* fix: corrected placement of notes Some "note" fields were preemptive in their placement; I corrected their placement to be in more appropriate locations. * update: added additional note fields Added some additional "note" fields to assist those who are reading through the PHP documentation. * fix: formatting of escape sequence examples The formatting was a bit jumbled, so I cleaned up the formatting of the escape sequence. * update: improved examples I added a new example to demonstrate the use of a "break" statement in a while loop, as well as numbered each example. * update: add clarifying statement I added a note at the end of the description, with the goal of being a bit more explicit in terms of what the "continue" statement does.

| Python Escape Sequences |
A list of escape sequences can be found here
Escape sequences allow for including special characters into strings.
>>> print('Single quote strings can have \'single\' quotes if they are escaped')
"Single quote strings can have 'single' quotes if they are escaped"
>>> print("Double quote strings can have \"double\" quotes if they are escaped")
'Double quote strings can have "double" quotes if they are escaped'
>>> print("Multiline strings\ncan be created\nusing escape sequences.")
Multiline strings
can be created
using escape sequences.
>>> print("Backslashes \\ need to be escaped.")
Backslashes \ need to be escaped.
A raw string can be used by prefixing the string with r or R which allows for backslashes to be included without the need to escape them -
>>> print(r"Backslashes \ don't need to be escaped in raw strings.")
Backslashes \ don't need to be escaped in raw strings.
>>> print(r"An odd number of backslashes at the end of a raw string will cause an error\")
File "<stdin>", line 1
print(r"An odd number of backslashes at the end of a raw string will cause an error\")

SyntaxError: EOL while scanning string literal.
Some more examples of escape sequences.
Escape Sequence <- Intended Character
- \\ <- backslash
- \' <- single quote / apostrophe
- \" <- double quote / quotation mark
- \a <- ASCII bell makes ringing the bell alert sounds ( eg. xterm )
- \b <- ASCII backspace ( BS ) removes previous character
- \n <- newline
- \r <- carriage return
