Python provides us many different ways to read and write to a file. Here we will see how to use them and how they works.

The easiest way to open a file is to use the python open() function. While opening a file in the same directory where the script is we use open('file1.txt', 'w'). To open a file file in specific directory we can provide the raw location link open(r'D:\python_files\file1.txt', 'w').

There are few options we can use while opening a file they are shown below:

Mode	Description
'r'	Opens a file in read only mode
'w'	Opens a file if already exist clears its contents, if not creates a new file
'x'	Creates a new file, error in case of file already exists
'a'	Opens file in append mode, If not exist creates a new file
't'	To open a file in text mode. Its a default mode
'b'	Open a file in binary mode
'+'	Open a file in both read and write mode.

Here is an example:

def f_w():
    infile = open('file1.txt', 'w')
    print(infile.read())
def f_x():
    infile = open('file2.txt', 'x')
    print(infile.read())
def f_a():
    infile = open('file3.txt', 'a')
    print(infile.read())
def f_t():
    infile = open('file4.txt', 't')
    print(infile.read())
def f_b():
    infile = open('file5.txt', 'b')
    print(infile.read())
def f_wp():
    infile = open('file6.txt', 'w+')
    print(infile.read())
def f_ap():
    infile = open("file7.txt", "a+")
    print(infile.read())

f_w()
f_x()
f_a()
f_t()
f_b()
f_wp()
f_ap()

Try the code and see what will be the output. Comment below if you found what will be the result.
