Pictorial Presentation:

Python: Find the string consisting of all the words whose lengths are prime numbers.

Sample Solution:

Python Code:

#License: https://bit.ly/3oLErEI

def test(strs):
    return " ".join(strs for strs in strs.split() if is_prime(len(strs))) 
def is_prime(n):
    return n > 1 and all(n % j for j in range(2, int(n ** 0.5) + 1))
strs = "The quick brown fox jumps over the lazy dog."
print("Original list of numbers:")
print(strs)
print("Words whose lengths are prime numbers in the said string:")
print(test(strs))
strs = "Omicron Effect: Foreign Flights Won't Resume On Dec 15, Decision Later."
print("\nOriginal list of numbers:")
print(strs)
print("Words whose lengths are prime numbers in the said string:")
print(test(strs))

Sample Output:

Original list of numbers:
The quick brown fox jumps over the lazy dog.
Words whose lengths are prime numbers in the said string:
The quick brown fox jumps the

Original list of numbers:
Omicron Effect: Foreign Flights Won't Resume On Dec 15, Decision Later.
Words whose lengths are prime numbers in the said string:
Omicron Effect: Foreign Flights Won't On Dec 15,

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")
