We have actually already been working with a number of Python’s built-in functions. These include print(), dict(), input(), int(), and len().
We call built-in functions using the function name, followed by parenthesis.
print()dict()input()int()len()
When we call one of these built-in functions, Python accesses and then executes the funtion’s source code stored elsewhere in the Python environment.
For example, you can see the source code for the
print()function, contained in bltinmodule.c file in Python’s source code.
Using print() as an example:
The function definition is contained elsewhere in Python’s source code
We call the function using its name
print()We pass some kind of input to the function (i.e.
print("Hello world"))Some functions have an output or return value
