The tasks are designed in such a way that the complexity increases as users progress through the tasks. One can't move forward until the current task is completed. Previously submitted tasks can be viewed if he/she wants but can't be worked on again.\n\n- `teachcode` expects you to have a GitHub account. Make sure that you create one if you don't have one. [Learn more - Github Signup](https://docs.github.com/en/github/getting-started-with-github/signing-up-for-a-new-github-account)\n- Navigate to the directory of your choice and type in `teachcode init`.\n- Choose your track. Currently, we provide two tracks, Python and Javascript\n- Enter your name. We ask for your name mainly for greeting purpose.\n- Enter your GitHub username.\n- Enter your GitHub personal token with repo access. [Learn more - GitHub Personal Token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)\n- Now type in `cd teachcode-solutions`.\n- Type in `teachcode fetchtask`.\n- Hurray :tada: you've got your first task.\n- Type in your solution for the task in the file `task1.py` (opted learning track) using any code editor of choice. We recommend using [VS Code](https://code.visualstudio.com/)\n- Now type in `teachcode submit` to submit your solution.\n- Enter your Git credentials when prompted. [Learn more - Git Credentials](https://docs.github.com/en/github/getting-started-with-github/getting-started-with-git)\n- Fetch the next task with `teachcode fetchtask`.\n\n## Available Commands\n\n| command | description |\n| ------------------------- | ------------------------------------------------------------------------------------- |\n| teachcode init | Initializes all the tasks |\n| teachcode fetchtask [key] | Fetches the task correponding to the key if provided (defaults to the very next task) |\n| teachcode submit | Submits the current task |\n| teachcode showkeys | Lists all the keys associated with the submitted tasks |\n\n## Contributing\n\nContributions of any kind are welcomed. Make sure that you go through these [guidelines](https://teachcode.madlabs.xyz/guide/contributing.html).\n\n### How should I write a commit message?\n\nThis project uses [Commitlint](https://github.com/conventional-changelog/commitlint/#what-is-commitlint) to check if the commit messages meet the [conventional commit format](https://www.conventionalcommits.org/en/v1.0.0/).\n\nThe full pattern is:\n\n```sh\ntype(scope?): subject #scope is optional\n\nbody? #body is optional\n\nfooter? #footer is optional\n```\n\nFollowing that pattern, your commit messages should look like these:\n\n```sh\nfeat: activate open collective\n```\n\n```sh\nchore: correct typo\n\nIt should be \"guest\" and not \"gest\"\n```\n\n```sh\nrefactor(cli): drop support for node 6\n\nBREAKING CHANGE: you will need to update your node version to keep using this CLI\nThis closes #123\n```\n\n### How should I name my branches?\n\nPrefix your branch names with `feat/`, `docs/` or `hotfix/` for feature proposals, documentation and bug fixes, respectively.\n\n## License\n\nLicensed under `GNU General Public License V3.0`.\n"

The tasks are designed in such a way that the complexity increases as users progress through the tasks. One can't move forward until the current task is completed. Previously submitted tasks can be viewed if he/she wants but can't be worked on again.\n\n- `teachcode` expects you to have a GitHub account. Make sure that you create one if that's not the case.\n- Navigate to the directory of your choice and type in `teachcode init`. After typing the command, the following window would appear in your terminal\n\n
\n\n\n\n
\n\n- Select the language of your choice and follow the instructions as prompted.\n\n
\n\n\n\n
\n\n- After entering your Github user token, you would get the following screen. Now type in `cd teachcode-solutions` followed by `teachcode fetchtask`.\n\n
\n\n- Hurray :tada: , you've got your first task.\n- Now you can find a `config.json` and `task1.py` (language of choice) file within the `teachcode-solutions` directory.\n\n
\n\n\n\n
\n\n- Open up your favorite editor and code up the solution.\n\n
\n\n\n\n
\n\n- Now type in `teachcode submit`.\n- Enter your Git credentials when prompted.\n- If the current solution satisfies all test cases, you'll get the key to proceed farther.\n- Now type in `teachcode fetchtask`. \n- Solve all 30 question, to complete the task \n\n\n*In case you want to revisit any of the previously submitted tasks, grab the associated key by typing in `teachcode showkeys` followed by `teachcode fetchtask `*\n- That's all folks, good luck :+1:\n\n\n\n"

Now install the dependencies with `npm install`\n4. Type in `npm link` which creates a symlink and thereby allowing `teachcode` to be accessed globally.\n5. Make your life changing changes.\n6. Ensure that your code is free from linting errors and is as per prettier conventions by typing in `npm run lint`.\n7. We use [commitlint conventional naming rules](https://www.npmjs.com/package/@commitlint/config-conventional#rules) for our commits, make sure that you follow them.\n8.

Make sure that you submit an issue first if you have something in mind that you're willing to work on.\n2. Follow a `rebase` strategy to update your remote branch with the latest changes.\n3. Prefix your branch names with `feat/`, `docs/` or `hotfix/` for feature proposals, docs-related and bug fixes, respectively.\n"

Return the square root and print it. Import math module and use sqrt(). \\n Pass the value 3364.\"\n },\n {\n \"task\": \"\\n Great work! You have reached the 20th Task!! \\n You have mastered the basics of modules. \\n Now let's move on to the next topic: Collection Data Types. \\n There are 4 collection datatypes. Let's begin with Lists. \\n A list is a collection which is ordered and which can be changed. \\n List elements are enclosed with Square Brackets []. Eg: randomlist = ['one','two'] \\n List stores the values in an order. It start with an index 0. \\n To access the first element in the list, you have to use list[0]. The first element is always stored in the index 0. \\n For traversing through a list, you can use a for loop. Eg: for i in list_name: \\n\\tprint(i) \\n Here's your task: \\n\\n Task 20 \\n Create a list with elements 1 to 10 and traverse through the list and print the even numbers.\"\n },\n {\n \"task\": \"\\nWow!

There are many operations that can be performed on Lists. \\n They are: \\n 1. Checking whether the element exists in the list using 'in' keyword. \\n 2. To determine length of the list using len() \\n 3. To add items using append() \\n 4. To insert at specific index using insert() \\n 5. To remove a particular element using remove(element) \\n 6. Pop() - Removes at specified index or by default, the last one. \\n 7. del keyword removes the specified index. \\n 8. clear() - Empties the whole list. \\n Here's your task.(Quite a hectic task!) \\n\\n Task 22 \\n Create a list with the values 'one', 'two', 'three'. Your task is to do the following: \\n 1. Search for the element one and print 'Found!' if found, else print 'Not Found!' \\n 2. Print the length of the list \\n 3. Add 'four' to the list using append() \\n 4. Insert 'five' at index 1 using insert() \\n 5. Remove 'one' from the list using remove() \\n 6. Remove the value at index 0 using pop() \\n 7. Delete the second element of the list using del \\n 8.

Now you have mastered the basics of Lists. \\n Let's go to the next one: Tuples. \\n A tuple is a collection which is ordered and unchangeable. In Python tuples are written with round brackets (). The only difference between List and Tuple is that you cannot modify the values of the list once created. \\n That means you cannot add or remove elements to the tuple. \\n This makes your next task easier :) \\n\\n Task 23 \\n Create a tuple with values 100,200,300 and perform the following operations: \\n 1.

In Python dictionaries are written with curly brackets{}, and they have keys and values. \\n Syntax: {key:value, key2:value2}\\n Unlike Tuples, you can modify the values here, like this, dictionary_name['key']= new_value \\n To print only the keys, \\n for i in dictionary_name: \\n\\tprint(i) \\n To print only the values, \\n for i in dict_name: \\n\\tprint(dict_name[i]) \\n To print both key and value, \\n for i,j in dict_name.items(): \\n\\tprint(i,j) \\n Here's your task: \\n\\n Task 24 \\n Initialize a dictionary with the key:values : 1:'one', 2:'two', 3: 'three' Your task is to print the elements of the dictionary(1. Keys only, 2. Values only, 3. Both key and values together) and print the length of the dictionary. Also, add the key:value pair, 4:'four' directly by assigning them to the dictionary, and print the updated dictionary(keys and values)\"\n },\n {\n \"task\": \"\\n We have come to the last section of Python basics. \\n Congrats on reaching the 25th Task! \\n Next topic is Exception Handling \\n When an error occurs, or exception as we call it, Python will normally stop and generate an error message. These exceptions can be handled using the try statement. \\n Eg: try: \\n\\tprint(i) \\n except: \\n\\tprint('An Exception Occured') \\n When the try block raises an error, the except block statement gets executed.
