Variable assignment in expressions

Question

Here is my code to generate values in the fibonnacci sequence below 10,000,000.

  3 fibs = [1,1]
  4 while((x = fibs[-1] + fibs[-2]) <= 10000000):
  5             


        

Answer 1

In Python, assignment is not an expression, and therefore has no value.

The simplest solution is to do the assignment in the first part of the loop:

fibs=[1,1]
while fibs[-1] <= 10000000:
   fibs.append(fibs[-1] + fibs[-2])
