Code for a Change is an online interactive platform created during COVID-19 outbreak that aims to encourage people to develop programming skills. This community offers free coding lessons in the programming language Python, a coding challenge for beginners, and the opportunity to contribute to a charitable cause.

Learn.
STEM.
Community.
Practice.

Put your Python coding skills into practice with beginner-friendly challenges based on bioinformatics problems that, on a larger scale, computational scientists have to deal with in their daily research. Bioinformatics is a field that tackles biological questions using computational methods and software tools. It combines biology, computer science, maths and statistics to analyse and interpret large and complex data.

First edition: Hack The Virus

Ready for the challenge? Practice your Python skills in our first edition of #HackTheVirus Challenge. There are a total of three tasks to solve, which are meant to be challenging for coding beginners. Each question has hints and example solutions, which also work on your phone for you to code on the go. 

Just getting started? Try solving our lessons for beginners first.

Inspiring women in STEM

“Science is not a boy’s game, it’s not a girl’s game. It’s everyone’s game. It’s about where we are and where we’re going. Space travel benefits us here on Earth. And we ain’t stopped yet. There’s more exploration to come.”

Nichelle NicholsFormer NASA Ambassador and Star Trek actress

“People ask me all the time: ‘What is it like to be a woman at Google?’ I’m not a woman at Google, I’m a geek at Google. And being a geek is just great. I’m a geek, I like to code, I even like to use spreadsheets when I cook.”

Marissa MayerTechnologist and former CEO of Yahoo

“If you know you are on the right track, if you have this inner knowledge, then nobody can turn you off… no matter what they say.”

Barbara McClintockCytogeneticist and winner of the 1983 Nobel Prize in Physiology or Medicine

“Certain people discouraged me, saying science was not a good career for women. That pushed me even more to persevere.”

Francoise BarreVirologist who won the 2008 Nobel Prize in Physiology and Medicine

“Science, for me, gives a partial explanation for life. In so far as it goes, it is based on fact, experience and experiment.”

Rosalind FranklinChemist, molecular biologist, and one of the key figures behind unlocking the structure of human DNA

“Let us choose for ourselves our path in life, and let us try to strew that path with flowers.”

Emilie du ChateletMathematician, physicist and author

“Don’t let anyone rob you of your imagination, your creativity, or your curiosity. It’s your place in the world; it’s your life. Go on and do all you can with it, and make it the life you want to live.”

Mae JemisonFirst African American woman astronaut in space

“I was taught that the way of progress was neither swift nor easy.”

Marie CurieFirst woman to win a Nobel Prize, the only woman in history to ever win it twice, and the only human to ever win a Nobel Prize in two different sciences

“Life need not be easy, provided only that it is not empty.”

Lise MeitnerPhysicist and one of the key reasons we actually understand what nuclear fission is today

“All sorts of things can happen when you’re open to new ideas and playing around with things.”

Stephanie KwolekChemist who invented Kevlar and winner of the Lavoisier Medal for technical achievements

“As always in life, people want a simple answer . . . and it’s always wrong.”

Susan GreenfieldNeurochemist currently researching Parkinson‘s and Alzheimer’s diseases

“Courage is like — it’s a habitus, a habit, a virtue: you get it by courageous acts. It’s like you learn to swim by swimming. You learn courage by couraging.”

Marie DalyFirst African-American woman to earn a PhD in chemistry

“For a research worker the unforgotten moments of his life are those rare ones which come after years of plodding work, when the veil over natures secret seems suddenly to lift & when what was dark & chaotic appears in a clear & beautiful light & pattern.”

Gerty CoriNobel Prize winner in Physiology or Medicine for her work in metabolizing carbohydrates

“I didn’t want to just know names of things. I remember really wanting to know how it all worked.”

Elizabeth BlackburnWinner of the 2009 Nobel Prize for Physiology or Medicine
