Applied Computational Thinking with Python
By :
In this section, we're going to take a look at how to handle files, data, and iteration with Python. This will give us information on how to use an algorithm to open, edit, and run already-existing Python files or new files. With iteration, we'll learn how to repeat lines of code based on some conditions, limiting how many times or under what conditions a section of the algorithm will run for. We'll start with files first.
In Python, the main function associated with files is the open() function. If you are opening a file in the same directory, you can use the following command line:
fOpen = open('filename.txt')
If the file is in another location, you need to find the path for the file and include that in the command, as follows:
fOpen = open('C:/Documents/filename.txt')
There are a few more things we can tell the program to do in addition to opening the file. They...
