readline ()) #call infile.read() print ( infile. #Create a variable for the file name filename = 'Plates_output_simple.csv' #Open the file infile = open ( filename, 'r' ) #Print the first two lines of the file print ( infile. Mixing these commands can have some unexpected results. Infile.readlines() will read all of the lines into a list, where each line of the file is an item in the list. Infile.readline() will read in one line at a time (each time you call this command, it reads in the next line). Infile.read() will read in the entire file as a single string of text. There are a variety of commands that allow us to read in data from files. Which we can read in data, and data for the variable holding the contents of the file. In these examples, we will use filename for the text string containing the file name, infile for the open file object from Is the opened file object, and which variable contains the read-in data. Variable names each time will make it easier for you to keep track of which variable is the name of the file, which variable It is a good idea to develop some consistent habits about the way you open and read files. Use consistent names to make your code clearer Once we have read the data in the file into our variable data, we can treat it like any other variable in our code. read () #Print the data in the file print ( data ) #close the file infile. #Create a variable for the file name filename = 'Plates_output_simple.csv' #This is simply a string of text #Open the file infile = open ( filename, 'r' ) # 'r' says we are opening the file to read, infile is the opened file object that we will read from #Store the data from the file in a variable data = infile. Here is an example of opening, reading, and closing a file. Finally, to gain any information from the book, you have to read the words (the read Then, you have to go and get it off the shelf and open theīook up (the open function). First, you have to go to theĬatalog or database to find out which book you need (the filename). You can think of these three steps as being similar to checking out a book from the library.
