What the ? 😮 ( PLEASE HELP ) 😞

Question

def my_function(filename):
f = open(filename,"w")
f.write("hello world")
f.close()

print(my_function("hello.txt"))

file = open("hello.txt","r")

Answer 1

@Rick this is what I tried 😞 didn't work just showed none but I wrote and showed the content of the file

Answer 2

@Rick I tried to create the file with no content before I use the function but it the result was the same as the one in this code

Answer 3

file = open("newfile.txt", "w")
file.write("This has been written to a file")
file.close()

file = open("newfile.txt", "r")
print(file.read())
file.close()

Answer 4

Maybe you should print the file instead the function
