### Python hex() Function

Python hex() function is used to generate hex value of an integer argument. It takes an integer argument and returns an integer converted into a hexadecimal string. In case, we want to get a hexadecimal value of a float then use float.hex() function. The signature of the function is given below.

Signature

• hex (integer)

Parameters

integer: It is an integer value to be converted into a hex string.

Return

Let’s see some examples of hex() function to understand it’s functionality.

Python hex() Function Example 1

A simple example to get the hexadecimal value of integer decimals.

• # Python hex() function example
# Calling function
result = hex(1) # integer value
result2 = hex(342)
# Displaying result
print(result)
print(result2)

Output:

• 0x1
0x156

Python hex() Function Example 2

It takes only integer argument if we pass other, it throws an error to the console.

• # Python hex() function example
# Calling function
result = hex(1.5) # float value
# Displaying result
print(result)

Output:

• TypeError: ‘float’ object cannot be interpreted as an integer

Python hex() Function Example 3

To get hex value of float, use float.hex(). It does not throw any error. See the example below.

• # Python hex() function example
# Calling function
result = float.hex(1.5) # float value
result2 = float.hex(-238.15) # float value
# Displaying result
print(result)
print(result2)

Output:

• 0x1.8000000000000p+0
-0x1.dc4cccccccccdp+7
