In this tutorial, you will work on the different file operations in Python. You will go over how to use Python to read a file, write to a file, delete files, and much more. File operations are a fundamental aspect of programming, and Python provides a robust set of tools to handle th...
In the above example, we are opening the file named ‘test.txt’ present at the location ‘C:/Documents/Python/’ and we are opening the same file in a read-write mode which gives us more flexibility. Example 2: fo = open(“C:/Documents/Python/img.bmp”, “rb+”) In the above e...
Functions in Python You use functions in programming to bundle a set of instructions that you want to use repeatedly or that, because of their complexity, are better self-contained in a sub-program and called when needed. That means that a function is a piece of code written to carry out...
