python - Replicate identical tuples to N -


this question has answer here:

i have identical tuples of (0, 1) assigned define limits 3 input values:

bounds = ((0, 1), (0, 1), (0, 1))

is there pythonic way assign same tuples n inputs? example:

bounds = ((0, 1), (0, 1), (0, 1), (0, 1), (0, 1), ...nth(0, 1))

you can multiply sequence n shallow copies of contents:

bounds = ((0, 1),) * n

this fine tuples of ints or other immutable data structures containing immutable types, cause surprising behavior if use mutable data structures lists - sequence of n references same list, because it's shallow copy. in case, comprehension idiomatic way create n independent objects:

mutable_bounds = [[0, 1] _ in range(n)]

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
