Python - Read Files

Open a File on the Server :

Assume we have the following file, located in the same folder as Python:

freedomfile.py

WELCOME TO FREEDOM TUTORIALS
FREEDOM TUTORIALS IS THE BEST TUTORIALS AMONG THE BEST ONES.
IT LENDS INFORMATION ABOUT ALL THE COURSES BETTER ENOUGH.
    

To open the file, use the built-in open() function.

The open() function returns a file object, which has a read() method for reading the content of the file:

f = open("freedomfile.py", "r")
print(f.read())

Read Only Parts of the File :

By default the read() method returns the whole text, but you can also specify how many characters you want to return:

Return the 5 first characters of the file:

f = open("freedomfile.py", "r")
print(f.read(15))

Read Lines :

We can return one line by using the readline() method.

Read one line of the file :

f = open("freedomfile.py", "r")
print(f.readline())


========o/p========

By calling readline() two times, you can read the two first lines:

Read two lines of the file:

f = open("freedomfile", "r")
print(f.readline())
print(f.readline())

Close Files :

It is a good always to close the file when we are done with it.

f = open("freedomfile.py", "r")
print(f.readline())
f.close()

Note: You should always close your files, in some cases, due to buffering, changes made to a file may not show until you close the file.
