HI,

sorry for asking i really tried but i couldn't know what should i do

When I run the following code:

from sys import argv
script, addingfile = argv[0],argv[1]

def print_all(k):
    print k.read()

usingfile = open(addingfile, "r+")

usingfile.write("i want to make it write in the file then print the file")

print_all(usingfile)

print "Done!"

see the following result:

I tried changing the code to this:

from sys import argv
script, addingfile = argv[0], argv[1]

def print_all(k):
    k.write("i want to make it write in the file then print the file")
    print k.read()

usingfile = open(addingfile, "r+")

print_all(usingfile)

print "Done!"

Modes 'r+', 'w+' and 'a+' open the file for updating (reading and writing); note that 'w+' truncates the file. Append 'b' to the mode to open the file in binary mode, on systems that differentiate between binary and text files; on systems that don’t have this distinction, adding the 'b' has no effect

! bug in windows !bug specific to Windows

usingfile=open(addingfile,"rb+")

still the same problem but i will try

i Tried many times again

my last code was

from sys import argv
script,addingfile=argv[0],argv[1]

usingfile=open(addingfile,"rb+")

usingfile.write("i want to write in the file then print the file")


def rewind(k):
     k.seek(0)


rewind(usingfile)

def print_all(k):
    print k.read()




print_all(usingfile)

print"Done!"

i will try again to know it (y)

i will read but after trying again (y)

i hope i will write the answer

i should type Seek between write & Read i tried before

but i will see what the problem where should i type seek !

script, addingfile = argv[0],argv[1]

def print_all(k):
     k.seek(0)
     print k.read()

usingfile = open(addingfile, "r+")

usingfile.write("i want to make it write in the file then print the file")



print_all(usingfile)

print "Done!"

from sys import argv
script, addingfile = argv[0],argv[1]

def print_all(k):
     k.write("i want to make it write in the file then print the file")
     k.seek(0)
     print k.read()

usingfile = open(addingfile, "r+")



print_all(usingfile)

print "Done!"

i will try again !

Never Give Up !

Yeaaaah !!!

from sys import argv
script, addingfile = argv[0],argv[1]

def print_all(k):
     k.write("i want to make it write in the file then print the file")
     k.seek(0)
     print k.read()

usingfile = open(addingfile, "w+")



print_all(usingfile)

print "Done!"

but i should type ("w+")

w+ : Opens a file for both writing and reading. Overwrites the existing file if the file exists. If the file does not exist, creates a new file for reading and writing

r+ : Opens a file for both reading and writing. The file pointer will be at the beginning of the file.

i can't type r+ !!!

(The file pointer will be at the beginning of the file)

i type seek(0) so r+ should run without problem !

The file pointer i will read about it

i will try that :) u think now i can go to the next tutorial ?
