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])

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

def is_anagram(str1, str2):
