I have a code that I wish to split apart into multiple files. In Matlab, one can simply call a *.m file, and as long as it is not defined as anything, in particular, it will just run as if it were part of the called code. Example (edited):
test.m (Matlab)
function [] = test()
... some code using variables ...
test2
test2.m (Matlab)
... some more code using same variables ...
Calling test runs the code in the test as well as the code in test2.
Is there a similar way for python, to put ... some more code ..., into an external file, that will simply be read as if it is in the file that it is called from?
Yes, you can split your files in different modules and import what you need.
for example:
#file 1 -- filename1.py --
myvar = 42
def test_func():
print("Hello!")
#file 2 -- use_filename1.py --
#first method
import filename1
filename1.test_func() #prints "Hello!"
print (filename1.myvar) #prints 42
#or use this method
from filename1 import test_func #Only import the function directly into current namespace
test_func() #prints "Hello"
print (myvar) #Exception (NameError) #because we didnt import this one
#or this one which have a behavior like first one.
from filename1 import *
test_func() #prints "Hello"
print(myvar) #prints 42
you can refer to python documents for more information:

Yes, you can split python code into multiple files. And use the import mechanism to get access that code again. It works in a different way than the example you sketch above. Which by the way is very confusing: You define a function test, and call a function test2; what is that supposed to illustrate?
