x, y = 30, 40
print(x, y)
x, y = y, x
print(x, y)
Output:
30 40

2. Reversing a string in Python
a = “ShahriarRulz”
print(“Reverse is”, a[::-1])
Output:
Reverse is zluRriarhahS
3. Create a single string from all the elements in list
a = [“Shahriar”, “Rulz”]
print(” “.join(a))
Output:
Shahriar Rulz
4. Chaining Of Comparison Operators.
n = 10
result = 1 < n < 20
print(result)
result = 1 > n <= 9
print(result)
Output:
True
False
5. 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’>
6. Use of Enums In Python.
class MyName:
Shahriar, For, Shahriar = range(3)
print(MyName. Shahriar)
print(MyName.For)
print(MyName. Shahriar)
Output:
2
1
2
7. 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
8. 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
9. Check The Memory Usage Of An Object.
import sys
x = 1
print(sys.getsizeof(x))
Output:
28
10. Print string N times.
n = 2
a = “ShahriarRulz”
print(a * n)
Output:
ShahriarRulz ShahriarRulz
11. 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(‘zeek’, ‘eezk’))
print(is_anagram(‘zeek’, ‘peek’))
Output:
True
False
