How to use Data Type in Python – A Data Type is a data classification that tells the interpreter how the programmer will use the data. Data types in Python are as follows:
DATA TYPES FUNCTION NOTE EXAMPLE int Integer Declare an integer 10 or 1024 float Float Declare a number that has a comma 2.11 or 56.90 str String Declare characters or sentences enclosed by ” or ‘ signs “Hello Python, let’s learn Python programming”
‘Hello Python, let’s learn Python programming’bool Boolean Declare True if it is true and the value is 1
Declare False if it is false and has a value of 0True or False hex Hexadecimal Expresses a hexadecimal number (base 16) 8f3 or a1 complex Complex Expressing pairs of real and imaginary numbers 3 + 3x list List Declare various data types in an array and their contents can be changed [‘john’, 18, 71.2] tuple Tuple Declare various data types in an array and their contents cannot be changed (‘john’, 18, 71.2) dict Dictionary Declare various data types in an array that have labels along with their values and their contents can be changed {‘name’:’john’, ‘age’:18, ‘height’:71.2}
How to view Python data types:
If you don’t know what a variable stores data for, to find out you can simply use thetype(variable name)command. Then the data type of the variable will appear.
1. How to use Integer
To be able to use Integers in Python, the command form is like this:
x = 10
print(x)
type(x)The result is:
10
int
2. How to use Float
This is the same as integers. The command is as follows:
x = 10.2
print(x)
type(x)The result is:
10.2
float
3. How to use String
To use strings in python, characters must be enclosed in either two quotation marks (” “) or one quotation mark (‘ ‘).
For example:
x = 'Hello Python'
y = "Hello Python"
print(x)
print(y)The result is:
Hello Python
Hello PythonIn addition to writing strings, python can also perform string manipulation. We created a separate page to provide a good reading experience, see here.
4. How to Use Boolean
Boolean will return only True or False expression of a condition.
Example:
print('Python' == 'python')
print('Python' == 'Python')
print('Python' == "Python")
print(20 == 20)
print(10 > 20)
print(10 < 20)The result is:
False
True
True
True
False
True
5. How to use Hexadecimal
To use hexadecimal, the basic function used is hex(). That will return the value to be hexadecimal. But it’s different if the input is integer, float or ascii.
a. Integer using hex()
Example:
x = 20
print(hex(x))The result is:
0x14b. Float using float.hex()
If you want to see the hexadecimal data of a float, then the function is float.hex()
Example:
x = 20.2
print(float.hex(x))The result is:
0x1.4333333333333p+4c. ASCII using hex(ord(‘ascii val’))
If you want to see the hexadecimal value of an ASCII value, the function used is hex(ord('ascii val'))
Example:
x = 'a'
print(hex(ord(x)))
y = 'b'
print(hex(ord(y)))The result is:
0x61
0x62Hopefully this article is useful.
