Python: Split a list based on first character of word

Python List: Exercise - 40 with Solution

Write a Python program to split a list based on first character of word.

Sample Input:

word_list = ['be','have','do','say','get','make','go','know','take','see','come','think',
     'look','want','give','use','find','tell','ask','work','seem','feel','leave','call']
Python: Split a list based on first character of word

Sample Solution:-

Python Code:

from itertools import groupby
from operator import itemgetter

word_list = ['be','have','do','say','get','make','go','know','take','see','come','think',
     'look','want','give','use','find','tell','ask','work','seem','feel','leave','call']

for letter, words in groupby(sorted(word_list), key=itemgetter(0)):
    print(letter)
    for word in words:
        print(word)

Sample Output: 

a

come                                                                                                          
d

want

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")
