• Expression: something that needs to be evaluated.
  • a combination of values, variables, operators, and calls to functions: 1+1
  • the evaluation of an expression produces a value
• Statement: instruction that can be executed
  • assignment: x = 1
  • for, while, if, import statements

Pick a previous program: go through the code line by line, which is expression and which is statement?

Review the use of console: from Level 1 exercise 6

import time
from adafruit_circuitplayground.express import cpx

while True:
    print("Temperature C:", cpx.temperature)
    print("Temperature F:", cpx.temperature * 1.8 + 32)
    print((cpx.temperature, cpx.temperature * 1.8 + 32))
    time.sleep(1)

# Execute simple statements/expression using console
y = 3.14
x = len("hello")
print(x)
print(y)

What is the difference between statement and expression from using console?
