Just a Little BIT
Welcome to an intro level explanation of bitwise operations in Python!
Bitwise operations might seem a little esoteric and tricky at first, but you’ll get the hang of them pretty quickly.
class Fruit(object):
“””A class that makes various tasty fruits.”””
def __init__(self, name, color, flavor, poisonous):
self.name = name
self.color = color
self.flavor = flavor
self.poisonous = poisonous
def description(self):
print “I’m a %s %s and I taste %s.” % (self.color, self.name, self.flavor)
def is_edible(self):
if not self.poisonous:
print “Yep! I’m edible.”
else:
print “Don’t eat me! I am super poisonous.”
lemon = Fruit(“lemon”, “yellow”, “sour”, False)
lemon.description()
lemon.is_edible()

{Is there need to re-define everything??}
my_list = [i**2 for i in range(1,11)]
# Generates a list of squares of the numbers 1 – 10
f = open(“output.txt”, “w”)
for item in my_list:

f.close()

with open(“text.txt”, “w”) as textfile:
textfile.write(“Success!”)
with open(“text.txt”, “w”) as my_file:
