Python hex() Method with Examples

Python / By

In the previous article, we have discussed Python float() Method with Examples
hex() Method in Python:

The hex() function converts the given number to a hexadecimal value.

The prefix 0x is always present in the returned string.

Syntax:

hex(number)

Parameters

The hex() function only accepts one argument.

x – integer number (either an int object or a __index__() method that returns an integer)

Return Value:

The hex() function converts an integer to its corresponding hexadecimal number and returns it as a string.

The hexadecimal string returned begins with the prefix 0x, indicating that it is in hexadecimal form.

Examples:

Example1:

Input:

Given Number = 20

Output:

The given number's{ 20 } Hexadecimal Value =  0x14
The hex() function Return Type = <class 'str'>

Note:

The prefix 0x denotes that the outcome is a Hexadecimal string.

Example2:

Input:

Given Number = 4.5

Output:

The given float number's{ 4.5 } Hexadecimal Value =  0x1.2000000000000p+2

hex() Method with Examples in Python

Method #1: Using Built-in Functions (Static Input)

1)

Approach:

  • Give the number as static input and store it in a variable.
  • Pass the given number as an argument to the hex() function to get the hexadecimal value of a given number.
  • Store it in another variable.
  • Print the given number’s Hexadecimal Value.
  • Print the Return Type of hex() Function using the type() method by passing the hex(given number) as an argument to it.
  • The Exit of the program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numbr = 20
# Pass the given number as an argument to the hex() function to get the
# hexadecimal value of a given number.
# Store it in another variable.
hexadeciml_valu = hex(gvn_numbr)
# Print the given number's Hexadecimal Value.
print("The given number's{", gvn_numbr,
      "} Hexadecimal Value = ", hexadeciml_valu)
# Print the return Type of hex() Function using the type() method by passing
# the hex(given number) as an argument to it.
print("The hex() function Return Type =", type(hex(gvn_numbr)))

Output:

The given number's{ 20 } Hexadecimal Value =  0x14
The hex() function Return Type = <class 'str'>
2)Hexadecimal Value of a floating-point Number

Approach:

  • Give the number as static input and store it in a variable.
  • Pass the given number as an argument to the hex() function and apply float to the result to get the hexadecimal value of a given float number.
  • Store it in another variable.
  • Print the given float number’s Hexadecimal Value.
  • The Exit of the program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numbr = 4.5
# Pass the given number as an argument to the hex() function and apply float
# to the result to get the hexadecimal value of a given float number.
# Store it in another variable.
hexadeciml_valu = float.hex(gvn_numbr)
# Print the given float number's Hexadecimal Value.
print("The given float number's{", gvn_numbr,
      "} Hexadecimal Value = ", hexadeciml_valu)

Output:

The given float number's{ 4.5 } Hexadecimal Value =  0x1.2000000000000p+2

Method #2: Using Built-in Functions (User Input)

Approach:

  • Give the number as user input using the int(input()) function and store it in a variable.
  • Pass the given number as an argument to the hex() function to get the hexadecimal value of a given number.
  • Store it in another variable.
  • Print the given number’s Hexadecimal Value.
  • Print the Return Type of hex() Function using the type() method by passing the hex(given number) as an argument to it.
  • The Exit of the program.

Below is the implementation:

# Give the number as user input using the int(input()) function and store it in a variable.
gvn_numbr = int(input("Enter some random number = "))
# Pass the given number as an argument to the hex() function to get the
# hexadecimal value of a given number.
# Store it in another variable.
hexadeciml_valu = hex(gvn_numbr)
# Print the given number's Hexadecimal Value.
print("The given number's{", gvn_numbr,
      "} Hexadecimal Value = ", hexadeciml_valu)
# Print the return Type of hex() Function using the type() method by passing
# the hex(given number) as an argument to it.
print("The hex() function Return Type =", type(hex(gvn_numbr)))

Output:

Enter some random number = 50
The given number's{ 50 } Hexadecimal Value = 0x32
The hex() function Return Type = <class 'str'>
2)Hexadecimal Value of a floating-point Number

Approach:

  • Give the number as user input using the float(input()) function and store it in a variable.
  • Pass the given number as an argument to the hex() function and apply float to the result to get the hexadecimal value of a given float number.
  • Store it in another variable.
  • Print the given float number’s Hexadecimal Value.
  • The Exit of the program.

Below is the implementation:

# Give the number as user input using the float(input()) function and store it in a variable.
gvn_numbr = float(input("Enter some random number = "))
# Pass the given number as an argument to the hex() function and apply float
# to the result to get the hexadecimal value of a given float number.
# Store it in another variable.
hexadeciml_valu = float.hex(gvn_numbr)
# Print the given float number's Hexadecimal Value.
print("The given float number's{", gvn_numbr,
      "} Hexadecimal Value = ", hexadeciml_valu)

Output:

Enter some random number = 7.5
The given float number's{ 7.5 } Hexadecimal Value = 0x1.e000000000000p+2
