Python Math: Convert an integer to a 2 byte Hex value
Python Math: Exercise-80 with Solution
Write a Python program to convert an integer to a 2 byte Hex value.
Sample Solution:-
Python Code:
for i in range(1, 10):
print(i,'-->',format(i, '#04x'))
Sample Output:
1 --> 0x01 2 --> 0x02 3 --> 0x03 4 --> 0x04 5 --> 0x05 6 --> 0x06 7 --> 0x07 8 --> 0x08 9 --> 0x09

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
