#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)
