Reserved Keywords

Reserved Keywords

In Python, there are certain reserved keywords that have predefined meanings and cannot be used as identifiers (such as variable names or function names) in your code. Here is a list of Python reserved keywords:

• False
• await
• else
• import
• pass
• None
• break
• except
• in
• raise
• True
• class
• finally
• is
• return
• and
• continue
• for
• lambda
• try
• as
• def
• from
• nonlocal
• while
• assert
• del
• global
• not
• with
• async
• elif
• if
• or
• yield

False	await	else	import	pass
None	break	except	in	raise
True	class	finally	is	return
and	continue	for	lambda	try
as	def	from	nonlocal	while
assert	del	global	not	with
async	elif	if	or	yield

These keywords are used to define the syntax and structure of the Python language and cannot be redefined or reassigned. Attempting to use any of these keywords as identifiers will result in a syntax error.

Escape Sequences

Escape sequences in Python are special characters that are used to represent non-printable characters or to produce special formatting within strings. They are represented by a backslash ('\') followed by one or more characters. Some common escape sequences in Python include:

Character Constant	Meaning
\n	Move to new line
\t	Horizontal tab
\\	Backslash
\'	Single quote
\"	Double quote
\b	Backspace
\r	Carriage return
\f	Formfeed
\nnn	Octal value
\xhh	Hexadecimal Representation

Demonstrating the usage:

print("This is a newline.\nThis is on a new line.")
print("This is a tab.\tTabbed text here.")
print("This is a backslash: \\")
print("This is a single quote: '")
print('This is a double quote: "')
print("This is a backspace: abc\bdef")
print("This is a carriage return:\rReturn to the beginning.")
print("This is a formfeed:\fNew page.")
print("This is an octal value: \101")
print("This is a hexadecimal value: \x41")

This is a newline.    
This is on a new line.
This is a tab.  Tabbed text here.
This is a backslash: \
This is a single quote: '        
This is a double quote: "        
This is a backspace: abdef       
Return to the beginning.n:       
This is a formfeed:♀New page.    
This is an octal value: A        
This is a hexadecimal value: A

These escape sequences allow you to include special characters or control the formatting of strings within your Python code.
