Probably the greatest methods to check and apply your abilities with Python is by fixing coding challenges. You may study loads from books and on-line programs, however coding isn’t an armchair exercise. It’s important to write some code to make real progress.
Coding challenges are good for this. Coding challenges are small issues you’ll be able to remedy with code. Simply because they’re small doesn’t imply they gained’t put your information to the take a look at. Every bite-size problem will deal with abilities that you just’ll use later engaged on full software program initiatives.
On this article, we’ll provide you with 12 newbie Python coding challenges to get you began. Strive one or two a day to maintain your Python abilities sharp. And if you wish to proceed difficult your Python abilities, we’ll present you ways you are able to do that on the finish of the article.

High 12 newbie Python code challenges
These are beginner-level challenges, however you want to know the Python programming language to finish them. In case your Python abilities are somewhat rusty, take a look at Be taught Python 3 for a course that’s appropriate for novices.
You may code your options domestically when you have a improvement setting already arrange. If not, check out one of many many websites that may will let you execute Python code within the browser. And should you get caught, search Google for assist fixing the issue, however don’t do it too quickly. Give it your finest shot first.
1. Convert radians into levels
Write a perform in Python that accepts one numeric parameter. This parameter would be the measure of an angle in radians. The perform ought to convert the radians into levels after which return that worth.
Whilst you would possibly discover a Python library to do that for you, you must write the perform your self. One trace you get is that you just’ll want to make use of Pi with the intention to remedy this downside. You may import the worth for Pi from Python’s math module.
2. Kind a listing
Create a perform in Python that accepts two parameters. The primary can be a listing of numbers. The second parameter can be a string that may be one of many following values: asc, desc, and none.
If the second parameter is “asc,” then the perform ought to return a listing with the numbers in ascending order. If it’s “desc,” then the record ought to be in descending order, and if it’s “none,” it ought to return the unique record unaltered.
3. Convert a decimal quantity into binary
Write a perform in Python that accepts a decimal quantity and returns the equal binary quantity. To make this easy, the decimal quantity will all the time be lower than 1,024, so the binary quantity returned will all the time be lower than ten digits lengthy.
4. Depend the vowels in a string
Create a perform in Python that accepts a single phrase and returns the variety of vowels in that phrase. On this perform, solely a, e, i, o, and u can be counted as vowels — not y.
5. Cover the bank card quantity
Write a perform in Python that accepts a bank card quantity. It ought to return a string the place all of the characters are hidden with an asterisk besides the final 4. For instance, if the perform will get despatched “4444444444444444”, then it ought to return “4444”.
6. Are the Xs equal to the Os?
Create a Python perform that accepts a string. This perform ought to depend the variety of Xs and the variety of Os within the string. It ought to then return a boolean worth of both True or False.
If the depend of Xs and Os are equal, then the perform ought to return True. If the depend isn’t the identical, it ought to return False. If there are not any Xs or Os within the string, it must also return True as a result of 0 equals 0. The string can comprise any sort and variety of characters.
7. Create a calculator perform
Write a Python perform that accepts three parameters. The primary parameter is an integer. The second is likely one of the following mathematical operators: +, -, /, or . The third parameter may also be an integer.
The perform ought to carry out a calculation and return the outcomes. For instance, if the perform is handed 6 and 4, it ought to return 24.
8. Give me the low cost
Create a perform in Python that accepts two parameters. The primary ought to be the complete worth of an merchandise as an integer. The second ought to be the low cost proportion as an integer.
The perform ought to return the value of the merchandise after the low cost has been utilized. For instance, if the value is 100 and the low cost is 20, the perform ought to return 80.
9. Simply the numbers
Write a perform in Python that accepts a listing of any size that incorporates a mixture of non-negative integers and strings. The perform ought to return a listing with solely the integers within the unique record in the identical order.
10. Repeat the characters
Create a Python perform that accepts a string. The perform ought to return a string, with every character within the unique string doubled. In case you ship the perform “now” as a parameter, it ought to return “nnooww,” and should you ship “123a!”, it ought to return “112233aa!!”.
11. Convert lowercase to uppercase
For this problem, create a Python perform that accepts a string. The perform ought to return a string, with every lowercase character within the unique string returned as uppercase characters. In case you ship the perform “goodbye” as a parameter, it ought to return “GOODBYE”.
12. Add dots
Write a perform in Python that accepts a string. The perform ought to return a string and add “.” in between every letter. For instance, should you ship the perform “abilities” as a parameter, it ought to return “s.ok.i.l.l.s”.
