Python had a lot of features built in for handling files.

Using the open fuction in Python we can read the files. The open() function returns a stream object. Here we are going to take a look at the methods and attributes available.

Opening a file

file = open(filename,encoding='utf-8')

Here I have specified the utf-8 encoding, you can use any of the other encodings which are supported by Python.

Attributes

file.name - returns the file name.

Name is the attribute of the file ,which will return the name of the file that you have opened.

file.encoding - returns the encoding of the file

file.mode - returns the mode, read or write.

Reading all lines

file.readlines() - reads all lines of the files

Reading first 5 character

file.read(5) - returns first 5 characters

Seeking

Syntax :

file.seek(position)

Example :

file.seek(0) - seeking to first position.

Finding the current position

file.tell() - tells the current position.

Closing the file stream

file.close() - Closes the file stream.

Checking whether the file is closed or not

file.closed - returns True or False based on the status of the file.

This is the sample file used for this example

sample.txt
