Python tips and tricks for beginners

Python is an interpreted, high-level and general-purpose programming language. Comparing to other programming languages python is so easy to learn. Python is a highly productive language. Python first appeared in 1991. So it has a mature developer community. Python can be used on almost all platforms. It can be used for web development, mobile apps development, game development, big data, machine learning, cloud computing, and so many other cases.

Here are some python coding tips and tricks for beginners.

1. Assigning multiple variables at once

Generally, in python, we assign variable like this

a = 25

b = 36

But we can assign multiple variables in one line like this

a, b, c = 21, 34, 54

Print statement can take unlimited arguments separated by comma like this

print(a, b, c)

2. Large number

You can easily split the large number with the underscore and it doesn't affect the value, and easy to read. Like

large_number = 99_99_99_999

3. Assign multi-line string in a variable

In python, if you declare a variable with a multi-line value it will take the first line. But if you want to declare a multi-line value in a variable you can do it with a backslash like this

str_value = "This is multi" \

 "line value"

Alternatively, you can do it with triple quotes. it will print the output multiple lines as you declared Like

str_value = '''This is multi

line value'''

If you want to print it out in one line you have to use a backslash like this

str_value = '''This is multi \

line value'''

4. Separate list item by the character in the same line

You can loop through your list item and show it in the same line separate by any given separator like this

mylist = ["c++", "python", "java", "kotlin"]

for l in mylist:

 print(l, end="\t\t")

But if you print something after the loop it will show the next to the loop items. like

for l in mylist:

 print(l, end="\t\t")

print('new test')

to clear it you have to put an empty print statement after the loop like this

for l in mylist:

 print(l, end="\t\t")


print('new test')

5. Ternary Operators

It is easy to write a simple if statement in one line by ternary operators. like this, if statement

fish_price = 50

money = 100

if(money > fish_price):

 print("You can buy")


 print("You can not buy")

to this

print( "You can buy" if money > fish_price else "you can not buy")

6. Removing duplicate item and keep one from the list

Duplicates item can be removed easily by using the set constructor like this

fruits = ["Apple", "Banana", "Orange", "Apple", "Coconut", "Apple"]

unique_fruits = list(set(fruits))


7. Simplify the if statement with multiple OR condition

It can easily simplify and clean the multiple or condition in an if statement like

fruits = "Apple"

if fruits == "Apple" or fruits == "Orange" or fruits == "Watermelon":

 print("I eat this")

to this

if fruits in ["Apple", "Orange", "Watermelon"]:

 print("I eat this")

8. Another way to clean if statement

if an if statement multiple comparisons/conditions exist like this

fruit = "Apple"

salad = "Cucumber"

drink = "7UP"

if fruit == "Apple" and salad == "Cucumber" and drink == "7UP":

 print("WoW Good Meal")

if you need to pass all condition you can write this like

conditions = [

 fruit == "Apple",

 salad == "Cucumber",

 drink == "7UP"


if all(conditions):

 print("WoW Good Meal")

if you need to implement or condition you can use any like this

if any(conditions):

 print("WoW Good Meal One Of This")

9. Flatten a 2D list

Generally, a 2D list can be flattened or convert as a single list like this

fruits = [ ["Apple", "Banana"], ["Coconut", "Orange"], ["Watermelon", "Mango", "Guava"]]

flat = []

for fruit in fruits:

 for f in fruit:



The easiest way to do this

flat = [f for fruit in fruits for f in fruit]


here the f is the value we keep/append to the list.
