Besides numbers, Python can also manipulate strings, which
can be expressed in several ways. They can be enclosed in single quotes ('...')
or double quotes ("...") with the same
result. \ can be used to escape quotes.
In the interactive interpreter, the output string is enclosed in quotes and
special characters are escaped with backslashes. While this might sometimes
look different from the input (the enclosing quotes could change), the two
strings are equivalent.
The string is enclosed in double quotes if the string
contains a single quote and no double quotes, otherwise it is enclosed in
single quotes. The print() function produces a more readable output, by
omitting the enclosing quotes and by printing escaped and special characters.
If you don’t want characters prefaced by \
to be interpreted as special characters, you can use raw strings
by adding an r before the first quote.
