#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)
