Python: Display formatted text as output

Python String: Exercise-26 with Solution

Write a Python program to display formatted text (width=50) as output.

Sample Solution:-

Python Code:

import textwrap
sample_text = '''
  Python is a widely used high-level, general-purpose, interpreted,
  dynamic programming language. Its design philosophy emphasizes
  code readability, and its syntax allows programmers to express
  concepts in fewer lines of code than possible in languages such
  as C++ or Java.
  '''
print()
print(textwrap.fill(sample_text, width=50))
print()

Sample Output: 

 Python is a widely used high-level, general-                                                               
purpose, interpreted,   dynamic programming

readability, and its syntax allows programmers to                                                             
express   concepts in fewer lines of code than

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")
