enclosed in either single quotes, double quotes, or either quotation mark
# repeated three times. When the quotation mark is repeated three times, the string may span
# multiple lines.
# • Strings are immutable.
# • Strings can be concatenated using the plus operator.
# • A string can be repeated by multiplying it by an integer.
# • The str() function converts its argument to a string.
# • A string is a sequence. Thus:
# – A string can be used as the iterable in the header of a for-loop (in which case the loop
# variable takes on the values of the individual characters of the string).
# – The len() function returns the length of a string, i.e., the number of characters.
# – An individual character in a string can be accessed by specifying the character’s index
# within brackets.
# – Slicing can be used to obtain a portion (or all) of a string.
