The document provides an overview of basic Python operations on lists and strings, showcasing examples of list creation, sorting, and manipulation, along with tuple and set characteristics. It demonstrates various string methods such as joining, splitting, and case conversion. Overall, it serves as a tutorial for fundamental data operations in Python programming.

2. Array

3. List = Array
numbers = [ "zero", "one", "two", "three", "FOUR"
]

4. List = Array
numbers = [ "zero", "one", "two", "three", "FOUR"
]
numbers[0]
>>> zero
numbers[4] numbers[-1]
>>> FOUR >>> FOUR
numbers[-2]
>>> three

5. Multi Dimension List
numbers = [ ["zero", "one"],["two", "three",
"FOUR" ]]
numbers[0]
>>> ["zero", "one"]
numbers[0][0] numbers[-1][-1]
>>> zero >>> FOUR
len(numbers)
>>> 2

6. Sort List
primes = [ 11, 5, 7, 2, 13, 3 ]

7. Sort List
primes = [ 11, 5, 7, 2, 13, 3 ]
primes.sort()
>>> [2, 3, 5, 7, 11, 13]

8. Sort List
primes = [ 11, 5, 7, 2, 13, 3 ]
>>> primes.count(13)
1
>>> primes.index(3)
5
>>> primes.insert(4,40)

9. Sort List
>>> primes.pop()
>>> primes.remove(9)
>>> primes.reverse()
>>> primes.extend([10,20,30])
>>> primes[2:5]

10. Sort List
Primes = [ 11, 5, 7, 2, 13, 3 ]
>>> primes + [10,20,30]
>>> primes.extend([10,20,30])
>>> primes[2:5]

11. Sort List
names = [ "Shrini", "Bala", "Suresh",
"Arul"]
names.sort()
>>> ["Arul", "Bala","Shrini","Suresh"]
names.reverse()
>>> ["Suresh","Shrini","Bala","Arul"]

12. Mixed List
names = [ "Shrini", 10, "Arul", 75.54]
names[1]+10
>>> 20
names[2].upper()
>>> ARUL

13. Mixed List
names = [ "Shrini", 10, "Arul", 75.54]
names[1]+10
>>> 20
names[2].upper()
>>> ARUL

14. Append on List
numbers = [ 1,3,5,7]
numbers.append(9)
>>> [1,3,5,7,9]

15. Tuplesimmutable

16. names = ('Arul','Dhastha','Raj')
name.append('Selva')
Error : Can not modify the tuple
Tuple is immutable type

17. Sets

18. String

19. name = 'Arul'
name[0]
>>>'A'
myname = 'Arul' + 'alan'
>>> 'Arulalan'

20. name = 'This is python string'
name.split(' ')
>>>['This','is','python','string']
comma = 'Shrini,Arul,Suresh'
comma.split(',')
>>> ['Shrini','Arul','Suresh']
split

21. li = ['a','b','c','d']
s = '-'
new = s.join(li)
>>> a-b-c-d
new.split('-')
>>>['a','b','c','d']
join

22. 'small'.upper()
>>>'SMALL'
'BIG'.lower()
>>> 'big'
'mIxEd'.swapcase()
>>>'MiXwD'

23. String
‘
‘’
’’’
“””

24. String
formatting
