DATA TYPES IN PYTHON
What are DATA TYPES ?
Data types are classified in the following types which I will explain you in a simple way in detail.
So so let's see the types of data in Python-:
- Number Type
- None type
- Sequence type
- Set type
- Mapping type
First I want you to see the given table of data types.
Let me explain you all the data types in Python briefly-:
Numeric Type -:
Numeric Type data store the numeric value, like 100,100.9, 200.99 etc.
Numbers in Python are classified into three types-:
- Integer
- Floating point number
- Complex numbers
Let us check the the different type of numeric type in Python-:
Integers-:
Integers are the positive and negative values which do not have decimal point in it.
Learning tip -: an integer in Python can be of any length.
For example-: 122, 133, 436 etc.
Boolean came under integers.
Boolean-:
Boolean data type represent one of the two possible values eighter true or false.
Learning tip-: A Boolean true value is non zero, non null, non empty.
Floating point Numbers-:
Floating point numbers are the positive and negative numbers which have decimal point in it.
Learning tip-:the fractional part of a floating point number can also be 0 (zero).
For example-: 133.0, 123.8, 546.2 etc.
Complex Numbers-:
Complex numbers are the combination of real and imaginary, which are present in the form of x+yj.
Where x is real and y is imaginary.
Note-: x and y are always the floating point integer.
For example -:
2+5j, 4-3j etc.
In Python -:
>>> x=2+5j
>>> print(x.real,x.imag)
2.0 5.0
None Type-:
What is None in Python?
This is a special data type with a single value and it is used to signify the absence of value evaluating to false in a situation.
For example-:
>>> value1=20
>>> value2=None
>>> value1
20
>>> value2
>>>
Sequence Type -:
 |
Under Sequence Type there comes-:
- String
- Tuples
- Lists
String-:
String is represented by (str), which is a sequence of characters that can be a combination of numbers letters and special characters enclosed within quotation marks.
Quotation mark ( " " ) define the starting and ending of string which are not printed on the screen.
For Example-:
print("Hello World")
Sets-:
A set in Python is unordered collection which is unindexed, and they are written with curly brackets in Python.
For example-:
set={"hello","world","welcome"}
Mapping-:
Dictionary-:
Python dictionary is an unordered collection of items for each item is a key value pair.
