Python programming language is very easy to learn for students and professionals.
A file is a container in computer storage devices used for storing data.
When we want to read from a file, we need to open it first. When we are done, it needs to be closed so that the resources that are tied with the file are freed.
Hence, in Python, a file operation takes place in the following order:
1. Open a file
2. Read the file
3. Close the file
1. Opening File in Python
In Python, we use the open() method to open a file.
Example:
file1 = open("test.txt") # default read mode
file1 = open("test.txt", "r") # read mode
2. Reading Files in Python
After we open a file, we use the read() method to read its contents.
Example:
read_content = file1.read()
3. Closing Files in Python
When we are done with performing operations on the file, we need to properly close the file.
Closing a file will free up the resources that were tied with the file. It is done using the close() method in Python.
Example:
file1.close()
