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')?
