Python: Convert a byte string to a list of integers
Python Basic: Exercise-94 with Solution
Write a Python program to convert a byte string to a list of integers.
Sample Solution-1:
Python Code:
x = b'Abc'
print()
print("\nConvert bytes of the said string to a list of integers:")
print(list(x))
print()
Sample Output:
Convert bytes of the said string to a list of integers: [65, 98, 99]

Sample Solution-2:
Python Code:
S = "The quick brown fox jumps over the lazy dog."
print("Original string:")
print(S)
nums = []
print("\nConvert bytes of the said string to a list of integers:")
for chr in S:
nums.append(ord(chr))
print(nums)
Sample Output:
Original string: The quick brown fox jumps over the lazy dog. Convert bytes of the said string to a list of integers: [84, 104, 101, 32, 113, 117, 105, 99, 107, 32, 98, 114, 111, 119, 110, 32, 102, 111, 120, 32, 106, 117, 109, 112, 115, 32, 111, 118, 101, 114, 32, 116, 104, 101, 32, 108, 97, 122, 121, 32, 100, 111, 103, 46]

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")
