Python Bisect: Insert items into a list in sorted order

Python Bisect: Exercise-3 with Solution

Write a Python program to insert items into a list in sorted order.

Sample Solution:

Python Code:

import bisect
# Sample list
my_list = [25, 45, 36, 47, 69, 48, 68, 78, 14, 36]

print("Original List:")
print(my_list)
sorted_list = []
for i in my_list:
    position = bisect.bisect(sorted_list, i)
    bisect.insort(sorted_list, i)
print("Sorted List:")
print(sorted_list)

Sample Output:

Original List:
[25, 45, 36, 47, 69, 48, 68, 78, 14, 36]
Sorted List:
[14, 25, 36, 36, 45, 47, 48, 68, 69, 78]

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")
