Python Keywords
Keywords are the reserved words used in Python programming language. These keywords have special meaning and cannot be used as variable names or function names in a program. In Python, keywords are case-sensitive.
Here's the list of Python Keywords:
and as assert break
class continue def del
elif else except False
finally for from global
if import in is
lambda None nonlocal not
or pass raise return
True try while with
yield
Syntax
There is no syntax for Python keywords as they are already built-in.
Examples
Here are some examples of Python keywords used in code:
# defining a function
def greet(name):
print(f"Hello, {name}!")
# using if-else keyword in conditional statement
x = 5
if x > 10:
print("x is greater than 10")
else:
print("x is less than or equal to 10")
# for loop with the help of a keyword
for i in range(1, 6):
print(i)
Explanation
Python keywords are used to create blocks of code, such as if-else statements, loops, and functions. These keywords modify the flow of the code, define functions, classes, and variables, and handle exceptions. For example, the if
keyword is used to create a conditional statement, while the def
keyword is used to define a function. The in
keyword is used to check if a value is present in a sequence or not.
Use
It is important to remember that Python keywords cannot be used as variable names, function names, or any other identifier names in the program. They can, however, be used as dictionary keys, class instance variables, or module names.
Important Points
- Python keywords are case-sensitive.
- The
None
keyword represents a null value in Python. - The
try
andexcept
keywords are used for exception handling in Python. - Keywords like
True
andFalse
are used to represent boolean values.
Summary
Python keywords are built-in reserved words that have a special meaning and cannot be used as variable names or function names. They are case-sensitive. Some of the keywords are if
, else
, for
, while
, and
, or
, def
, class
, try
, except
, True
, and False
. It is important to not use these keywords as variable or function names in your program to avoid syntax errors.
