![ List is an ordered sequence of items. It is one of the
most used data type in Python and is very flexible. All
the items in a list do not need to be of the same type.
Items separated by commas are enclosed within
brackets [ ].
List are mutable, meaning, value of elements of a list
can be altered.
For example : [“neha”,102,1.1]](https://image.slidesharecdn.com/pythondatatype-200123041441/85/Python-data-type-6-320.jpg)
![ Tuple is an ordered sequence of items same as list.The
only difference is that tuple are immutable. Tuples
once created cannot be modified.
Tuples are used to write-protect data and are usually
faster than list as it cannot change dynamically.
It is defined within parentheses () where items are
separated by commas.
We can use the slicing operator [] to extract items but
we cannot change its value.
For example: (‘a’, ‘e’, ‘I’, ‘o,’ ‘u’)](https://image.slidesharecdn.com/pythondatatype-200123041441/85/Python-data-type-7-320.jpg)
![ String is sequence of Unicode characters. We can use
single quotes or double quotes to represent strings.
Multi-line strings can be denoted using triple quotes’’’
.
Like list and tuple, slicing operator [ ] can be used with
string. Strings are immutable .
for example:“hello world ”etc .](https://image.slidesharecdn.com/pythondatatype-200123041441/85/Python-data-type-8-320.jpg)

- 2. DATA TYPES IN PYTHON a) PYTHON NUMBER b) PYTHON LIST c) PYTHON TUPLE d) PYTHON STRING e) PYTHON SET f) PYTHON DICTIONARY
- 3. Every value in Python has a data type. Since everything is an object in Python programming, data types are actually classes and variables are instance (object) of these classes. There are various data types in Python. Some of the important types are listed below
- 4. Integers, floating point numbers and complex numbers falls under Python numbers category. They are defined as int, float and complex class in Python. We can use the type() function to know which class a variable or a value belongs to and the is instance() function to check if an object belongs to a particular class
- 5. Integer can be of any length, it is only limited by the memory available. EXAMPLE: 8 etc . A floating point number is accurate up to 15 decimal places. Integer and floating points are separated by decimal points. 1 is integer, 1.0 is floating point number. A complex number are of the form a+bj where a and b are floats and j represents square root of -1 .a is real part of a number and b is the imaginary part . Example : 2+3 j etc.
- 6. List is an ordered sequence of items. It is one of the most used data type in Python and is very flexible. All the items in a list do not need to be of the same type. Items separated by commas are enclosed within brackets [ ]. List are mutable, meaning, value of elements of a list can be altered. For example : [“neha”,102,1.1]
- 7. Tuple is an ordered sequence of items same as list.The only difference is that tuple are immutable. Tuples once created cannot be modified. Tuples are used to write-protect data and are usually faster than list as it cannot change dynamically. It is defined within parentheses () where items are separated by commas. We can use the slicing operator [] to extract items but we cannot change its value. For example: (‘a’, ‘e’, ‘I’, ‘o,’ ‘u’)
- 8. String is sequence of Unicode characters. We can use single quotes or double quotes to represent strings. Multi-line strings can be denoted using triple quotes’’’ . Like list and tuple, slicing operator [ ] can be used with string. Strings are immutable . for example:“hello world ”etc .
- 9. Set is an unordered collection of unique items. Set is defined by values separated by comma inside braces{ }.items in a set are not ordered. We can perform set operations like union, intersection on two sets. Set have unique values. They eliminate duplicates.
- 10. Dictionary is an unordered collection of key-value pairs. It is generally used when we have a huge amount of data. Dictionaries are optimized for retrieving data. We must know the key to retrieve the value. In Python, dictionaries are defined within braces {} with each item being a pair in the form key:value. Key and value can be of any type.
