#File Objects

##The Basics:
#f = open("test.txt", "r")
#f = open("test.txt", "w")
#f = open("test.txt", "a")
#f = open("test.txt", "r+")
#print(f.name)
#print(f.mode)
#f.close()

##Reading Files:
#with open("test.txt", "r") as f:
	#pass

	##Small Files:
	#f_contents = f.read()
	#print(f_contents)

	##Big Files:
	#f_contents = f.readlines()
	#print(f_contents)

    ###With the extra lines:
	#f_contents = f.readline()
	#print(f_contents)
	#f_contents = f.readline()
	#print(f_contents)

	###Without the extra lines:
	#f_contents = f.readline()
	#print(f_contents, end = '')
	#f_contents = f.readline()
	#print(f_contents, end = '')

	###Iterating through the file:
	#for line in f:
		#print(line, end = '')

	###Going Back....:
	#f_contents = f.read()
	#print(f_contents, end = '')

	###Printing by characters:
	#f_contents = f.read(100)
	#print(f_contents, end = '')
	#f_contents = f.read(100)
	#print(f_contents, end = '')
	#f_contents = f.read(100)
	#print(f_contents, end = '')

	###Iterating through small chunks:
	#size_to_read = 100
	#f_contents = f.read(size_to_read)
	#while len(f_contents) > 0:
		#print(f_contents)
		#f_contents = f.read(size_to_read)

	###Iterating through small chunks, with 10 characters:
	#size_to_read = 10
	#f_contents = f.read(size_to_read)
	#print(f_contents, end = '')
	#f.seek(0)
	#f_contents = f.read(size_to_read)
	#print(f_contents, end = '')
	#print(f.tell())
	#while len(f_contents) > 0:
		#print(f_contents, end = '*')
		#f_contents = f.read(size_to_read)
#print(f.mode)
#print(f.closed)
#print(f.read())


##Writing Files:
###The Error:
#with open("test.txt", "r") as f:
	#f.write("Test")

###Writing Starts:
#with open("test2.txt", "w") as f:
	#pass
	#f.write("Test")
	#f.seek(0)
	#f.write("Test")
	#f.seek("R")

##Copying Files:
#with open("test.txt", "r") as rf:
	#with open("test_copy.txt", "w") as wf:
		#for line in rf:
			#wf.write(line)

#Copying the/your image:
###The Error
#with open("bronx.jpg", "r") as rf:
	#with open("bronx_copy.jpg", "w") as wf:
		#for line in rf:
			#wf.write(line)

###Copying the image starts, without chunks:
#with open("bronx.jpg", "rb") as rf:
	#with open("bronx_copy.jpg", "wb") as wf:
		#for line in rf:
			#wf.write(line)

###Copying the image with chunks:
#with open("bronx.jpg", "rb") as rf:
	#with open("bronx_copy.jpg", "wb") as wf:
		#chunk_size = 4096
        #rf_chunk = rf.read(chunk_size)
        #while len(rf_chunk) > 0:
            #wf.write(rf_chunk)
            #rf_chunk = rf.read(chunk_size)
