python

2. Python is an interpreted language used for various
purposes.
It includes :
1.software development.
2.Mathematics
3.System scripting
-Web development(server side)
4.Conduct data analytics

3. › Python is the most easiest language because their syntax
is similar to English language.
› For eg.
› In order to print hello world :
› The code is print(“hello world”)

4. Python shell
Pycharm
Sublime
Spider
Atom
PyDev
Jupiter notebook

5. › Django
› Flask
› Bottle
› Cherrypy
› Dash
› Cubicweb
› Falcon

6. › If
› If else
› While
› Break and continue
› Range
› List
› Boolean logic
› For
› Dict
› Set
› tuple

7. a=input(“is it raining”)
if a==‘yes’:
print(“take an umbrella”)
else:
Print(“put on a hat”)

8. › i=1
› while i<10:
› print(i)
› i=i+1

9. › i=1
› while i<7:
› i+=1
› if i==3:
› continue
› print(i)
› i=1
› while i<7:
› print(i)
› if i==3:
› break
› i+=1

10. › Python datatypes are of 2
types:
--mutable :list, dictionary,
sets
--immutable:String, Tuple,
numbers

11. fruits=["apple", "pineapple", "orange"]
fruits.append("kiwi")
fruits.insert(2,"banana")
del fruits[1]
fruits.pop(0)
fruits.remove("orange")
print(fruits)
print(len(fruits))
print(fruits.index("banana"))
print(fruits[-1])

12. num=list(range(3,10,3))
print(num)

13. for i in range(10):
if i==5:
break
print(i)
else:
print(“am else part”)
Used for iterating over a
sequence.
for i in “quadraplus”:
print(i)

14. › Eg:
› def my_fun(age):
› print(“my age is: “)
› x=int(input(“enter your age”)
› y=int(input(“enter your age”)
› my_fun(x)
› my_fun(y)
› Functions in Python:
A function is a block of
organized, reusable code
that is used to perform a
single, related action.
Functions provide better
modularity for your
application and a high
degree of code reusing.
As you already know, Python
gives you many built-in
functions like print(),
etc. but you can also create
your own functions. These
functions are called
user-defined functions.

15. def add(a,b):
return a+b
result=add(22,33)
print(result)
› def add(a,b):
› print(a+b)
› x=int(input(“enter a value”)
› y=int(input(“enter another
value”)
› add(x+y)

17. › Dictionary
› Dictionary function(get)
› Tuple
› List comprehension
› List slice
› set
› String formatting
› String function and
numeric function

18. › Single inheritance
› Multilevel inheritance
› Multiple inheritance
› Operator overloading
› recursion

19. › If we wanted to search a
particular pattern then by
using regular epression we
can find out
