How to read a file and display the contents with Python. This sample code reads and outputs the contents of a file using Python. This is a very simple code sample for reading in a file and displaying it.
#!/usr/bin/env python forme = "f.txt"; # Read a file and print the contents to the terminal. with open(forme) as f: content = f.read() print content;
Admins-iMac-230:DBZ admin$ python read.py ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost
Here is what the output of this script looks like. I am printing the contents of a copy of the hosts file on an iMac.
You may also put this into a function; this allows you to call the code later.
#!/usr/bin/env python forme = "f.txt"; def readfile(): # Read a file and print the contents to the terminal. with open(forme) as f: content = f.read() print content; readfile()
As you can see, this is a very easy programming task.
Here is another way to achieve this.
#!/usr/bin/env python import os forme = "f.txt"; def readfile(): response = os.system("cat " + forme) readfile()
Using the cat command within python. Either way is good, but will not work on Windows.
