Why it's not working ?

Question

# FILE HANDLING

file = open("index.html", "a");

file.write("<!-- Hello, World! -->")
file.close()

print(file.read())

Answer 1

Add>>> file=open("index.html","r")
between file .close() line and
print() line.
!! Don't forget to call read mode("r")

Answer 2

How can you read a file after closing it ? And the read method also depends on the mode in which file is opened .
