The direction variable is named as direction in Unix or route in home windows -Python-courses-Unix is case touchy-Python-courses- windows isn-Python-courses-t always-Python-courses-. In Mac OS, the installer handles the course info. To invoke the Python interpreter from any specific listing, you should add the Python listing on your direction. placing course at Unix-Python-courses-Linux to add the Python listing to the direction for a specific consultation in Unix − in the csh shell − type setenv direction -Python-courses-$route-Python-courses--Python-courses-usr-Python-courses-neighborhood-Python-courses-bin-Python-courses-python-Python-courses- and press enter. inside the bash shell -Python-courses-Linux-Python-courses- − type export course=-Python-courses-$route-Python-courses--Python-courses-usr-Python-courses-local-Python-courses-bin-Python-courses-python-Python-courses- and press enter. inside the sh or ksh shell − kind path=-Python-courses-$route-Python-courses--Python-courses-usr-Python-courses-neighborhood-Python-courses-bin-Python-courses-python-Python-courses- and press input. notice − -Python-courses-usr-Python-courses-neighborhood-Python-courses-bin-Python-courses-python is the path of the Python directory setting course at windows to feature the Python directory to the path for a selected session in home windows − at the command activate − kind course %route%-Python-courses-C-Python-courses-Python and press input. observe − C-Python-courses-Python is the course of the Python directory

Exercise 202

Write a program in python as a function which examines whether two sets are disjoint or not. If the two sets are disjoint, the function must return True and False if not.


def examineSet(E , F):
# using and initializing a counter
counter = 0
# we test if there is a common element of E and F and incrementing the counter
for x in E:
if x in F:
counter +=1
if counter > 0:
return True
return False

# Testing algorithm
E = {"Java", "Python", "Javascript", "C ++", "C #"}
F = {"VB.ET", "Java", "Kotlin", "Python"}
print(examineSet(E , F)) # display True

G = {"Zend Framework", "Django", "Flask"}
H = {"AngularJS", "Ionic Framework" , "ReactJS"}
print(examineSet(G , H)) # display False
