Python built-in Method - hex()

The hex() method in Python is a built-in function that returns a hexadecimal string representation of an integer.

The syntax for hex() is as follows:

hex(x)

Here, x is the integer to be converted to a hexadecimal string.

For example:

x = 255
hex_str = hex(x)
print(hex_str)  # Output: 0xff

In the example above, we define an integer x with the value of 255. We use the hex() function to convert x to a hexadecimal string, which is then stored in the hex_str variable. We then print the hex_str variable, which outputs the hexadecimal string representation of the integer 255.

The hex() function is useful when you need to represent an integer in a more compact or more readable format, such as when encoding binary data or generating unique identifiers.

Note that the hex() function only works with integers. If you need to convert other types of data to hexadecimal strings, such as byte arrays or bitstrings, you will need to use other functions or libraries.
