In Python, keywords are reserved words that have a specific meaning and purpose. These words cannot be used as identifiers for variables, functions, or any other user-defined items. In this blog post, we’ll explore Python keywords, providing a brief overview of each one.
Table of Python Keywords
Here’s a table listing Python’s keywords along with a short description for each:
Keyword | Description |
---|---|
and | Logical AND operator |
as | Creates an alias while importing a module |
assert | Used for debugging purposes |
async | Used to define asynchronous functions |
await | Used to call an asynchronous function and wait for result |
break | Breaks out of the current loop |
class | Used to define a class |
continue | Continues to the next iteration of the loop |
def | Used to define a function |
del | Deletes an object |
elif | Else if part of an if-else structure |
else | Else part of an if-else structure |
except | Used with exceptions, what to do when an exception occurs |
False | Boolean value, represents false |
finally | Used with exceptions, a block of code that will be run no matter if there’s an exception or not |
for | Used to create a for loop |
from | Used to import specific parts of a module |
global | Used to declare a global variable |
if | Used to make a conditional statement |
import | Used to import a module |
in | Used to check if a value is present in a sequence |
is | Used to test if two variables are the same object |
lambda | Used to create an anonymous function |
None | Represents a null value |

not | Logical NOT operator |

pass | A null statement, a place where no action occurs |
raise | Used to raise an exception |
return | Used to return a value from a function |
True | Boolean value, represents true |
try | Used to catch exceptions |
while | Used to create a while loop |
with | Used to simplify exception handling |
yield | Used to end a function and returns a generator |
Conclusion
Python’s keywords are the building blocks of the language, each serving a unique purpose in various aspects of programming. Understanding these keywords and their functions is essential for anyone learning or working with Python.
