Python: Find the indices of elements of a given list, greater than a specified value

Python List: Exercise - 205 with Solution

Write a Python program to find the indices of elements of a given list, greater than a specified value.

Sample Solution:

Python Code:

def test(lst, value):
    result = [i for i,val in enumerate(lst) if val > value]
    return result
nums = [1234, 1522, 1984, 19372, 1000, 2342, 7626]
print("\nOriginal list:")
print(nums)
val = 3000
print("Indices of elements of the said list, greater than",val)
print(test(nums,val))
nums = [1234, 1522, 1984, 19372, 1000, 2342, 7626]
print("\nOriginal list:")
print(nums)
val = 20000
print("Indices of elements of the said list, greater than",val)
print(test(nums,val))

Sample Output:

Original list:
[1234, 1522, 1984, 19372, 1000, 2342, 7626]
Indices of elements of the said list, greater than 3000
[3, 6]

Original list:
[1234, 1522, 1984, 19372, 1000, 2342, 7626]
Indices of elements of the said list, greater than 20000

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")
