Covert input into list elements in python -

i have input in python looks this:

20.1 25.9 31.2 33.2 31.2 25.5 28.1 23.2 stop 

it sequence of floating point numbers, each on separate line. wish iterate on them or convert them list iterate, can't find right way it. far have tried this:

    list = [float(n) n in input().split('\n')] 

but returns me first value. wish convert values list , keep integrity of them.

the input function reads single line. need call multiple times , check 'stop'.

import sys  mylist = [] line in sys.stdin:     if line.startswith('stop'):         break     else:         mylist.append(float(line))  print(mylist) 

itertools.dropwhile can of work you. give function returns false value when iteration should stop, plus sequence, , can work in list comprension.

import sys import itertools  def not_stop_condition(line):     """return true unless line 'stop' seen"""     return not line.startswith('stop')  mylist = [float(line) line in itertools.takewhile(     not_stop_condition, sys.stdin)]  print(mylist) 

small functions implement simple expression not_stop_condition can placed in-line in lambda. lambda anonymous function - called number of parameters , returns whatever expression evaluates to.

import sys import itertools  mylist = [float(line) line in itertools.takewhile(     lambda line: not line.startswith('stop'), sys.stdin)] print(mylist)
