PYTHON- FILE HANDLING-READ FILE AND WRITE FILE.HOW TO HANDLE FILE AND HOW TO READ AND WRITE A FILE IN PYTHON


FIRST TAKE A VARIABLE(f ) AND THEN OPEN A FILE USING open() METHOD WHICH IS IN BUILT IN PYTHON.THIS OPEN () METHOD TAKE TWO PARAMETERS[f=open("",'')]:

 1.FILE NAME WITH PATH [f=open("file.txt",'')]

2.WHICH MODE YOU WANT TO USE. IF READ THEN GIVE 'r' IF WRITE GIVE 'w' OR IF YOU WANT TO OPEN FILE IN APPEND MODE THEN YOU WRITE 'w'.

    FOR READ --  f= open("file.txt",'r')
    FOR WRITE---  f=open("file.txt",'w')
    FOR APPEND---  f=open("file.txt",'a')

NOW THE CODE IS:   f=open("file.txt",'r')

IF YOU WANT TO READ THE FILE THEN YOU USE read() METHOD AND IF YOU WANT TO WRITE THE FILE YOU USE write() METHOD.

IN THIS CASE FOR READ YOU CAN USE f.read() AND WRITE YOU CAN USE f.write("YOUR TEXT WHICH YOU WANT TO WRITE ")

FULL CODE FOR READ:

f=open("file.txt",'r')
w=f.read()
print(w)

AND FOR WRITE:

f=open("file.txt",'w')

f.write("SUBSCRIBE PROGRAMMING FUN YOUTUBE CHANNEL.")

f.close()

THIS THE WAY TO READ AND WRITE IN A FILE ON PYTHON PROGRAMMING.
