Can you pass a variable to the import function of python?

Question

i create a python file via the "with open()" method and now i would like to import the file but the filename should be variable.

filename = "Test"
with open(filename + ".py", "w+") as file:
    file.write("def main():
pass")

Now at a other line in the skript i would like to import the python script called like filename. But you cant do something like:

import filename

because then python searches for a python script called "filename". but in this example it should import "Test.py". Any suggestions?

You want the built in import function

new_module = __import__(modulename)

so...

filename = "Test"
with open(filename + ".py", "w+") as file:
    file.write("def main():
pass")
new_module = __import__(filename)
