Learn about file input and output in Python from "summary" of Python For Dummies by Stef Maruch,Aahz Maruch
File input and output is a crucial aspect of programming in Python. It allows you to read data from external sources such as files and write data to files. This capability is vital when working with large sets of data that need to be stored or processed. In Python, you can open a file using the `open()` function, which takes two arguments: the filename and the mode in which you want to open the file. When reading from a file, you can use the `read()` method to read the entire contents of the file into a single string. Alternatively, you can use the `readline()` method to read one line at a time. You can also loop over the file object to read each line individually. After you're done reading from a file, it's good practice to close the file using the `close()` method to free up system resources. When writing to a file, you can open the file in write mode using the `'w'` argument in the `open()` function. You can t...
