Python standard library: built-in functions hex (x) and pythonhex

This function is used to convert a hexadecimal string representation of an integer object, such as the 0x format. If the object is not an integer, define a method ___ index _ () to return an integer. If you want to convert the result of this function to the integer type, you must use the int () function and the base number is 16. In addition, if the floating point number is converted to hexadecimal notation, float. hex () is used for conversion, rather than this function.

Example:

# Hex () print (hex (20) print (hex (128) print (hex (0x55) print (hex (-127 ))

The output result is as follows:

0x14

0x80

0x55

-0x7f
