How To Define a Function in Python
Published on Aug. 22, 2023, 12:15 p.m.
To define a function in Python, you use the def
keyword, followed by the function name, a pair of parentheses, and a colon. Any parameters that the function takes should be listed inside the parentheses. Here’s an example:
def greet(name):
print("Hello, " + name + "!")
In this example, we define a function called greet
that takes one parameter name
. When the function is called, it will print a greeting message to the console with the name that was passed in as an argument.
You can also include a return
statement in your function to return a value to the caller. Here’s an example:
def add(a, b):
return a + b
In this example, we define a function called add
that takes two parameters a
and b
. The function returns the sum of these two values.
