--Coding, it's an endless process of trial and error, of trying to get the right command in the right place, with sometimes just a semicolon making the difference between success and failure. Code breaks and then it falls apart, and it often takes many, many tries until that magical moment when what you're trying to build comes to life -- Reshma Saujani, Founder of Girls Who Code
Girls Who Code activities focus on the Core4, which are the four basic programming concepts. They include: variables, loops, conditionals and functions. When you work on your chosen platform, focus on the Core4 concepts.
Trinket is an online IDE( integrated development environment) where you can practice python coding.
Try the Trinket code that is embedded on this web page. Link to the Trinket itself: run the code and change it to experiment.
Then, sign up for your own free account at trinket.io and challenge yourself to code, using the examples on this page as a model.
Core4
Definition
Example
Try It in Trinket
Variables
store data and give them names,including numbers, strings and Booleans.
Variable Try It
Conditionals
a statement that is true IF something else is true: an If...Then statement
Conditional Try It
Loops
code that repeats for a certain number of times, or while something is true
Loops Try It
Functions
Reusable Code: If you find yourself doing something more than once, make it a function
Functions Try It
Copy and paste the following code into a new Trinket: change it around for different subjects: don't forget to change the number you are dividing by. I
created my own Calculator you can try.
#GPA calculator
math = int(input("What's your grade in math?\n"))
science = int(input("What's your grade in science?\n"))
history = int(input("What's your grade in history?\n"))
english = int(input("What's your grade in english?\n"))
average=(math + science + history + english)/4
print ("Your average is ") + str(average)
