If you do not store the code in a file on the device, it is lost after reset. There are many tools to copy files between your PC and the Micropython device, like rhshell, ampy, webrepl, upycraft, ... Most Micropython devices have an small internal file system in which you can store your scripts, and execute them with:
import myfile
iIf your file is called for instance "myfile.py"
