# Computer Science Learning Resources (To get a Job in Tech) Assuming you get to this place a year or at least 6 months before you start your job search, the resources below will help you get a job regardless of your location/familiarity with computer science. Disclaimer: This doesn't make you a brilliant computer scientist but an excellent bread winner. ## Learn a Language Many people avoid learning Python because the availibility of libraries make it difficult to test your ability manipulate data structures, but regardless I am only including the 3 prominent languages here with short links to other 2 which are getting popular. **Languages for DSA covered here** - Python - C++ - Java You can look up the pros and cons of learning each with a quick google search of "Language 1" Vs "Language 2" ### Python(Resources) + https://www.codecademy.com/catalog/language/python [Recommended] + https://www.youtube.com/playlist?list=PL-osiE80TeTt2d9bfVyTiXJA-UTHn6WwU + https://www.youtube.com/watch?v=rfscVS0vtbw + https://www.youtube.com/watch?v=rfscVS0vtbw&list=PLWKjhJtqVAbnqBxcdjVGgT3uVR10bzTEB + https://www.youtube.com/watch?v=8ext9G7xspg + https://www.youtube.com/watch?v=8DvywoWv6fI + https://www.udacity.com/course/data-structures-and-algorithms-in-python--ud513?irclickid=T4iyYGz1BxyLRoUwUx0Mo3EFUkEwt01MDzuOQA0&irgwc=1&utm_source=affiliate&utm_medium=&aff=259799&utm_term=&utm_campaign=__&utm_content=&adid=788805 + https://www.coursera.org/projects/introduction-to-python + https://runestone.academy/runestone/books/published/pythonds/index.html + https://www.geeksforgeeks.org/python-programming-language/ + https://futurecoder.io/ + https://www.fullstackpython.com/ + https://automatetheboringstuff.com/ + https://youtube.com/playlist?list=PL6gx4Cwl9DGAcbMi1sH6oAMk4JHw91mC_ + https://techdevguide.withgoogle.com/ + https://python-course.eu/advanced-python/ + https://www.youtube.com/watch?v=eXBD2bB9-RA&list=PLQVvvaa0QuDeAams7fkdcwOGBpGdHpXln&index=1 + http://www.pythonchallenge.com/ + https://www.udacity.com/course/data-structures-and-algorithms-in-python--ud513 + https://github.com/donnemartin/interactive-coding-challenges + https://www.youtube.com/watch?v=pkYVOmU3MgA&ab_channel=freeCodeCamp.org | https://jovian.ai/learn/data-structures-and-algorithms-in-python [recommended] ### C++ (Resources) + https://www.learncpp.com/ + https://practice.geeksforgeeks.org/batch/fork-cpp + https://www.edx.org/learn/c-plus-plus + https://www.youtube.com/watch?v=A3VQKXBLstw&list=PLEbnTDJUr_Ie_XH-FZN7zCdU7z_EvUmEg [comprehensive] + https://www.udacity.com/course/c-for-programmers--ud210 + https://www.youtube.com/playlist?list=PLLYz8uHU480j37APNXBdPz7YzAi4XlQUF + https://www.youtube.com/watch?v=z9bZufPHFLU&list=PLfqMhTWNBTe0b2nM6JHVCnAkhQRGiZMSJ&ab_channel=ApnaCollege [Language Barrier, but the syllabus is almost exhaustive so definitely worth it to just refer is as curriculum] ### Java (Resources) - https://www.udacity.com/course/java-programming-basics--ud282 - https://www.udacity.com/course/object-oriented-programming-in-java--ud283 - https://beginnersbook.com/java-tutorial-for-beginners-with-examples/ - https://www.coursera.org/learn/object-oriented-java?ranMID=40328&ranEAID=SAyYsTvLiGQ&ranSiteID=SAyYsTvLiGQ-29tDkJq_MFdgmJDSiq2LNw&siteID=SAyYsTvLiGQ-29tDkJq_MFdgmJDSiq2LNw&utm_content=10&utm_medium=partners&utm_source=linkshare&utm_campaign=SAyYsTvLiGQ - https://www.edx.org/course/learn-to-program-in-java-2?source=aw&awc=6798_1606627150_a3df9ef86729a1413ed1f654d1e3b203&utm_source=aw&utm_medium=affiliate_partner&utm_content=text-link&utm_term=301045_https%3A%2F%2Fwww.class-central.com%2F - https://www.geeksforgeeks.org/java-how-to-start-learning-java/ ## DATA STRUCTURES & ALGORITHMS Now you have understood the syntax of your preferred language and need to hon your problem solving skills.
