Goal¶
This notebook introduces how to print "Hello, World!" on a CPU. It also covers basic Python functions, printing host information, and checking CPU details.
import hello
Required Modules for the Jupyter Notebook¶
Before running the notebook, we need to load the following modules.
Module: hello
Print 'Hello, World!' using CPU¶
To display a message in Python, we use the print() function. For example, lets print out Hello world!!! using print() function.
print('Hello world!!!!')
Defining a Function in Python¶
Next, we use the def keyword to define a function. Here's an example of a function that takes a name as an argument and prints it:
# Define a local function
def world2(name):
print(name)
# Call function
world2("mary")
mary
Using a Module Function¶
You can also call functions from imported modules. For example:
hello.greeting("good times")
Greetings, good times
hello.world("World.")
Hello, World.
Print out host information¶
!hostname
exp-1-04
check the CPU information¶
!lscpu
