Python Programming 19. Read From a Text File
This is the 19th in a course of computer science video lessons introducing programming with Python. In this video lesson, and the next one of the series, you will learn how to write Python programs that work with text files. This video covers reading data from a text file into a python program (the next video covers writing data into a text file). In this lesson you will learn how to open and close a read only text file. You will learn how to read the entire text file at once into a variable, you will learn how to read a specified number of characters from the text file into a variable, and you will learn how to read one line of text from a text file into a variable. You will also learn how to use a while loop to read a text file line by line, and how to use a for loop to do the same thing. In addition you will see how to search a text file for a particular piece of data.
