hex() function

hex() function in Python programming language is used to convert any type of representation of a number to hexadecimal. Hexadecimal numbers are represented with base 10. Representation of these numbers is done in a unique way it used numbers from 0 to 9 to represent the first 10 numbers and then uses A to F alphabets to represent numbers from 10 to 15.

Hexadecimal representation

Hexadecimal representation of a number is done using numbers from 0-9 and alphabets from A-F. Any representation of the number can be converted into hexadecimal by using hex() function. hex() function is an in-built function of python library. hex() function takes only one argument. As a representation of the number is passed in the function it returns the hexadecimal representation of the argument. Let’s have a look at python code to convert some number representation in hexadecimal format.

Python program to convert numbers to Hexadecimal format

#integer number
int_number = 14956
#converting number to hexadecimal
#using hex function
Hexa_number = hex(int_number)
print(str(Hexa_number) + ' is hexadecimal representation of number with base 10')


#binary number
bin_number = 0b101010
#converting binary number to hexadecimal
#using hex function
Hexa_number = hex(bin_number)
print(str(Hexa_number) + ' is hexadecimal representation of number with base 2')


#octal number
oct_number = 0o15437
#converting octal number to hexadecimal
#using hex function
Hex_number = hex(oct_number)
print(str(Hexa_number) + ' is hexadecimal representation of number with base 8')

Output:
0x3a6c is hexadecimal representation of number with base 10
0x2a is hexadecimal representation of number with base 10
0x1b1f is hexadecimal representation of number with base 10

In the above python program where we converted numbers with base 10, 2 and 8 in the hexadecimal format or number with base 16 we used the in-built hex() function. As the number enters the function it internally converts the number into the hexadecimal format and then using the print function we print it on the screen.

FAQ

How do you represent a hex in python?

To represent a hexadecimal value we use 0x in the prefix of the number. 0x before the number represents the number to be in a hexadecimal format. In python, we can convert any number in hexadecimal by using hex() function.

What is octal value in Python?

Number with base 8 is referred to as the octal number. When a number is represented with the prefix 0o then the number is considered as an octal number

How do you print a binary value in Python?

Binary numbers are numbers with base 2. These type of numbers can be represented with the prefix 0b. Any number can be converted to binary representation using bin() function.
