Python String: Exercise-85 with Solution

Write a Python program to convert a given Bytearray to Hexadecimal string.

Sample Solution:-

Python Code:

def bytearray_to_hexadecimal(list_val):
     result = ''.join('{:02x}'.format(x) for x in list_val)  
     return(result)

list_val = [111, 12, 45, 67, 109] 
print("Original Bytearray :")
print(list_val)
print("\nHexadecimal string:")
print(bytearray_to_hexadecimal(list_val))

Sample Output:

Original Bytearray :
[111, 12, 45, 67, 109]

Hexadecimal string:
6f0c2d436d

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")
