Import Python Script Into Another?

Solution 1:

It depends on how the code in the first file is structured.

If it's just a bunch of functions, like:

# first.py
def foo(): print("foo")
def bar(): print("bar")

Then you could import it and use the functions as follows:

# second.py
import first

first.foo()    # prints "foo"
first.bar()    # prints "bar"

# second.py
from first import foo, bar

foo()          # prints "foo"
bar()          # prints "bar"

or, to import all the names defined in first.py:

# second.py
from first import *

foo()          # prints "foo"
bar()          # prints "bar"

Note: This assumes the two files are in the same directory.

It gets a bit more complicated when you want to import names (functions, classes, etc) from modules in other directories or packages.

It's worth mentioning that (at least in python 3), in order for this to work, you must have a file named __init__.py in the same directory.
