10 Awesome Python Tips and Tricks You Should Learn

Python has experienced impressive growth as compared to the other language. so here are the tips and tricks that help to improve the performance of your Python programming and solving ability. Here are the 10 awesome python tips and tricks you must learn today.

1. Fulfilled all conditions without declared all conditions in if.

# For one or two conditions 

viewers = 1000
likes = 500
if viewers >= 1000 and likes >= 500:
    print(" Good luck ")

#Output
Good luck

If you have one or two conditions, you can use the above example programs

# For more than ten conditions

viewers = 2000
likes = 700
conditions = [ viewers >= 1000,likes >= 500]

if all(conditions):
    print(" Good luck ")

#Output
Good luck

Suppose if you have more than ten conditions, you can create a list and use all() to perform AND operation (fulfilled all conditions). If you didn’t get it compare two examples side by side to understand clearly.

2. Fulfilled at least one conditions without declared all conditions in if.

# For one or two conditions 

viewers = 1000
likes = 500
if viewers >= 1000 or likes >= 700:
    print(" Good luck ")

#Output
Good luck

# For more than ten conditions

viewers = 2000
likes = 700
conditions = [ viewers >= 1000,likes >= 500]

if any(conditions):
    print(" Good luck ")

#Output
Good luck

You can create a list and use any() to perform OR operation (fulfilled at least one condition). If you didn’t get it compare two examples side by side to understand clearly.

3. Swapping two values without using temp

# Swapping two values 
a,b = 5,7

# Swapping without using temp variable
a,b = b,a
print('a =' , a ,'b =' , b)

#Output
a = 7 b = 5

4. Remove Duplication in list ( Easy Way )

#Remove duplicates in List

Org_list = [1,2,3,4,2,3,5]
alter_list = list(set(Org_list))
print(alter_list)

#Output
[1, 2, 3, 4, 5]

We already know that set returns the values without duplicates. So, we convert a list to set and again set to list (Typecasting).

5. Reverse String

# Simple way to reverse string 

Blog = "Iterathon" [::-1]
print(Blog)

#Output
nohtaretI

We have a lot of ways to reverse a string using python. But, most of the people didn’t know this.

6. Find The Most Frequent Value In a List

#Find most frequent value in a list

list = [2,4,6,2,5,3,2,1,7]
print(max(set(list), key = list.count))

#Output
2

7. Generating squares of first 10 natural numbers (using comprehensions )

# Normal format

squares = [ ]
for x in range(1,11):
    s = x ** 2
    squares.append(s)
print (squares)

#Output 
[1, 4, 9, 16, 25, 36, 49, 64, 81, 100]

List comprehension is the simplest way of creating a sequence of elements that fulfilled the condition

#List comprehension

squares = [ x ** 2 for x in range(1,11) ]
print (squares)

#Output
[1, 4, 9, 16, 25, 36, 49, 64, 81, 100]

8. Concatenating Strings

#join strings

characters = ['I', 'T', 'E', 'R', 'A', 'T', 'H', 'O', 'N']
Blog = ''.join(characters)
print(Blog)

#Output
ITERATHON

9. Colored Text using Python

Before doing this, you must have termcolor module to access this example. Link for Download termcolor: https://pypi.org/project/termcolor/

#Text with colors

from termcolor import colored
print(colored("ITERATHON", "red"))

#output
ITERATHON

10. Measuring Execution Time using Python

time module is an inbuilt module so you can access it without installing any extra packages or modules

#calculate Execution time

import time
start = time.time()
end = time.time()
total = end - start
print("Total Execuation time is", total)

#Output
Total Execuation time is 2.384185791015625e-07
