Python: Remove the ANSI escape sequences from a string

Python Regular Expression: Exercise-45 with Solution

Write a Python program to remove the ANSI escape sequences from a string.

Sample Solution:-

Python Code:

import re
text = "\t\u001b[0;35mgoogle.com\u001b[0m \u001b[0;36m216.58.218.206\u001b[0m"
print("Original Text: ",text)
reaesc = re.compile(r'\x1b[^m]*m')
new_text = reaesc.sub('', text)
print("New Text: ",new_text)

Sample Output:

Original Text:          google.com 216.58.218.206                                                             
New Text:       google.com 216.58.218.206

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")
