4. Print The File Path Of Imported Modules.
import os import socket print (os) print (socket) |
Output:
<module 'os' from '/usr/lib/python3.5/os.py'> <module 'socket' from '/usr/lib/python3.5/socket.py'>
5. Use Of Enums In Python.
class MyName: Geeks, For, Geeks = range ( 3 ) print (MyName.Geeks) print (MyName.For) print (MyName.Geeks) |
Output:
2 1 2
6. Return Multiple Values From Functions.
def x(): return 1 , 2 , 3 , 4 a, b, c, d = x() print (a, b, c, d) |
Output:
1 2 3 4
7. Find The Most Frequent Value In A List.
test = [ 1 , 2 , 3 , 4 , 2 , 2 , 3 , 1 , 4 , 4 , 4 ] print ( max ( set (test), key = test.count)) |

n = 2 a = "GeeksforGeeks" print (a * n) |
Output:
GeeksforGeeksGeeksforGeeks
10. Checking if two words are anagrams
from collections import Counter def is_anagram(str1, str2): return Counter(str1) = = Counter(str2) # or without having to import anything def is_anagram(str1, str2): return sorted (str1) = = sorted (str2) print (is_anagram( 'geek' , 'eegk' )) print (is_anagram( 'geek' , 'peek' )) |
