File Object Properties:
=======================

# File object and its properties

fp = open("abc.txt","w+")

print("File Name = ",fp.name)
print("The Mode of the file = ",fp.mode)
print("is file writeable?:",fp.writable())
print("is file readable?:",fp.readable())

print("is file closed?:",fp.closed)

fp.close()

print("is file closed?:",fp.closed)

===================================================
How to write the data into file:
================================
write()
=======
==> can allow to write the string (one line data).
Syntax:
	file-object.write("data")

writelines()
============
==> can allow to write the data in more lines.
Syntax:
	file-object.writelines(data)

# write operations

fp = open("abc.txt","w")

data = ["abc\n","def\n","ghi\n"]

fp.write("Hi\n")
# fp.write("Good Morning.\n")
# fp.write("Welcome To Ashok IT.")

fp.writelines("Hi")
fp.writelines("Good Morning.")
fp.writelines("Welcome to Ashok IT.")

fp.write(data)
fp.writelines(data)
============================================================
Reading the data from the file:
===============================
read():
======
	==> use to read the total data from the file.
	Syntax:
		file-object.read()
		file-object.read(n) # to read first 'n' characters of the file

readline()
===========
	==> to read only one line of data from file.
	Syntax:
		file-object.readline()

readlines():
============	
	==> can read all the lines of data in list format.
	Syntax:
		fp.readlines()

fp = open("abcd.txt","r+")

# writing the data

# data = ["Python\n", "Java\n", "C++\n", "C\n", "C#\n", "JavaScript"]
#
# fp.writelines(data)

# fd = fp.read()
# fd1 = fp.read(10)

print("The File data is = ")
# print(fd)
# print(fd1)

print(fp.readline())

# print(fp.readlines())

line = fp.readlines()

for i in line:
    print(i)

================================================
with Statement:
===============
==> can be used to define block of operations on the file using file pointer.
==> after all the operations, the with statement can close the file automatically (without writing close() explicitly.)

with open("abc.txt","w+") as fp:
    fp.write("Hi\n")
    fp.write("Good Morning.\n")
    fp.write("Welcome To Ashok IT.")

    print("THe Data = ",fp.read())

    print("Is file closed:",fp.closed)

print("Is file closed:",fp.closed)

=========================================================
tell():
=======
==> to know the current position of the file pointer, we can use "tell()".
Syntax:
	fp.tell()

fp = open("abc.txt","r")

print(fp.tell())

print(fp.read(3))

print(fp.tell())

print(fp.read(6))

print(fp.tell())

=========================================
seek():
======
==> can be used to move the file pointer from current position to any specified position.
Syntax:
	fp.seek(offset, fromwhere)

offset ==> number of characters 
fromwhere ==> three values
	0 ==> from the beginning ==> python supports this only  
	1 ==> from current position
	2 ==> from ending of the file

	fp.seek(offset, 0)
	fp.seek(offset)

fp = open("abc.txt","r")

print(fp.tell())

print(fp.read(3))

print(fp.tell())

print(fp.read(6))

print(fp.tell())

fp.seek(15)

print(fp.tell())

fp.seek(30)

print(fp.tell())
