Python File I/O: Write a List content to a file

Python File I/O: Exercise-12 with Solution

Write a Python program to write a list content to a file.

Sample Solution:-

Python Code:

color = ['Red', 'Green', 'White', 'Black', 'Pink', 'Yellow']
with open('abc.txt', "w") as myfile:
        for c in color:
                myfile.write("%s\n" % c)

content = open('abc.txt')
print(content.read())

Sample Output:

Red                                                                                                           
Green                                                                                                         
White                                                                                                         
Black                                                                                                         
Pink

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")
