Hi, may i know how the code will look like if i decide to use

read_and_write_file = open(“text.txt”, “r+”)

I don’t understand how read_file in this block of code works since it was buffered (not sure if I’m saying that right) before the new data was written to the file.

write_file = open(“text.txt”, “w”)
read_file = open(“text.txt”, “r”)

write_file.write(“Not closing files is VERY BAD.”)

print read_file.read()

Wouldn’t the read_file at “print read_file.read()” still only contain the old data from before the write?
