Python String Exercises: Insert a string in the middle of a string

Sample Solution:-

Python Code:

def insert_sting_middle(str, word):
	return str[:2] + word + str[2:]

print(insert_sting_middle('[[]]', 'Python'))
print(insert_sting_middle('{{}}', 'PHP'))
print(insert_sting_middle('<<>>', 'HTML'))

Sample Output: 

[[Python]]

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")
