this lets us explain our code.

# We can see the values inside of variables by printing them to the terminal

# Python has a special builtin function called 'print' that does this for us

print(foo)

print(bar)

# We assign the result of the expression on the RHS to the name on the LHS

# In this case, the expression on the right is the sum of the variables 'foo'
|

# and 'bar'

summed = foo + bar

# Printing the sum of foo and bar
|
|
# This should output '42' to the screen

|
# You can also re-assign variables
|

bar = 39
|
|
|
|
# This re-assignment does not affect the value of 'summed'
|
|
print(summed) # Still 42
|

# This is because python variables are immediately evaluated on assignment
