How to run a python class, and ow to run R script on linux

Here is a python class:



    class Student:
         def   __init__(self, name, age):
                 self.name=name
                 self.age=age
         def   say_hello(self):
                print(self.name, "say hello")

And, to run it, type the following in the same program:

alice=Student("Alice", 16)

alice.say_hello()

Do not forget the parenthesis.

Save the program as python1.py

And on linux run:

python python1.py

And you will see on the screen:

('Alice', 'say hello')

Here is another example:

class Base1:

def __init__(self,x,y):

self.x=x

self.y=y

def add1(self):

z=self.x+self.y

print(z)

def main():

foo=Base1(1,2)

foo.add1()

if __name__=="__main__":

main()

And you will see 3 was printed on screen.

To run an R program on linux, write an R program and save as rprog1.R

a=c(1,2,3)

for ( i in 1:3)

{ print(i)}

And run Rscript rprog1.R on linux, you will see:

[1] 1

[2] 2

[3] 3
