Yes i realize this is the fibonacci sequence and i understand the math im just having trouble understanding the line in red what does it equate to in laymans terms?
Thanks in advance :D

Traditional way to do this is by temporary variable, because we need the old value of b in two formulas on the right side. Let's call the temporary variable new_b:

a,b=0,1
while b < 100:
print b
new_b = a + b
a = b
b = new_b

alternatively you can become clever and deside that it does not matter to destroy old value of b as the new value is a+b and the old b is a+b-a:

a,b=0,1
while b < 100:
print b
b = a + b
a = b - a

Best way of course is the original Pythonic double assignment, where right hand values have the old variable values before the assignments.

Hello there guys! I must implement a linked list in assembly (using MIPS). We're supposed to dynamically allocate memory for the nodes. This is what I am asked to do: ...
