# Python Interview Preparation:

Now,

A] Python 

• Python is high level programming language that was created by guido van rossum and first released in 1991

> Features

1. Easy to read syntax
2. Interpretation/ Interpreted
3. Cross-platform compatability
4. Large Standard Library: Data Exporting Analysis (numpy,pandas,matplotlib)
5. Extensive third Party libraries 

> Applications:

• Web Development, App, Games,Data Visualization

B] Python Datatypes:

1. Int
2. Float
3. String
4. Boolean
5. Complex
6. List
7. String
8. Tuple
9. Dictionary

>  Types :

A] Mutable Datatype :  Value inside object can be changed

B] Immutable Datatype : Value Can not Be changed

Eg: Datatypes

a) Mutable 

• List
• Dictionary
• Sets

b) Immutable

• Tuple
• String

C} Type casting

• Conversion of one datatype to another

String - Int => No

String - Float=> No

>  Summarize all list, set, tuple, dictionary

> List 

1. Mutable

2. []

3. Iteration : Slower

4. More Money

5. Ordered Collection

6. Has Duplicates

Tuple

1. Immutable

2. ()

3. Faster

4. Less Memory

5. Ordered Collection

6. No Duplicates

Set

1. Mutable

2. {}

3.

4.

5.Unorderd Collection

6. No Duplicates

Dictionary

1. Mutable

2. Key: Value

3. 

4.

5. Unordered 

6. Key- No Duplicates, Value :  Duplicates

E]  Functions  (Typing....)

> Functions of List

1. Append () : add element to end of list
2. Clear() :  remove all elements from list
3. Copy() : returns copy of list
4. Count() :  returns no.of 
5. Index()
6. Insert()
7. Pop()
8. Reverse()
9. Sort()
10. Remove()

> Functions of Tuple

3. Get()
4. Pop()
5. Keys()

> Functions of Set

1. Add()
2. Clear()
3. Copy()
4. Pop()
5. Remove()
6. Union
7. Update
