Reading text from a file 

In order to read and write into a file, we will use the open() built-in function to open the file. The open() function creates an file_object object. What is an object?  You will understand in  Chapter 11, Class and Objects.  The Syntax is given as:

file_object = open(file_name ,access_mode)

The first argument,file_name, specifies the filename that you want to open. The second argument, access_mode, determines in which mode the file has to be opened, that is, read, write, append, and so on. 

The read() method

Now we will read a file by a program. The access mode for reading is r.

Let's take the sample of a text file containing famous quotes:

Sample file

I have saved the preceding file with the name sample1.txt.

Let's write a readfile.py program to read the earlier file: 

file_input = open("sample1.txt",'r')
all_read = file_input.read()
print all_read
file_input.close() 

In the given code, first we created a file_input file object, then we called file_input.read() to read...
