Python is one of the most preferred languages out there. Its brevity and high readability makes it so popular among all programmers. 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.
Python3
x, y = 10, 20print(x, y)x, y = y, xprint(x, y) |
10 20 20 10
2. Reversing a string in Python
Python3
a = "GeeksForGeeks"print("Reverse is", a[::-1]) |
Reverse is skeeGroFskeeG
3. Create a single string from all the elements in list
Python3
a = ["Geeks", "For", "Geeks"]print(" ".join(a)) |
Geeks For Geeks
4. Chaining Of Comparison Operators.
Python3
n = 10result = 1 < n < 20print(result)result = 1 > n <= 9print(result) |
True False
4. Print The File Path Of Imported Modules.
Python3
import osimport socketprint(os)print(socket) |
<module 'os' from '/usr/lib/python3.5/os.py'> <module 'socket' from '/usr/lib/python3.5/socket.py'>
5. Use Of Enums In Python.
Python3
class MyName: Geeks, For, Geeks = range(3)print(MyName.Geeks)print(MyName.For)print(MyName.Geeks) |
2 1 2
6. Return Multiple Values From Functions.
Python3
def x(): return 1, 2, 3, 4a, b, c, d = x()print(a, b, c, d) |
1 2 3 4
7. Find The Most Frequent Value In A List.
Python3
test = [1, 2, 3, 4, 2, 2, 3, 1, 4, 4, 4]print(max(set(test), key = test.count)) |
4
8. Check The Memory Usage Of An Object.
Python3
import sysx = 1print(sys.getsizeof(x)) |
28
9. Print string N times.
Python3
n = 2a = "Lazyroar"print(a * n) |
LazyroarLazyroar
10. Checking if two words are anagrams
Python3
from collections import Counterdef is_anagram(str1, str2): return Counter(str1) == Counter(str2)# or without having to import anythingdef is_anagram(str1, str2): return sorted(str1) == sorted(str2)print(is_anagram('geek', 'eegk'))print(is_anagram('geek', 'peek')) |
True False
11. Sorting the dictionary according to key and value
Python3
x={1:3,4:2,5:1,2:9}#sorting the dictionary according to valueprint(sorted(x.items(),key=lambda a:a[1]))#sorting the dictionary according to keyprint(sorted(x.items(),key=lambda a:a[0])) |
