How to Open a File in Python

Python is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. Here is the instruction to tell you how to open a file in Python.

#open a file for read only
myfile = open(‘myfile.txt’, ‘r’)
