Which keyword is used to create a function in Python?

In Python, the keyword that is used to create a function is "def." This keyword signals the start of a function definition. When you use "def," you provide the function name followed by parentheses, which might include parameters, and then a colon. After that, the function's code block begins on the next line, typically with an indentation.

For example, defining a simple function in Python would look like this:

def my_function():

print("Hello, World!")

This structure is critical in Python, as it clearly indicates that a new function is being defined and helps maintain the clarity and readability of the code. Other languages may have their own specific keywords for defining functions, but in Python, "def" is the standard and accepted way to do so.
