Here is a list of Python programming practices. The practice examples include arrays, lists, strings, searching and sorting, and more. Coding concerns are addressed in each code example. Let’s practice these codings regularly.

What is Python coding?

Python is a widely used high-level, dynamic, interpreted coding language. Its syntax allows learners to build ideas in some codes’ lines more than appropriate in codings like Java or C++.

Python supports imperative, object-oriented, procedural, and functional coding methods. It contains a robust kind system, automated memory management, and a large standard library.

Exercise and practice questions are the most reliable way for students to learn anything. This area is only for Python beginners to intermediates. These tasks help students improve their Python coding skills.

Let’s do some python practice

Let’s call them num1 and num2. To find the total of the two numbers, run a Python script.

Example:

num1 = 6; num2 = 1

7

num1 = 12 num2 = 5

17

In this Python tutorial, we will add two numbers. Initially, ask them to write two numerals. The data is kept in the variables num1 and num2. Then the variables num1 and num2 are added together using the arithmetic operator +.

This Python function adds two numbers:

1:

12 num1

15 num2

1 + 2 Equals

# Output values printing

“The sum of 0 and 1 is 2”.format(num1, num2, add)

Output:

12 + 15 = 27.

Calculate the sum of an array of integers.

As in:

arr[] = 2, 4, 6

12

2+4+6=12

arr[] = 10, 20, 30, 40

100 output

Method 1:

# Python application to add elements in an array

_sum(arr,n)

# sum using sum

# built-in sum()

return(sum(arr))

driver func

arr=[]

10-20-30-40

# length of the array

(len) (arr)

_sum (arr,n)

# sum

(‘The specified array’s addition is’, ans)

Output:

Method 2:

# Python summation practice

# of array elements

driver func

arr =

10-20-30-40

# sum() is a built-in Python method that sums

# the list’s variables, set and returns

Variables

= sum (arr)

# sum

Output:

Python code to swap two items in a list

Suggested a Python program that swapped two components within a list.

As in:

Pos1 = 2, pos2 = 4

[10, 40, 30, 20]

Pos1 = 4, pos2 = 10

[2, 10, 6, 8, 4]

#1: Simple swap

The programmer can swap the component locations as they are identified.

# Python switch component code

# at a location

Function swap

list, pos1, pos2 swapPositions:

list[pos1], list[pos2]

list

# Driver func

[10, 20, 30, 40]

1, 2 = 2, 4

swapLocations(List, pos2-1)

Output:

10 40 30 20

Method #2: Using list.pop()

Pop the component at pos1 and save it. Also, save the component at pos2 to another value. Now put the two popped components back where they were.

# Python switch component code

# at a location

Function swap

List (pos1, pos2) swapLocation

# a list of components

list.pop (pos1)

list.pop (pos2-1)

# putting them near each other

pos1, second ele

first ele, pos2

list

# Driver func

[10, 20, 30, 40]

1, 2 = 2, 4

print(list, pos1-1, pos2-1))

Output:

10 40 30 20

Using a tuple variable

Put the pos1 and pos2 components in a tuple value. Remove components with pos2 and pos1 on the list. A list’s two positions will now be swapped.

Change components in Python

# a place

Function swap

List (pos1, pos2) swapLocation

# Keeping the two parts

# in a tuple values get

get = list[pos1]

# detach them

get[pos2], get[pos1]

list

# Code

[10, 20, 30, 40]

1, 2 = 2, 4

swapLocations(List, pos2-1)

Output:

10 40 30 20

#4: Using comma assignment

# Python switch component code

# at a certain place

swapLocations(list,1,2):

list[pos1], list[pos2]

list

# Code

[10, 20, 30, 40]

1, 2 = 2, 4

swapLocations(List, pos2-1)

Output:

10 40 30 20

Python technique for reversing a string

This post has a string, and it needs to be reversed?

As in:

Statalytica Python Practice Program Input: str

str = “program practice python statanalytica”

# Reverse words in a string

rev sentence:

Initialize a string with words.

sentence.split(‘)

# reverse the divided string list and connect with space

‘.join(reversed(words))

reverse sentence

>>>>>>>>>>>>>>>

‘statanalytica python practice program’

rev sentence (input)

Output:

“python statalytica programming practice”

Python linear search practice code

Execute a function to discover a component x in an array arr[].

As in:

arr[] = 5, 10, 15, 20, 25, 30, 35

40, 45, 50

30 x

6

Index 6 has component x.

arr[] = 5, 10, 15, 20, 25, 30, 35

40, 45, 50

2x

-1

No component x in arr[].

A simple method is a linear search, i.e.

• Analyze x one by one with each component of arr[].

• When x obtains a component value, pass the index.

||||||||||||||||

As in:

Finding a component in a Python array/list

# using the ‘in’ operator.

# If x is arr:

# arr.index (x)

# To do Linear Search in Python

# Search x in arr[]

# If x matches, return its position.

# else -1

x, arr:

range(len(arr)):

as x = arr[i]

I

-1
