#the way i learned it
#plus explanations
from sys import * #this is for making it more flexible
#so now we gotta open a file to write in
f = open("haha.txt", "w") # the w means WRITING
#now we gotta write something
f.write(str(argv[1])) # the str means change it into a string of letters
#argv[1] means it's the thing you type after the python run thing
#for example: "python run.py helo"
#now we gotta finish it
f.close()
#if you want to see whats in it...
f = open("haha.txt", "r") #r means READING
print(f.read()) # this prints what you wrote
#example input and output
# python run.py helo
