This lesson will teach a practical application of Python's print and input methods. We will demonstrate the print() statement by outputting fixed data to the screen, and then demonstrate how input() can output
In Python, you can use files to read and write data. The open() function opens a file, and the read() and write() functions read and write data to the file. The with statement ensures that the file is closed properly, even if an error occurs. For example, the following code opens...

Output: $ python io_pickle.py ['apple', 'mango', 'carrot'] How It Works To store an object in a file, we have to first open the file in write binary mode and then call the dump function of the pickle module. This process is called pickling. Next, we retrieve the object using ...
Python Input and Output With this topic, we begin our series of Python Practice tutorials. Every tutorial describes a specific topic with examples. A problem statement at the end of each tutorial will assess your understanding. Introduction
And this is how you can handle the error in the python program. Conclusion: Here, we have learned about how to make input only accept numbers in python, convert the input data into an integer, and handle errors using the try-except statement....
