    Introduction to Python

    Run the hidden code cell below to import the data used in this course.

    Take Notes

    Add notes about the concepts you've learned and code cells with code you want to keep.

    • In order to execute a command and create output, the command 'print()' must be used
    • Variables can be created using e.g. varibale = value
    • bool = True or False functions (caps is important)
    • float = whole or fractional integers
    • int = integer/whole numbers
    • str = a type to represent text
    • These behave differently
    • To find out the type of a value or a variable that refers to that value, you can use the type() function.
    # Addition, subtraction
    print(5 + 5)
    print(5 - 5)
    
    # Multiplication, division, modulo, and exponentiation
    print(3 * 5)
    print(10 / 2)
    print(18 % 7)
    print(4 ** 2)
    
    # How much is your $100 worth after 7 years?
    print(100 * (1.1 ** 7))

    Explore Datasets

    Use the arrays imported in the first cell to explore the data and practice your skills!

    • Print out the weight of the first ten baseball players.
    • What is the median weight of all baseball players in the data?
    • Print out the names of all players with a height greater than 80 (heights are in inches).
    • Who is taller on average? Baseball players or soccer players? Keep in mind that baseball heights are stored in inches!
    • The values in soccer_shooting are decimals. Convert them to whole numbers (e.g., 0.98 becomes 98).
    • Do taller players get higher ratings? Calculate the correlation between soccer_ratings and soccer_heights to find out!
    • What is the average rating for attacking players ('A')?
