# We will learn about opening and editing files from python program

# open file using open function

# other argument to open function specifies mode, r = reading, r+ = read and write, a = append to file and so on.

# The other way we can open file is to use context

# the advantage of using context is that we don't need to close the file, it will take care of it

# f_handle = open('test.txt', 'r')

#with open('test.txt', 'r') as f_handle:

#print(f_handle.read())

# Instead of reading whole file contents using read we can read line by line using readlines or readline functions

#f_contents = f_handle.readlines()

#print(f_contents, end='')

#f_contents = f_handle.readline()

#print(f_contents, end='')

#for line in f_handle:

# print(line, end='')

# We are using write function to create copy of the existing file

with open('test.txt', 'r') as rf:

with open('test_copy.txt', 'w') as wf:

for line in rf:

wf.write(line)

# print(f_handle.name)

# print(f_handle.mode)

# print(f_handle.read())

# f_handle.close()
