So here are few of the tips and tricks you can use to bring up your Python programming game.

1. In-Place Swapping Of Two Numbers.




x, y = 10, 20
print(x, y)
x, y = y, x
print(x, y)
Output:
10 20
20 10

2. Reversing a string in Python




a = "GeeksForGeeks"
print("Reverse is", a[::-1])
Output:



Reverse is skeeGroFskeeG

3. Create a single string from all the elements in list




a = ["Geeks", "For", "Geeks"]
print(" ".join(a))
Output:
Geeks For Geeks

4. Chaining Of Comparison Operators.




n = 10
result = 1 < n < 20
print(result)
result = 1 > n <= 9
print(result)
Output:
True
False

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))
Output:
4

8. Check The Memory Usage Of An Object.




import sys
x = 1
print(sys.getsizeof(x))
Output:
28

9. Print string N times.




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'))    
Output:
True
False
