Q:

multiply a list by a number until all numbers in list are >=1

I want to multiply y_list by a number until all numbers in list are >=1,
and then just print the new list (without Numpy if it is possible).
Maybe multiply y_list as a row and numbers in i_list=[range(1,20)] as a column. and then stop when all numbers are bigger than 1.
For example: y_list= [1.0, 0.5669650111879195] to  until y_list=[2.0, 1.12.. ]
y_list= [1.0, 0.5669650111879195]
i=0
while all(y <= 1 for y in y_list):
    i+=1
    if all(y<= 1 for y in y_list):
        break
    print(i)

A:

If you do need to multiply it by a number (let's assume it to be 1.3) until all the elements are larger than one, the following is the way to go:
y_list = [1.0, 0.1, 0.2, 0.01]
k = 1.3
while any(y<=1 for y in y_list):
    y_list = [y*k for y in y_list]

>>> print(y_list)
[112.45540695195751, 11.245540695195746, 22.491081390391493, 1.1245540695195746]
