10 Essential Python Tips And Tricks For Programmers

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.

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
